What is cataract?
Cataract is one of the most common eye conditions, especially with advancing age. It refers to the clouding of the lens in one or both eyes, causing blurred and hazy vision. This condition progresses over time until the lens becomes completely opaque, preventing the passage of light rays through it. There are several medical terms commonly used to refer to this disease, such as “white water” (literal translation) and cataract.
What is the difference between white water and blue water in the eye?
One of the frequently asked questions at Dr. Ammar Nasr’s clinic is: “What is the difference between white water and blue water in the eye, and how can we distinguish between them?”
In reality, one condition arises from the other. When the white water condition progresses and is left untreated, it leads to the development of blue water. In the language of ophthalmology, white water refers to the opacity of the lens and the blurred vision caused by the breakdown of the protein fibers and various components of the lens. Over time, these components condense randomly and result in a more severe condition known as blue water, which coincides with an increase in eye pressure and can lead to optic nerve atrophy and partial or complete blindness.
Types of cataracts in the eye
The types of cataracts that affect the eye vary depending on the location of the condition, its severity, and the associated risk factors. They can be classified into three main types that encompass all detailed cases, as follows:
- Nuclear cataracts: In this condition, opacity or cloudiness occurs specifically in the central part of the lens. The severity of the opacity indicates the degree of hardness or maturity of the cataract. If left untreated, the nuclear cataract tends to turn into a brown cloudy lens. The progression of the disease leads to a very slow deterioration of distance vision. This condition mainly affects individuals over the age of 75, and surgical intervention is often the definitive treatment.
- Cortical cataracts: This type affects the outer layer of the lens, known as the cortex. It occurs due to changes in the lens components, resulting in fissures that extend from the outer part of the lens toward its center. A prominent symptom of this type of cataract is severe discomfort from glare, caused by the refraction of light through the fissures.
-
Posterior subcapsular cataracts: This is a silent condition that is difficult to detect in its early stages. It manifests as a dark spot in the posterior part of the lens, just beneath the lens capsule. This type is characterized by a significant decrease in vision quality in brightly lit environments and an inability to see near objects clearly. It primarily affects children and young adults more than the two types mentioned earlier.
Other Types of Cataracts
In addition to the mentioned types, there are several exceptional types of cataracts that affect both adults and children, some of which occur in specific cases, while others are more widespread. These include:
Congenital cataracts: In this case, infants are born with cataracts due to various genetic or hereditary reasons.
Mature white cataracts (Morgagnian cataracts): In this condition, the cortical region of the lens becomes highly liquefied, with the nucleus of the lens suspended on the lens capsule. This may result in lens disintegration and liquefaction, leading to complicated surgical procedures.
Mature cataracts: This is a distinct type characterized by the absence of infrared (IR) reflection, partial whitening of the lens cortex, and blurry vision.
Immature cataracts: This type is characterized by the visibility of the retina and the preservation of its ability to reflect infrared radiation from the background of the eye, accompanied by a decrease in vision.
What are the symptoms of cataracts in the eye?
Each case of cataracts is unique, and each patient’s condition differs based on the extent of lens opacity, its precise location, the progression of the disease, and other factors. However, the most common and widespread symptoms among cataract patients can be listed as follows:
- Gradual vision impairment without associated pain.
- Discomfort from bright screens such as TV and mobile devices.
- Difficulty in recognizing people’s faces and distinguishing them.
- Inability to read smoothly.
- Double vision in one eye.
- Noticing halos around light sources, especially at night.
- Changes in refractive measurements, such as nearsightedness and farsightedness.
- Sensitivity to light.
- Dim and faded perception of colors.
- Episodes of sudden severe headaches.
- Partial loss of vision.
- Change in the color of the lens to white
Causes of Cataract
While age is the most common factor in developing cataracts in the eye, many cases result from various and simultaneous causes. These causes may be overlooked when they occur, but their consequences can be extremely severe. Some of the causes include:
- Genetic factor: When one or both parents have cataracts, their offspring are more likely to develop them due to genetic or hereditary reasons.
- Aging: As mentioned earlier, age-related cataracts are common and result from the physiological changes in the human body that affect the protein composition of the lens, leading to the formation of cataracts.
- Diabetes: One of the most prominent complications of diabetes is ocular damage, which directly affects the optic nerve.
- Radiation exposure: Certain harmful types of radiation, such as those used in cancer treatment, can contribute to the development of cataracts.
- Certain medications: Each medication has its side effects, and this applies to corticosteroids as well. Prolonged and high-dose use of corticosteroids can affect the eye and lead to cataracts.
- Metabolic disorders: Diseases such as congenital rubella syndrome, herpes, measles, and genetic metabolic disorders can contribute to the development of cataracts.
- Progression of eye diseases: Neglecting the treatment of minor eye conditions such as iritis can result in the accumulation of cataracts.
- Severe trauma: In cases of fights or accidents, a small incision may occur in the lens capsule, allowing the intraocular fluid to enter the lens and leading to the formation of cataracts.
- Intentional injuries: These refer to deliberate corneal incisions or surface or deep wounds, which cause disruption of the lens capsule and the interaction of its components with the eye’s fluids, resulting in cataract formation.
When is cataract surgery necessary?
Many patients tend to neglect early-stage cataracts, believing that they do not significantly affect their vision quality and, therefore, do not require immediate treatment. However, cataracts can progress rapidly and cause a sudden decline in vision. At this point, it becomes necessary for the patient to seek medical attention because cataracts have started to interfere with their daily activities. Neglecting cataract treatment can lead to several problems, including:
- Increased eye pressure, known as glaucoma
- Dislocation of the lens due to the dissolution of the lens zonules, leading to lens drop and more serious complications
How is cataract diagnosed?
In mild cases and in the early stages of cataract development, advanced diagnostic techniques are used to detect the condition. However, in advanced cases where lens opacity is significant, you can diagnose your own condition and those around you because cataracts are visible and apparent. Of course, this does not replace consulting a doctor and initiating immediate treatment to avoid vision loss. The doctor may use various diagnostic mechanisms, including:
- Comprehensive eye examination: This involves confirming the presence of cataracts and evaluating vision using an eye chart.
- Intraocular pressure measurement test: This involves a sudden puff of high-pressure air directed at the cornea to accurately measure eye pressure.
- Clinical examination: Initially, dilating eye drops are used to examine the health and integrity of the optic nerve and exclude any retinal damage.
- Slit lamp examination: This device enlarges ocular tissues under a microscope, allowing for the examination and assessment of ocular tissues and their health.
- Additional tests: The specialist may require additional tests, such as measuring the eye’s response to intense glare and assessing color discrimination ability, among others.
