Doctors for Cataract Surgery in Delhi

Cataract surgery is a medical treatment used to repair cataracts, which are caused by obscuring of the lens that is naturally present in the eye.

There are two primary methods of cataract surgery:

• 1. Phacoemulsification: This is the most common technique used today. A tiny incision in the cornea is made, and a little probe is inserted. The ultrasonic waves emitted by the probe break up the hazy lens into tiny fragments, which are subsequently suctioned out of the eye.
• After the lens is removed, the IOL is implanted in its place.
• 2. Extracapsular cataract extraction (ECCE): This method is used in more advanced cases where phacoemulsification may not be suitable. To remove the clouded lens in one piece, a bigger incision is made in the cornea or the white area of the eye (sclera). The IOL is then inserted.

Both techniques are performed under local anaesthesia, which numbs the eye, and patients may also receive sedation to help them relax during the procedure.

It is important to note that cataract surgery does not prevent or treat other eye conditions, such as age-related macular degeneration or glaucoma, which may require additional treatment.

There are different types of cataract surgery techniques available, depending on the specific needs and characteristics of the patient's eye. Cataract surgery is classified into two types:

• 1. Phacoemulsification: This is the most popular and commonly utilised cataract surgery technique. An ultrasonic device is used to break up the hazy lens into little fragments, which are subsequently suctioned out of the eye. Phacoemulsification necessitates a very small incision in the cornea (typically around 2-3 mm). Following the removal of the cataract, an intraocular lens (IOL) is placed to replace the natural lens. There are various advantages of phacoemulsification, including faster healing time, less discomfort, and a lower chance of complications.
• 2. Extracapsular Cataract Extraction (ECCE): This technique is generally used in cases where phacoemulsification may not be suitable, such as when the cataract is too dense or if the patient has certain eye conditions. ECCE requires a larger incision compared to phacoemulsification and may involve more sutures. This technique is less commonly performed nowadays, but it may still be used in specific cases.
• Aside from these two major procedures, there are several variations and breakthroughs in cataract surgery, including:
• - Femtosecond laser-assisted cataract surgery (FLACS): A laser is used to conduct some of the steps in cataract surgery, such as making precise incisions, splitting up the lens, and lowering the cataract. FLACS can offer increased precision and potentially reduce the reliance on handheld instruments.
• - Laser-assisted arcuate keratotomy: This procedure is often combined with cataract surgery for patients with astigmatism. It uses a laser to make small incisions in the cornea, which can help correct astigmatism and improve vision without the need for additional incisions or stitches.

Before undergoing cataract surgery in Delhi or any other location, the ophthalmologist will typically conduct a comprehensive eye examination to assess your eye health and determine the appropriate treatment plan. The specific tests and evaluations may vary based on individual circumstances, but here are some common diagnostic procedures and tests:

• 1. Visual Acuity Test: This test measures your visual clarity and involves reading letters or symbols from an eye chart to determine the extent of your vision loss.
• 2. Slit Lamp Examination: The ophthalmologist uses a specialised microscope called a slit lamp to examine the structures of the front of your eye, including the cornea, iris, and lens. This helps to evaluate the extent of cataract formation and assess any other abnormalities.
• 3. Dilated Eye Examination: The doctor administers eye drops to dilate your pupils, allowing a more detailed examination of the back of the eye, including the retina and optic nerve. This helps to identify any other eye conditions or complications that may impact the cataract surgery or the choice of intraocular lens.
• 4. Biometry: This test determines the optimal quality of the intraocular lens (IOL) that will be placed after the surgery by measuring the dimensions and form of your eye. It may involve using devices like an optical biometer or A-scan ultrasound.
• 5. Fundus Examination: The doctor examines the inside of your eye, including the retina and blood vessels, using a specialised ophthalmoscope or other imaging techniques. This helps to detect any retinal abnormalities or diseases that may require further treatment or management.
• 6. Keratometry: This test measures the curvature of the cornea, which is essential for calculating the correct power of the IOL. It may involve using a keratometer or corneal topography device.

Based on the results of these examinations and tests, the ophthalmologist will discuss the findings with you, explain the treatment options, and determine the best course of action, including the type of cataract surgery and the selection of the appropriate intraocular lens. They will also provide instructions regarding any necessary preparations before the surgery, such as fasting requirements or discontinuing certain medications.

