Best Cataract Surgery in Varanasi
What is a Cataract?
Anything you see is an image that enters your eye in the form of light. Inside your eye is a lens, much like the lens of a camera. The lens focuses the light rays coming through the pupil onto the retina at the back of the eye. The different parts of the retina collect this light and send a message to your brain, enabling you to see. A cloudy lens is called a cataract. It is not a growth or a film over the eye.
Risk Factors For Developing Cataracts Include:
1. Aging - 60 years and above
2. Prolonged use of steroids
3. Excessive exposure to UV rays
5. Eye injury/trauma
6. Alcohol abuse/ chain smoking
A cataract may develop slowly over years or rapidly within months. Often the other eye will also be affected. There are no medications, eye drops or dietary restrictions that can cure or prevent cataract formation. If the cataract interferes with your regular activities the only solution is surgery.
In cataract surgery, an artificial intraocular lens (IOL) replaces your natural clouded lens. Your new lens should restore vision to nearly what it was earlier, though you may need to wear glasses for reading or driving.
Several techniques used for removing cataract are:
Micro Incision Cataract Surgery (MICS):
This is a technique where the cataract is removed manually through an incision small of about 1.8 mm to 2.2 mm.
• No stiches, No pain, No injection
• No white layer
• Recovery time 4-7 days
• Better Contrast & focus
Small Incision Cataract Surgery (SICS):
This is a technique where the cataract is removed manually through an incision small of about 4-6 mm. The small incision heals slow enabling you to recover longer.
In this method a tiny instrument is inserted through a very small incision. The instrument uses ultrasound vibrations to break the cataract into fine pieces; these are then gently suctioned out. The new lens is then inserted into the eye. Usually no stitches are required to close the incision. This minimal surgery allows faster and safer healing, hastening your return to normal activity.
Your doctor will select the method of surgery that is most suitable for your case.
Planning for Surgery
It is not necessary for the cataract to mature fully or for the vision to become totally cloudy before scheduling surgery. You and your ophthalmologist should jointly decide on the time for surgery. Be sure to inform your doctor about any medications or herbal remedies that you may be using.
At the hospital our counselors will help you understand the pre-operative procedures and obtain an estimate of the expenditure involved. Prior to your surgery, you will need to undergo some routine medical and blood tests. An A-scan will help the doctor determine the power of the new lens to be implanted in your eye.
It is good to wash your face thoroughly with soap and water before coming for surgery. You will be advised to use some eye drops. Please follow the instructions carefully as these drops help dilate your eye. If your eye is not properly dilated surgery may be delayed. You may also be advised not to eat or drink anything for a few hours prior to surgery. You can bring only one attendant; children below 15 years are not allowed unless they are patients.
Though the success rate for cataract surgery is almost 98%, sometimes there may be complications. Most of these complications are minor and can be rectified. Your doctor will advise you about any specific issues related to your case.
In the operating room, the area around your eye will be cleaned thoroughly. Sterile drapes will be placed around your head and face with only the eye exposed. Usually a local anesthetic in the form of topical drops is administered next to the eye. Sometimes doctors may have to perform the surgery under general anesthesia. An oxygen tube will be placed near you nose so that you do not feel suffocated.
The actual surgery lasts about 30 minutes. You will be relaxed and awake but feel no pain. The nerves in your eye will be completely numbed so you will not be able to see or move your eye.
Care after Surgery
After surgery a bandage or shield will be placed over your eye. You will be advised to rest till you are ready to leave. You should wear protective glasses or an eye shield in the day and an eye patch at night to avoid accidental injury. The doctor will advise you when you can discontinue using them. You can bathe carefully from below your neck but do not wet the operated eye for 10 days. You may gently clean the eyelids with a piece of cotton boiled in water or a sterilized tissue.
Some Important Tips:
• Do not rub the operated eye.
• Do not use any eye cosmetics until the doctor allows it.
• Do not wash your hair until the doctor says you can
• Shave carefully as soap or water should not enter the eye.
• Avoid any vigorous activity.
• Do not lift heavy things.
• Do not bend or bring your head lower than your waist.
• Avoid driving till your vision improves.
• Avoid sleeping on the operated side.
• No sexual intercourse until permitted by the doctor.
• Avoid alcoholic beverages.
• Watch television for short periods only.

You’ve had a microscopic incision on the surface of your eye. When you blink, you may feel a slightly scratchy sensation until the incision heals. Scratchiness is also a symptom of dry eyes. After surgery, our patients find that using artificial tears helps to alleviate the symptoms.
Wearing your old glasses will not harm your eyes, but since the prescription won’t be optimal for your surgery eye, you will probably see best without them. Most patients feel comfortable by only wearing glasses while reading.
Most cataract surgery patients enjoy a significant improvement in their vision after 5-7 days. You may drive when you feel comfortable.
Your implant is a single-focus lens. If your lens was chosen for distance vision, you will need reading glasses. Some patients elect to have one eye focused for close vision so they can read without glasses. However, this may compromise distant vision. We now can offer you the recently introduced multifocal lenses also by which you can have both distant and near vision. Doctor will recommend best lens suitable as per your eye.

Patients with cataracts see their world through a yellow tint. It’s just like wearing yellow-tinted (“blue-blocker”) sunglasses. These glasses block colors from the lower end of the color spectrum like blues and violets. When the cataract is removed and replaced with a clear implant, you will see these unfamiliar colors again. This may be much more dramatic for some patients than others, depending on the cataract.