Types of Cataract Surgery
At Dr. Ammar’s center, cataract surgery can be performed using various techniques, including modern and advanced methods, as well as traditional surgery. Each technique has multiple steps and specific details, as follows:
Laser-Assisted Cataract Surgery
This technique is one of the most widespread and globally recognized procedures for cataract treatment due to its high success rates and suitability for most cataract cases. It does not require the use of surgical blades and involves the following steps:
- Automated laser beams create a precise incision, usually around 2 mm, with controlled timing and direction.
- The laser beams penetrate the lens through the incision and fragment the accumulated cataract into tiny pieces.
- The surgeon inserts a probe connected to a device called a “phaco” through the incision, which emulsifies and removes the fragmented particles.
- An artificial lens is implanted behind the iris and secured in place, completing the procedure.
Phacoemulsification Cataract Surgery
Also known as “lens emulsification surgery,” this technique is less advanced than the laser-assisted method but equally important. The steps involved are as follows:
A highly skilled ophthalmologist performs a very small surgical incision.
Ultrasound waves are directed toward the incision to emulsify the cataract-affected lens.
A new, foldable lens is implanted through the surgical incision.
The lens self-expands and positions correctly, completing the procedure.
Traditional Cataract Surgery
This method, also known as extracapsular cataract extraction, is one of the oldest techniques used for cataract treatment and is still effective to this day. The steps involved are as follows:
- The surgeon creates a relatively long and deep surgical incision.
- The cataract-affected lens is manually extracted, either with or without preserving the posterior part of the lens capsule.
- A healthy artificial lens is implanted in place of the extracted lens.
- The surgical incision is closed with sutures and medical grafts, and the eye is dressed for several days.
What are laser vision correction surgeries?
Laser vision correction surgeries, also known as LASIK (Laser-Assisted In Situ Keratomileusis), are specialized medical procedures aimed at correcting refractive errors, specifically vision problems in general. In other words, when there is a refractive error that leads to a disruption in the light’s refraction inside the eye, causing the incoming light rays to not focus correctly on the retina, the most suitable procedure, often involving the use of laser technology, is used to correct this issue. This helps to reposition the light beam correctly onto the retina, resulting in improved visual quality.
Types of refractive errors corrected by laser:
There are four main types of refractive errors that hinder vision and require laser vision correction surgery to address:
- Hyperopia (Farsightedness): In this condition, the light rays converge behind the retina, making it difficult for individuals with hyperopia to see nearby objects clearly.
- Myopia (Nearsightedness): In this case, the focal point of light falls in front of the retina, within the posterior segment of the eye. Individuals with myopia struggle to see distant objects clearly.
- Presbyopia (Age-related farsightedness): This condition occurs with aging when the eye loses its ability to focus on close-up objects and struggles to distinguish between near and far vision. Presbyopia typically sets in at the age of 40 or older.
- Astigmatism: It is one of the most common eye conditions in which the cornea is shaped irregularly, deviating from its natural spherical form. This leads to blurred or distorted vision and visual doubling.
These refractive errors can be corrected through laser vision correction procedures, such as LASIK or other similar techniques.
Types of vision correction surgeries:
Vision correction surgeries vary greatly, ranging from traditional to modern techniques, utilizing advanced medical equipment and sophisticated technologies. However, they all share a common goal, which is to achieve the best possible visual quality. Here, we will briefly discuss some of the notable types of vision correction surgeries:
Laser Vision Correction:
This procedure relies on laser beams to reshape the cornea for better vision. By reshaping the cornea, light can be directed more effectively onto the retina, improving vision significantly. In this procedure, an ophthalmic surgeon creates a flap on the eye, lifts it temporarily, and then laser beams reshape the cornea. The flap is then repositioned, restoring the eye to its original state. Laser vision correction is suitable for cases of myopia, hyperopia, and astigmatism.
Surface Laser Vision Correction (PRK):
In this type of surgery, the superficial layer of the cornea, including the epithelial cells, is removed and reshaped using laser beams. It is also referred to as “Photorefractive Keratectomy” (PRK). Surface laser vision correction is suitable for cases of mild to moderate myopia, hyperopia, and cases with thin corneas.
Epilasik Vision Correction:
This procedure shares many similarities with the previous surgery and follows similar steps, but the key difference lies in the mechanism. While the entire epithelial layer of the cornea is removed in surface laser vision correction, Epilasik preserves the epithelial layer by lifting it first and then repositioning it after the laser correction and reshaping.
FemtoSmile Vision Correction:
In this procedure, a femtosecond laser is used to direct the laser beam towards the middle layers of the cornea. Additionally, a very thin layer of the cornea is separated without affecting the outermost epithelial layer. The surgical incision in FemtoSmile is much smaller compared to traditional LASIK procedures. This type of surgery is commonly performed for myopia correction.
Conductive Keratoplasty (CK):
CK is a medical procedure that utilizes heat to reshape and adjust the curvature of the cornea. It is an effective method that yields remarkable results.
Conductive keratoplasty is most responsive in cases of mild to moderate hyperopia. It can also be beneficial for vision problems in individuals over the age of 40 and those with presbyopia-related issues.
Intraocular Lens Implantation (IOLs):
In this procedure, a healthy lens is brought in and placed in front of the damaged lens of the eye. This procedure is suitable for individuals with severe vision problems.
Alternative lens implantation is suitable for eye conditions that cannot be corrected with regular or surface laser procedures.
Refractive Lens Exchange (RLE):
High-quality artificial lenses are used to replace the original lens of the eye. The difference between this method and the previous one is that in refractive lens exchange, the new lens is implanted while removing the original lens permanently.
This procedure is beneficial for patients with significant refractive errors who do not respond to any type of surface or regular laser procedures.
Conditions for Laser Vision Correction:
If you are experiencing a vision problem and are considering laser vision correction, there are certain conditions that must be met for you to be eligible for the procedure and to ensure its highest success rate. These conditions include:
- Age: You should be over 18 years old, as vision stabilizes and the condition can be assessed within a manageable range.
- No history of eye surgeries, especially heat-based surgeries.
- Stable vision: If you have recently changed your prescription glasses or contact lenses within approximately one year, it is necessary to wait until your vision stabilizes completely.
- No conflicting medications or chronic medical conditions that may interfere with the procedure.
- If you are a married woman, ensure that you are not currently pregnant, and it is preferable to avoid the procedure if you are breastfeeding.
- Hormonal balance and absence of undisclosed underlying health issues or chronic diseases such as diabetes.
- The cornea should not be excessively thin, as this type of cornea is more susceptible to injury during the procedure. The ophthalmologist will determine this based on an assessment.