Cataract surgery is typically performed as an outpatient procedure and involves the following steps:

• 1. Anaesthesia: Before the surgery begins, the eye surgeon administers local anaesthesia to numb the eye. This can be done with eye drops, an injection near the eye, or a combination of both.
• 2. Incision: The incision can be made using a scalpel or through the use of a femtosecond laser in certain cases.
• 3. Capsulotomy: Using delicate instruments or a laser, the surgeon creates an opening in the front portion of the thin capsule that surrounds the natural lens. This opening allows access to the cataract.
• 4. Phacoemulsification or Lens Removal: In phacoemulsification, the surgeon inserts a thin probe into the eye through the incision. In cases where phacoemulsification is not suitable, such as with very dense cataracts, the surgeon may perform an extracapsular cataract extraction (ECCE) to remove the lens in one piece.
• 5. Intraocular Lens (IOL) Implantation: After removing the cataract, an artificial intraocular lens (IOL) is inserted into the empty lens capsule.The intraocular lens (IOL) is either folded or wrapped and implanted through the same tiny incision. It unfolds or unravels once set to substitute the natural lens and restores vision. The IOL is permanent in the eye and doesn't need any particular care.
• 6. Closure: The surgeon ensures that the IOL is properly positioned, and the incision is self-sealing in most cases, requiring no sutures.

The eye may be shielded with a protective cover or patch, and your surgeon will provide instructions on post-operative care, such as using prescribed eye drops, avoiding strenuous activities, and attending follow-up visits.

Some of the potential side effects and complications of cataract surgery include:

• 1. Infection: Symptoms may include increased eye redness, pain, swelling, or discharge.
• 2. Swelling or Fluid Retention: In some cases, the cornea may temporarily retain fluid or swell, leading to blurred vision. This is usually a temporary condition that improves with time and appropriate treatment.
• 3. Increased Intraocular Pressure: Occasionally, the surgery may cause a temporary increase in intraocular pressure, leading to discomfort, blurred vision, or, rarely, damage to the optic nerve. This condition is typically managed with eye drops or other medications.
• 4. Posterior Capsule Opacification (PCO): In some cases, a cloudy layer may develop behind the artificial lens (IOL) months or years after cataract surgery. This can cause blurred vision similar to that of a cataract.
• 5. Dislocation of Intraocular Lens (IOL): The implanted IOL may rarely become dislocated or move out of position, causing visual disturbances.
• 6. Glaucoma: In some cases, cataract surgery may lead to an increase in intraocular pressure, contributing to the development or progression of glaucoma. This can usually be managed with medications or other treatments.
• 7. Visual Disturbances: Some patients may experience temporary or permanent changes in vision after cataract surgery, such as glare, halos around lights, or difficulty with night vision.

Most complications are rare, and the benefits of cataract surgery in restoring vision often outweigh the risks.

The recovery process after cataract surgery is generally smooth and relatively quick. Here's a general overview of the recovery timeline:

• 1. Immediately After Surgery: Your eye may be shielded with a protective covering or patch during this time.
• 2. Discharge on the Same Day: In most cases, cataract surgery is performed as an outpatient procedure, and you can usually return home on the same day.
• 3. Initial Recovery Period (First Few Days): During the first few days following surgery, it's normal to experience mild discomfort, itching, or a gritty sensation in the operated eye.The eye drops prescribed by your surgeon should be used as directed to aid in the healing process and prevent infection.
• 4. Vision Improvement: Your vision may initially be blurry or hazy immediately after surgery, but it should start to improve within a few days. The full benefits of the surgery may take some time to manifest, and your vision may continue to stabilise and sharpen over the following weeks.
• 5. Follow-up Visits: Follow your surgeon's instructions regarding these visits and any medications or eye drops prescribed.
• 6. Return to Normal Activities: It's important to avoid any strenuous activities, heavy lifting, or activities that may put pressure on your eye for several weeks as advised by your surgeon.

The exact duration of the recovery process may vary from person to person, depending on factors such as overall health, the complexity of the surgery, and any pre-existing eye conditions.

If you have any concerns or experience severe pain, sudden vision changes, excessive redness, or any unusual symptoms during your recovery, it's important to contact your surgeon or seek immediate medical attention.