Steps of Laser Vision Correction:
If you are curious and want to know what happens inside the operating room during a laser vision correction procedure, we will take you on a brief tour that begins with the patient lying on the operating bed and ends with their safe exit from Dr. Ammar Nassar’s center. Follow along with us.
- The patient enters the operating room and sits calmly while a member of the medical staff verifies their personal information and inquires about any recent developments in their condition.
- After ensuring the patient’s health status and compliance with the preoperative instructions, such as discontinuing medications and getting sufficient rest, the patient lies down on the bed. Above them, there is a complete system of laser devices and accessories, along with a computer to monitor the procedure. Before starting the operation, numbing eye drops are applied, and a few minutes are given for the anesthesia to take effect.
- The doctor places a device called an eye speculum on the patient’s eye, which keeps it open and prevents it from closing.
- Now the procedure begins. A suction ring is placed directly above the cornea to create a vacuum and stabilize the eye.
- A functional artificial glass lens is used to immobilize the eye and flatten the cornea as much as possible.
- Dr. Ammar Nassar focuses the laser beams on the surgical area.
- The laser beams create a flap on the corneal surface and enable the suction to be released.
- The newly created flap is lifted, and the precise excimer laser is used in this step to reshape the cornea and correct refractive errors.
- As the procedure nears completion, the patient may detect a peculiar smell similar to burning and may hear a clicking sound. These are normal occurrences.
- Finally, the flap is repositioned back in its original place. If the procedure is Epilasik, a new flap is replaced once the cornea has been reshaped. The cornea gradually heals in its natural position without any visible stitches or sutures.
Contraindications of Laser Vision Correction:
There are exceptional cases or explicit medical conditions that prevent a patient from undergoing laser vision correction surgery. These conditions may result in complications and unwanted side effects. Some of these contraindications include:
- Inflammation or infection of the eyelid.
- Dry eyes and eye irritation.
- Glaucoma (commonly known as “green water”).
- High intraocular pressure. Herpes simplex infection.
- Viral diseases such as herpes zoster.
- Inflammation of the iris.
- Keratoconus.
- Uveitis.
عملية زراعة العدسات لعلاج عيوب الإبصار
تعرف عملية زراعة العدسات لتصحيح مشاكل الإبصار بأنها عملية سهلة و بسيطة يمكن خلالها علاج كل من قصر النظر وطول النظر والاستجماتيزم و غيرها بواسطة عدسات صناعية لاصقة. وهي الخيار البديل الأنسب للمرضى الذين لا تناسبهم تقنية الليزك. وتُزرع العدسة تحديداً وراء القزحية مباشرةً أو بين قرنية العين و القزحية. وتلعب دور رئيسي في تركيز أشعة الضوء على الشبكية بشكل صحيح لتحسين جودة الرؤية قدر الإمكان.
و هناك نوعين لهذه العملية كما سنوضح بالشكل التالي:
1.زراعة عدسة جديدة فوق عدسة العين ICL
في هذه الحالة تكون العدسات المزروعة لينة قابلة للطي بسهولة ويتم خلالها تعزيز الرؤية وتحسين جودة الإبصار بينما يتم الاعتماد على العدسة الأصلية للقراءة. وعند وضعها لا يمكن إزالتها من العين، وهي تناسب مرضى قصر النظر تحديداً، ونذكر منها نوعان:
– عدسة أمامية مثبتة في القزحية
– عدسة خلفية لاصقة
2.إزالة عدسة العين الأصلية و وضع عدسة جديدة
أما في هذه الحالة يتم استبدال عدسة العين البلورية وزرع عدسة جديدة. يمكن القول بأن هذه العملية شبيهة بعملية المياه البيضاء إلى حد ما. ويناسب هذا النوع مرضى طول النظر و الأشخاص الذين شُخصوا بترقق القرنية بحيث لا تنفع لعلاجهم أي من تقنيات الليزك الشائعة. وتُعرف العدسات المستخدمة في هذا النوع بعدسات “Multi vocal” أو “tray vocal” وهي تتيح إمكانية الرؤية للأشياء القريبة و البعيدة بوضوح تام. وتقسم إلى ثلاثة أنواع و هي:
- العدسات أحادية البؤرة.
- والعدسات الانكسارية “TORIC IOL”
- العدسات متعددة البؤر “MULTI FOCAL IOL”.
خطوات عملية زراعة العدسات لعلاج عيوب الإبصار
لا تتعدى المدة الزمنية لإجراء عملية زرع العدسات سوى عدة دقائق فهي من أسرع عمليات العين في الواقع. وتندرج خطوات هذه العملية البسيطة وفق ما يلي:
- يتم تخدير العين بشكل موضعي بواسطة القطرات العينية المخدرة.
- ثم يتم إجراء شق جراحي دقيق جداً و صغير لدرجة أنه لا يُرى بالعين المجردة، و ذلك باستخدام الميكروسكوب الجراحي.
- تُحضر العدسة الجديدة العقيمة و يقوم الطبيب الجراح بطيها بسهولة لأنها مرنة جداً و يُدخلها من الشق الجراحي.
- تستغرق مرحلة إدخال العدسة إلى العين بضع ثوانٍ لا أكثر.
- بشكل تلقائي تنفرد العدسة التي كانت مطوية وتتموضع في مكانها الصحيح بين القزحية والعدسة البلورية. وتعمل على تصحيح عيوب الإبصار بكل سهولة.
أنواع العدسات المستخدمة لتصحيح عيوب الإبصار
تتنوع العدسات المزروعة في العين فلكل مريض ما يناسبه ولكل حالة هناك خيار مفضل من قبل الطبيب. ونذكر من أبرز هذه الأنواع:
- عدسات أمام القزحية: تتم زراعتها في حجرة العين الامامية.
- عدسات خلف القزحية / أمام عدسة العين: تتم زراعتها في حجرة العين الخلفية
الحالات التي تستدعي إجراء عملية زراعة العدسات
كما ذكرنا مسبقاً فإن هذه العملية تناسب المرضى الذين لا تصلح معهم تقنية الليزك المستخدمة في علاج مشاكل الإبصار. ولذلك هناك مرضى مرشحون لزراعة العدسات أكثر من غيرهم و هم:
- مرضى طول النظر الشديد (الذي تجاوز 5 درجات).
- مرضى قصر النظر الشديد ( أكر من -8 درجات).
- الأشخاص الذين يعانون من ضعف في سماكة القرنية بالإضافة إلى مشكلة قصر لنظر. وذلك لأنهم مؤهبون بشكل كبير لحدوث تغيرات متسارعة في سطح القرنية إما تحدب أو تقعر.
- المرضى المصابون بالقرنية المخروطية.
- مرضى المياه البيضاء حيث يتوجب استبدال العدسة كلياً بعدسة جديدة.
ما هي عدسات التراي فوكال التي تتم زراعتها في العين؟
من أشهر أنواع العدسات المزروعة في العين و التي تعالج معظم عيوب الإبصار. تُعرف في قاموس طب العيون بـ العدسات ثلاثية البؤرة وهي عدسات تحاكي العدسة البلورية البشرية إلى حد كبير. ومن خلالها يمكن تصحيح ثلاثة مشاكل إبصار شائعة بشكل كبير تتدرج بدءاً من مشاكل الإبصار القريبة مروراً بالمتوسطة و انتهاءً بالبعيدة.
تناسب العدسات ثلاثية البؤرة المرضى فوق سن الـ 40. على عكس الكثير من العدسات الطبية الأخرى التي تناسب الأشخاص في سن أصغر.
أهم ما تتميز به هذه العدسات إلى جانب أنها تناسب كبار السن هو إمكانية استبدال عدسة العين الطبيعية بها. وبالتالي لا يستشعر المريض بوجود أي شيء. بالإضافة إلى ذلك فبعد وضع هذه العدسة سيتم الاستغناء بشكل نهائي عن عدسات العين الطبية اللاصقة و النظارات الطبية.
مميزات زراعة العدسات لعلاج عيوب الإبصار
لابد أنك تتساءل عن إيجابيات عملية زرع العدسات ومزاياها التي جعلت هذا العدد الهائل من المرضى يلجؤون إليها باطمئنان وأمان. ولذلك إليك أهم مميزات هذه العملية والدوافع التي جعلت أطباء العيون يفضلونها دوناً عن العمليات الأخرى:
المميزات
- إن هذه العدسات دقيقة جداً وغير مرئية وخفيفة الوزن جداً لذلك لن يشعر المريض بوجود أي شيء في عينيه. ولن تسبب له أي إزعاجات.
- تتميز العدسات بشفافية عالية للغاية تسمح بمرور الضوء عبرها و لا يمكن ملاحظتها عند النظر إلى العين مطلقاً.
- تمتلك قدرة تصحيح إبصار عالية جداً، تجعلها قادرة على تصحيح الأخطاء الانكسارية في الحالات الشديدة و المتقدمة. وهنا نتكلم عن قدرة تصحيح تصل إلى حدود +20 إلى -20.
- تم تصميم هذه العدسات لتبقى في العين سنوات مديدة، و بمعنى آخر طيلة فترة حياة الإنسان لذلك لا يمكن أن تتعرض للجفاف أو تتشقق أو تتسخ بل تصبح جزء من العين لا يمكن الاستغناء عنه.
وأيضا
- ثابتة لا تتحرك مهما حصل، وهذا الأمر يقلق الكثير من المرضى الذين يخشون انزياح العدسة أو خروجها من العين.
- لا تحتاج إلى استبدال باستمرار كما في العدسات التقليدية.
- أما فيما يتعلق بعملية زراعة العدسات فهي تتميز بمدتها القصيرة جداً وعدم تسببها بأي آلام او نزوفات عينية.

If you are one of these patients or if one of your relatives is affected by keratoconus and you are searching for the best specialists in this field, you are in the right place. In this article, we will introduce you to the best cornea doctor in Egypt and the Middle East in general. We will also discuss the essential information related to keratoconus, including its causes, symptoms, treatment methods, and answer commonly asked questions about this topic. We wish you an enjoyable read from Dr. Ammar Nassar’s Center.
Get to Know the Best Cornea Doctor in Egypt
How can we determine that an eye doctor is the best among others? What are the qualities that make them stand out? How can we judge a doctor, especially with numerous options and dozens of doctors in one area? All these thoughts can confuse the patient, who fears any harm to their eyes or any small mistake that could lead to vision loss. In fact, every patient has the right to feel this way. However, when we talk about the best eye doctor, we not only focus on surgical procedures or applying the appropriate treatment method but also emphasize the following:
- – Accurate diagnosis.
- – Excellent communication and interaction.
- – Respect for the patient and listening to their concerns.
- – Performing surgical procedures with high skill and expertise.
- – Post-operative follow-up and care.
- – Ensuring the patient’s well-being and achieving the desired results.
All these qualities come together at Dr. Ammar Nassar’s center, which has been ranked among the best eye doctors in the Arab Republic of Egypt. Let’s explore some information about keratoconus before discussing Dr. Ammar Nassar’s academic qualifications and prestigious positions.
What is Keratoconus?
Before discussing keratoconus, let’s understand what the cornea is. The cornea is an extremely thin, highly transparent layer located at the front of the eye, allowing us to see the iris and pupil. The cornea focuses the light rays onto the retina, which is located at the back of the eye. The image is then converted into neural signals and transmitted to the visual center of the brain, where the process of vision occurs. The entire process takes only fractions of a second.
In the case of keratoconus, the spherical appearance of the eye changes, and the cornea’s shape becomes irregular. The cornea’s center thins and bulges outward, causing it to appear conical in shape, hence the name “keratoconus.”
Keratoconus Symptoms
The symptoms of keratoconus vary depending on the severity of the condition and its progression. They include:
- – Blurred and distorted vision.
- – Lack of clarity in vision.
- – Difficulty seeing objects, both near and far.
- – Difficulty with night driving.
- – Photophobia (sensitivity to light) and discomfort from glare.
- – Constant need to change prescription glasses due to changing measurements.
- – Chronic headaches resulting from frequent eye strain.
Complications of Untreated Keratoconus
If the patient neglects their condition and does not seek timely medical intervention, several undesirable complications may occur, including:
- – Rapid corneal swelling, leading to a significant and sudden decrease in vision quality.
- – Collapse of the inner corneal lining.
- – Formation of opacities and permanent cloudy patches that affect vision.
- – Corneal scarring, which is one of the most severe complications that may require urgent corneal transplantation.
Cases Requiring Corneal Transplantation
There are certain medical conditions and exceptional circumstances that necessitate immediate corneal transplantation. Some of these cases include:
- – Presence of corneal scars or ulcers resulting from severe injuries or eye infections.
- – Corneal swelling, as observed in untreated keratoconus cases.
- – Failed previous eye surgeries.
- – Inherited eye diseases, such as Fuchs’ dystrophy.
How to Treat Keratoconus
Dr. Ammar Nasar strives to halt the progression of keratoconus and prevent complications while achieving the best treatment solution to improve visual quality. This is done through the following methods:
Prescription Glasses / Contact Lenses
They are used in cases of mild to moderate keratoconus to significantly improve vision quality.
Implantation of Rings or Inserts
This is the preferred solution for moderate cases, as it corrects the corneal topographic shape and reduces surface irregularities.
Corneal Cross-Linking
One of the best therapeutic interventions when keratoconus is detected early. It involves using ultraviolet light with riboflavin on the cornea to strengthen and increase collagen links, directly stabilizing the cornea and slowing down the progression of the disease.
Surface Laser Corneal Correction
This procedure cannot be generalized to all cases of keratoconus because it is specifically designed for certain situations where the corneal thickness allows the use of low-dose excimer laser. It corrects corneal curvature, treats deformities resulting from corneal damage, and stabilizes the procedure with ultraviolet light. This procedure requires a highly skilled and experienced specialist.
Corneal Transplantation
This is a preferred treatment option for many ophthalmologists, especially when the condition of keratoconus deteriorates, and other treatment methods are ineffective in restoring vision. Partial or full corneal transplantation is considered the most suitable solution.
What is Keratoconus?
Before discussing keratoconus, let’s understand what the cornea is.
The cornea is an extremely thin and highly transparent layer located at the front of the eye, allowing for the visualization of the iris and pupil. The cornea focuses the incoming light rays onto the retina, which is located at the back of the eye. The image is then transmitted as neural signals to the visual center of the brain, where the process of vision occurs. The entire process takes only fractions of a second.
However, in the case of keratoconus, the normal spherical shape of the eye is altered, and the cornea undergoes structural changes. The central area of the cornea becomes thin and bulges outward, causing the cornea to assume a conical shape. This is why it is called keratoconus.
Symptoms of Keratoconus
The symptoms of keratoconus vary depending on the severity of the condition and its progression. They may include:
- Blurred and distorted vision.
- Lack of clarity in near and distant objects.
- Difficulty with night driving.
- Light sensitivity and discomfort from glare.
- The need to constantly change prescription glasses due to changing measurements.
- Chronic headaches resulting from eye strain.
Complications of Untreated Keratoconus
If the condition is neglected, and appropriate medical intervention is not sought in a timely manner, several undesirable complications may occur, including:
- Rapid corneal swelling, leading to a significant and sudden decrease in visual quality.
- Collapse of the inner lining of the cornea.
- Formation of opacities and cloudy patches that permanently affect vision.
- Corneal scarring, which is one of the most severe complications and may require urgent corneal transplantation.
Conditions that Require Corneal Transplantation
There are certain medical conditions and exceptional circumstances that necessitate performing a corneal transplant as soon as possible. Among these cases that require immediate therapeutic intervention, we can mention:
– Presence of scars or ulcers on the cornea resulting from severe injuries or eye infections.
– Corneal swelling, as seen in untreated cases of keratoconus.
– Complex eye surgeries.
– Inherited eye diseases, such as Fuchs’ dystrophy.
Treatment Options for Keratoconus
Dr. Ammar Nassar aims to halt the progression of keratoconus in patients, to prevent complications and achieve the best therapeutic solution for improving visual quality. This is accomplished through:
- Prescription glasses/medical contact lenses: These are used in cases of mild to moderate keratoconus to significantly improve visual acuity.
- Implantation of corneal rings or inserts: This is the preferred solution for moderate cases, as it corrects the corneal shape and reduces surface irregularities.
- Corneal cross-linking: One of the most effective therapeutic interventions when keratoconus is detected early. It involves using ultraviolet light and riboflavin on the cornea to strengthen and increase the number of collagen fibers. This directly stabilizes the cornea and slows down disease progression.
- Surface laser ablation for corneal correction: This procedure cannot be generalized to all cases of keratoconus. It is specifically designed for certain cases where the corneal thickness allows for the use of low-dose excimer laser to correct corneal irregularities resulting from corneal damage. The procedure is further stabilized with ultraviolet light. It is crucial that the performing physician is highly skilled and experienced.
- Corneal transplantation: This is a preferred treatment option for many ophthalmologists, especially when the condition of keratoconus deteriorates to a point where other treatment methods no longer provide sufficient vision correction. Partial or full corneal transplantation remains the most suitable approach.
Types of Corneal Transplantation Procedures
Each patient with keratoconus has a unique condition, and therefore, the treatment approach cannot be standardized for all patients. Among the procedures commonly used to treat this condition are:
- Penetrating Keratoplasty (PKP) – Full Thickness Corneal Transplantation
This procedure is performed when a patient requires the replacement of all layers of the cornea due to extensive damage or severe scarring and ulcers caused by external injuries. In this procedure, the entire lens is replaced, and the new lens is sutured with precise surgical stitches. The healing process typically takes several months.
- Deep Anterior Lamellar Keratoplasty (DALK) – Partial Thickness Corneal Transplantation
Unlike full thickness corneal transplantation, in DALK, only the deeper layers of the cornea are replaced. This procedure is suitable for patients with conditions such as Fuchs’ dystrophy. There are two main types of DALK:
- Descemet’s Membrane Endothelial Keratoplasty (DMEK): In this procedure, both the Descemet’s membrane and the corneal endothelium are transplanted without relying on the stroma. Patients undergoing this type of surgery have fragile and thin corneal tissue, making it necessary for an experienced surgeon to perform the operation. The recovery is typically rapid, and the postoperative improvement is very good.
- Deep Anterior Lamellar Keratoplasty (DALK): This procedure involves the excision of the inner lining of the cornea, along with the underlying Descemet’s membrane. The excised tissue is replaced with a new lamellar graft and Descemet’s membrane. The use of the stromal bed in the middle layer of the cornea facilitates the handling of the new tissues.
- Anterior Lamellar Keratoplasty (ALK) – Superficial Corneal Transplantation
This procedure targets the outer and middle layers of the cornea. These layers are removed and replaced with new layers taken from a recently deceased donor, ensuring their safety. The layers are separated using controlled air currents to facilitate their manipulation. One disadvantage of this procedure is that it is susceptible to rejection, and the patient may require a subsequent full corneal transplantation.
- Corneal Transplantation with Stem Cells
Many scientific studies and research have been conducted, particularly at high-level research centers in the United States, exploring the potential use of stem cells to create a healthy cornea for transplantation instead of a damaged cornea. However, the feasibility of using stem cells for corneal regeneration has not been established to date.
Preoperative Preparations for Corneal Transplantation
Patients should adhere to certain guidelines and instructions provided by their supervising physician to achieve the best possible results from corneal transplantation. Some of these recommendations include:
- Schedule the operation with Dr. Ammar and visit him before the procedure for a comprehensive and rapid eye examination.
- Undergo certain laboratory tests to ensure the patient’s health during and after the procedure, such as bleeding time and clotting speed tests.
- Discontinue certain types of chronic medications as advised by the doctor, such as anticoagulants and antiplatelet drugs like aspirin and clopidogrel.
- The doctor may prescribe certain eye drops, such as antibiotic-containing drops, to prevent bacterial infection during the procedure. In this case, the patient should strictly adhere to the prescribed schedule for applying these drops.
Important Postoperative Tips after Corneal Transplantation
The postoperative period following corneal transplantation is a delicate phase that requires extra attention from the patient and supervision from the medical center to prevent complications and side effects. Some important tips that patients should adhere to include:
- Regularly apply the prescribed eye drops as instructed by the doctor, as they significantly reduce the risk of immune rejection and protect against bacterial infection.
- Wear protective eye shields in the first few days after the procedure to safeguard the eyes from external factors.
- Avoid engaging in vigorous physical exercise and refrain from making sudden movements to keep the transplanted cornea in its proper position.
- Refrain from applying pressure to or rubbing the eyes.
Complications Following the Procedure
While corneal transplantation is one of the most successful and safest eye surgeries, it is worth noting that some patients may engage in improper habits or experience unforeseen accidents that can lead to unwanted complications. Some of these complications include:
- Bacterial infection due to inadequate care and attention to eye dressings.
- Eye hemorrhage, which can occur in some cases as a result of external mechanical trauma.
- Increased intraocular pressure (glaucoma).
- Cloudy opacity above the lens of the eye known as cataract.
- Swelling of the cornea.
- Retinal detachment, where the inner or posterior surface deviates from its normal position.
- Immune rejection of the transplanted cornea, which is the most severe complication.
Find the Best Corneal Doctor in Egypt
Determining the best eye doctor and the qualities that make them stand out can be challenging, especially with numerous options and dozens of doctors in one area. All these thoughts can cloud the patient’s mind, as they fear any harm or minor error that could result in vision loss.
In reality, every patient has the right to be concerned. However, when discussing the best eye doctor, it is not solely about surgical expertise or the correct application of therapeutic procedures. The focus extends to:
- Accurate diagnosis.
- Effective communication and interpersonal skills.
- Respecting the patient and addressing their concerns.
- Performing surgery with precision and high professionalism.
- Postoperative follow-up and patient care.
- Ensuring the patient’s well-being and achieving desired outcomes.
All these qualities are embodied in Dr. Ammar Nassar’s center, which has been recognized as one of the best eye doctors in the Arab Republic of Egypt. Let’s delve into some information about keratoconus before discussing Dr. Ammar Nassar’s academic qualifications and esteemed positions.
Eye cosmetic surgery is the procedure of removing excess sagging skin around the eyes that appears with age or due to genetic or unhealthy behaviors. Eyelid cosmetic surgery is not only performed for cosmetic purposes but can also improve vision in some cases. In this article, Dr. Ammar Nasr explains the details of eyelid cosmetic surgery using laser, the candidates for this procedure, and the expected outcomes.
Eyelid Cosmetic Surgery
Eyelid cosmetic surgery, also known as eyelid lift or blepharoplasty, is a type of cosmetic surgery that addresses droopy eyelids. It may involve removing excess skin, muscles, and fat. As a person ages, the eyelids stretch, and the supporting muscles weaken, leading to the accumulation of excess fat around the eyelids, causing drooping eyebrows and the presence of fatty bags under the eyes. In addition to the appearance of looking older, severe skin sagging can also affect peripheral vision, making upper eyelid surgery a recommended procedure to eliminate these sagging conditions.
Eye Cosmetic Surgery
Drooping eyelids affect the aesthetic appearance of the face, making a young person look much older. Droopy eyelids not only impact the aesthetic appearance but can also lead to difficulties in vision due to their effect on the visual field. For these reasons, cosmetic eyelid surgery has emerged as a simple procedure performed under local anesthesia. Its aim is to modify the shape of the eyelid, remove excess or redistribute fat to restore the natural beauty of the eyelids, enhance the beauty of the eyes, and restore proper vision. However, how is eyelid cosmetic surgery performed? Does it have any risks or side effects? Will there be any traces of the surgery after the procedure? Follow the following paragraphs to find the answers.
How is Eyelid Cosmetic Surgery Performed Using Laser?
Eyelid cosmetic surgery is a simple procedure with significant and impressive results. Dr. Ammar Nassar explains that the surgery is performed by following these steps:
- Diagnosing the patient and subjecting them to a physical examination to discover the extent to which drooping eyelids affect the visual field and to identify the real reason behind the sagging, whether it is due to natural aging or other factors.
- Making a precise incision in the eyelid to get rid of the existing sagging.
- Removing excess fat cells or redistributing them to give the eyelid a natural appearance.
- Adjusting the position of the muscular tissues to tighten the eyelid and make the eye look younger.
- Placing the tear glands in their natural position, as they may be the cause of drooping eyelids in some cases.
- Removing excess skin from the eyelids that was obstructing part of the visual field.
- Cosmetic stitching of the surgical incision to leave no trace after the eyelid cosmetic surgery.
Cases Requiring Eyelid Lift Surgery
Eyelid lift surgery is one of the significant cosmetic surgeries, but it requires certain conditions to be properly performed. Some cases that require eyelid lift surgery include individuals who want to get rid of signs of aging and want to highlight the natural beauty of their eyes. It is also suitable for young people who feel extremely embarrassed due to the appearance of their eyelids not matching their age. Other cases include those suffering from swelling in the upper eyelids, with the possibility of forming what is known as “pockets.” Additionally, individuals with excess skin in the lower eyelids or the presence of fatty bags under the eyes.
Outcomes of Eyelid Lift Surgery
Through eyelid cosmetic surgery, the patient gets rid of one of the most significant signs of aging, highlights the natural beauty of the eyes, and achieves clear vision after the visual field was affected by drooping eyelids. This procedure provides immediate results, as the patient notices that the shape of their eye and eyelids becomes natural and harmonious with their facial features after the recovery period, which usually takes no more than two weeks. Thus, the patient achieves both cosmetic and functional outcomes in a single procedure.
Advantages of Eyelid Cosmetic Surgery
One of the main advantages of eyelid cosmetic surgery is that it does not require general anesthesia; it is fully performed under local anesthesia, avoiding many known risks associated with general anesthesia. In addition to this feature, the procedure has other advantages, such as:
1. There is no visible surgical mark on the eye after the operation. The doctor may use laser to create the surgical incision on the eyelid and then close it with cosmetic sutures in a way that hides the stitches in the eyelid folds, making them not noticeable.
2. The patient can return home on the same day and resume their normal life.
3. The recovery period takes about two weeks.
4. It increases the person’s self-confidence, as previously drooping eyelids were a source of embarrassment and annoyance.
Conditions that Eyelid Lift and Cosmetic Surgery Can Treat
Eyelid lift and cosmetic surgery can address the following conditions:
1. Loose and sagging skin around the eyelids, affecting the visual field.
2. Bulging fat deposits in the eyelids.
3. Bags under the eyes.
4. Drooping lower eyelids that reveal the white area below the iris.
5. Excess skin and fine wrinkles on the lower eyelids.
Before Eyelid Cosmetic Surgery, the Patient Will Undergo the Following:
1. The doctor will inquire about the patient’s medical history, asking about any health conditions, medications, or issues like thyroid problems, high blood pressure, diabetes, or eye problems.
2. A comprehensive medical examination will be conducted, including vision testing and tear production evaluation.
3. Imaging of the eyelids from various positions and angles will be performed to determine the ideal surgical approach and evaluate the potential outcomes.
4. Discontinuing medications that could cause bleeding.
5. Avoiding smoking and alcohol consumption.
Steps of the Procedure
If the patient is undergoing the procedure for both upper and lower eyelids, the doctor will start with the upper eyelids. They will make an incision along the eyelid fold, remove excess skin, muscles, and fat, and then close it. For the lower eyelids, the doctor will make an incision just below the eyelashes, remove excess fat and sagging skin, and then close it after the operation.
Aftercare Instructions for Eyelid Lift and Cosmetic Surgery Include:
1. Using compresses on the eyes.
2. Gently cleaning the eyelids and using prescribed eye drops.
3. Avoiding eye strain or any physical exertion for a week.
4. Completely avoiding smoking.
5. Avoiding rubbing the eyes.
Are There Any Risks to Eyelid Cosmetic Surgery?
Eyelid cosmetic surgery does not involve serious complications when performed by a specialized eye doctor. However, the patient may experience some minor side effects such as temporary eye dryness, slow adjustment to natural eyelid opening and closing, and slight bruising around the eyelids for several days after the operation.
In conclusion, you can consult Dr. Ammar Nasr, an ophthalmologist and eye surgeon, through the contact details provided on the website or visit the nearest available clinic.
The retina of the eye is one of the most important contributors to the process of vision. It works by transmitting light signals to the human brain, which are then transformed into clear images. Retinal detachment is one of the most common diseases affecting the retina and negatively impacting vision. If left untreated, it can eventually lead to vision loss.
However, the treatment methods for retinal detachment vary depending on the stage of the condition. Typically, early-stage treatment involves the use of laser therapy, while late-stage treatment involves vitreous body excision. Therefore, it is crucial to accurately diagnose the patient’s condition before performing retinal detachment surgery.
What is retinal detachment surgery?
The goal of retinal detachment surgery is to repair the damage caused by the vitreous body, which often shrinks and pulls away from the retina, separating it from the eye wall. This can result in either partial or complete retinal detachment.
However, the treatment methods for retinal detachment vary depending on the stage of the condition. Typically, early-stage treatment involves the use of laser therapy, while late-stage treatment involves vitreous body excision.
Therefore, it is crucial to accurately diagnose the patient’s condition before performing retinal detachment surgery.
Diagnosis
There are several methods that aid in diagnosing retinal detachment, including:
-
Fundus examination, which is conducted by applying dilating eye drops to allow the doctor to clearly visualize the patient’s retina and identify any holes, tears, or detachments.
-
Ultrasonography, which involves applying a gel or certain liquid to the eyelid while the patient closes both eyes. An ultrasound device, called ultrasonography, is then directed at the eye to examine and detect symptoms related to retinal detachment.
Treatment of Retinal Detachment
The treatment approach in the early stage differs significantly from the later stages. By early stage, we mean the condition where tears and holes begin to appear on the surface of the retina, followed by a partial detachment resulting from the initial leakage of fluids behind the retina.
Retinal detachment surgery can be performed in these two stages using laser therapy. However, in the later stage of retinal detachment, treatment often involves vitreous body excision.
Laser Treatment for Retinal Detachment
Laser therapy is not considered a definitive solution for this problem except in very early cases. It works by sealing small tears and ruptures in the retina. This technique can also be used to secure the retina to the eye wall by creating scars that connect the retinal tissues to the wall.
Vitreous Body Excision Surgery
Vitreous body excision from the eye is the most well-known and effective procedure for treating retinal detachment. This method involves injecting a certain liquid substance such as silicone oil or a specific type of gas into the eye after removing the vitreous body.
The injected substance, whether it is gas or liquid, pushes the retinal tissues towards the eye wall. Over time, the retina reattaches to its natural position, resulting in a significant improvement in vision for the patient.
When Does Vision Improve After Retinal Detachment Surgery?
The duration of vision improvement varies depending on the type of procedure performed during retinal detachment surgery. In cases treated with laser therapy, patients typically start to experience improved vision after several weeks.
For patients who undergo vitreous body excision and gas injection, improvement is usually noticed after approximately 6 weeks following the procedure.
In cases where the vitreous body is removed and silicone oil is injected, patients typically experience improvement within the first three months after the operation.
However, during this period, the vision may not be sufficiently clear or sharp.
Patients may need to undergo another surgical procedure to remove the injected substance after approximately three months from the initial operation.
Dr. Ammar Nassar, a specialist in retinal surgery, advises undergoing retinal detachment surgery as soon as symptoms of the condition appear or when diagnosed during regular eye examinations.
Intravitreal Injections for the Treatment of Retinal Detachment
When discussing retinal detachment or retinal tears, we are referring to one of the most dangerous retinal diseases. It is among the most severe eye conditions and becomes even more critical in individuals with diabetes.
Intravitreal injections are used to treat retinal detachment at certain stages of the disease. This is explained in more detail by Dr. Ammar Nassar.
What is Retinal Detachment?
Before delving into the process of intravitreal injections for the treatment of retinal detachment, it is necessary to understand what retinal detachment or retinal tears are and the nature of this condition.
Retinal detachment occurs when fluid accumulates in a specific location. It is similar to noticing a wall with leaks or seepage, where you can observe its effects on the wall, such as bulging or peeling paint due to fluid accumulation.
Similarly, retinal detachment involves a disease that affects the retina and causes it to detach or leads to the detachment of the macula, resulting from the accumulation of fluids behind or between its layers. This typically occurs due to weakened blood vessels that nourish the retina, allowing the leakage or proliferation of fluid in abnormal areas (known as proliferative retinopathy).
Therefore, retinal detachment, in simple terms, refers to an increase in the thickness or swelling of certain retinal tissues, which weakens these tissues. In this condition, the sensory receptors of the retina, responsible for receiving and transmitting visual signals to the retinal nerve cells, the optic nerve, and the visual cortex in the brain, are affected. This directly impacts the patient’s vision. In some cases, the doctor may resort to intravitreal injections to treat retinal detachment before the condition progresses and leads to retinal fibrosis or detachment, which complicates the treatment methods.
What are the common eye conditions treated with intraocular injections?
- Age-related macular degeneration
- Diabetic retinopathy
- Macular edema (swelling of the macula)
- Uveitis (inflammation of the uvea)
- Central retinal vein occlusion
What are the symptoms of retinal detachment?
What makes retinal detachment a serious disease is that it may not present any symptoms in the early stages. Patients may remain unaware and neglect to control their blood sugar levels or undergo regular eye examinations. Many people are unaware that blood vessels in diabetic patients are weak, making the retina vulnerable to this disease. It is crucial for patients with diabetes, especially those who have had the disease for more than five years, to undergo regular eye check-ups to ensure that their retinas are not affected. Dr. Ammar Nassar strongly emphasizes this.
In advanced cases or when treatment is neglected (whether it’s retinal injections or other treatments used for different degrees of detachment), symptoms may include:
- Difficulty and blurriness of vision, where patients struggle to see details of objects and faces clearly.
- Appearance of dark spots or floaters in the visual field.
- Unstable vision.
- These symptoms can progress to partial loss of visual field.
How are intraocular injections for retinal treatment performed, and what are their advantages?
Intraocular injections for retinal treatment ensure that the medication reaches the retina with a higher concentration within the eye. They provide direct treatment for retinal diseases, especially those affecting the retina. They improve or slow down the deterioration of vision more effectively. Additionally, when antibiotics are injected near the source of infection, they are more efficient.
How are intraocular injections for retinal treatment performed?
Many individuals seek information about the procedure for intraocular injections for retinal treatment. It is a simple procedure performed in an eye clinic that takes approximately 15 to 30 minutes. The steps include:
- Administering eye drops to dilate the pupil.
- Disinfecting the eye and eyelids to minimize bacteria.
- Numbing the eye using anesthetic eye drops to ensure a painless experience.
- Placing an eyelid speculum to stabilize the eye during the procedure.
- Injecting the medication using a specialized needle into the eye through the conjunctiva (the white part of the eye).
- Patients may feel some pressure during and after the injection, but without any pain.
Does the patient need to undergo repeat injections for retinal treatment?
Some individuals wonder about the need for repeat injections in the eye and whether it is necessary or not.
Dr. Ammar Nassar explains that in most cases, patients may require repeat injections. According to certain protocols, patients may need to undergo injections once a month for a period of three months.
The frequency of injections beyond this duration depends on the improvement achieved in the condition, which is determined and monitored through optical coherence tomography (OCT) imaging.
If the condition improves, the swelling disappears, and the blood vessels stop leaking fluid after three injections, for example, there is no need for further injections unless the swelling recurs.
However, it is crucial for the patient to maintain regular follow-up with the doctor to determine the progress of the condition.
Intraocular injections are considered a safe treatment, and there is no problem if they are administered for several years. Some cases may require repeat injections to slow down disease progression, improve vision, or prevent vision loss in chronic conditions such as central retinal vein occlusion.
Certain cases may require weekly injections, several months of treatment, or longer intervals based on the eye’s condition and its level of improvement. Therefore, it is always advisable for patients to adhere to the prescribed treatment to prevent the deterioration of the eye’s condition. This is how intraocular injections are performed for retinal treatment.
The retina is one of the most important components involved in the process of vision. It is responsible for transmitting light signals to the brain, where they are converted into clear images. Retinal detachment is one of the most common conditions that affect the retina and negatively impact vision. If left untreated, it can eventually lead to vision loss.
The treatment of retinal detachment varies depending on the stage of the condition. In the early stages, laser treatment is usually employed, while in later stages, vitrectomy may be necessary. Therefore, it is crucial to accurately diagnose the patient’s condition before undergoing retinal detachment surgery.
Retinal detachment surgery
What are the techniques used in this procedure? Is vitrectomy the ideal solution for treating retinal detachment? And when can vision improve after this surgery?
Retinal detachment surgery aims to repair the damage caused by the contraction of the vitreous humor, which often leads to pulling and detaching the retina from the eye wall, either partially or completely.
However, the treatment of retinal detachment varies depending on the patient’s specific condition. Laser treatment is typically employed in the early stages, while vitrectomy is performed in the later stages.
Therefore, it is essential to accurately diagnose the patient’s condition before undergoing retinal detachment surgery.
Diagnosis
There are several methods that help diagnose retinal detachment, including:
– Fundus examination, which is performed by placing a dilating drop in the eye to allow the doctor to clearly see the patient’s retina and determine if there are any holes, tears, or detachments in the retina.
– Ultrasound examination, which involves applying a gel or specific fluid to the eyelid while the patient closes both eyes. An ultrasound device is then directed towards the eye to examine it and detect symptoms related to retinal detachment.
Treatment for Retinal Detachment
The treatment approach in the early stage significantly differs from the later stages. By the early stage, we mean the phase where tears and holes start to appear on the surface of the retina, followed by a partial detachment due to fluid leakage behind the retina.
Retinal detachment surgery can be performed in these two stages using laser treatment. In the late stage of retinal detachment, the treatment usually involves vitrectomy, which is the removal of the vitreous humor.
Laser Treatment for Retinal Detachment
Laser treatment is not a definitive solution for this condition except in very early cases. It is only effective in sealing small tears and holes in the retina. This technique can also be used to stabilize the retina by creating scars that connect the retina to the eye wall.

Vitreous Excision Surgery
Vitreous excision from the eye is the most common and effective procedure for treating retinal detachment. This method involves injecting a fluid substance, such as silicone oil or a specific type of gas, into the eye after removing the vitreous body.
The injected substance, whether gas or liquid, pushes the retinal tissues towards the eye wall. Over time, the retina reattaches in its natural position, and the patient experiences significant improvement in vision.
When does vision improve after retinal detachment surgery?
The duration of vision improvement varies depending on the type of procedure performed in this surgery.
In cases of laser treatment, patients start to experience vision improvement after several weeks.
For vitreous excision with gas injection, patients usually notice improvement after about six weeks.
In cases of vitreous excision with silicone oil injection, patients experience improvement during the first three months after the procedure.
However, during this period, vision may not be clear or sharp enough.
After approximately three months from the surgery, the patient needs to undergo another surgical procedure to remove the injected substance.
Dr. Ammar Nassar, a retina specialist, recommends undergoing retinal detachment surgery as soon as symptoms of the condition appear or when it is confirmed during routine eye examinations.
