3. Limit Alcohol
4. Keep Blood Sugar in check : Eye complications develop from high blood sugar so be alert
5. Get regular eye check-ups : They can alert you to any problems and are essential
6. Eat a diverse diet with fresh food : Some research shows that eating foods high in antioxidants like fresh fruit and vegetables, vitamins C and E may help prevent cataracts.

Cataract Surgery


A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people. Cataract surgery is the removal of the natural lens of the eye that has developed an opacification and its replacement with an intraocular lens. We at SWECentre have the best eye doctor and specialists in Faridabad for LASIK, Laser and Glaucoma treatments.

How a cataract affects your vision

Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems, such as age-related macular degeneration or diabetic retinopathy.

When considering cataract surgery, keep these questions in mind:

Are you comfortable in your daily activities and driving in day or night, Do you have problems reading or watching television. Do vision problems affect your level of independence. Do bright lights make it more difficult to see.


Complications after cataract surgery are uncommon, and most can be treated successfully.

Cataract surgery risks include:

InflammationInfectionBleedingSwellingDrooping eyelidDislocation of artificial lensRetinal detachmentGlaucomaSecondary cataractLoss of vision.Your risk of complications is greater if you have another eye disease or a serious medical condition. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.Normally you can go home on the same day as your surgery, but you won’t be able to drive, so arrange for a ride home.

What you can expect Before the procedure

A week or so before your surgery, your doctor performs a painless ultrasound test to measure the size and shape of your eye. This helps determine the right type of lens implant (intraocular lens, or IOL). Nearly everyone who has cataract surgery will be given IOLs. These lenses improve your vision by focusing light on the back of your eye. You won’t be able to see or feel the lens. It requires no care and becomes a permanent part of your eye. A variety of IOLs with different features are available. Before surgery, you and your eye doctor will discuss which type of IOL might work best for you and your lifestyle. Cost may also be a factor, as insurance companies may not pay for all types of lenses.
IOLs are made of plastic, acrylic or silicone. Some IOLs block ultraviolet light. Some IOLs are rigid plastic and implanted through an incision that requires several stitches (sutures) to close. However, many IOLs are flexible, allowing a smaller incision that requires few or no stitches. The surgeon folds this type of lens and inserts it into the empty capsule where the natural lens used to be. Once inside the eye, the folded IOL unfolds, filling the empty capsule.

Some of the types of lenses available include:

Fixed-focus monofocal.This type of lens has a single focus strength for distance vision. Reading will generally require the use of reading glasses.These lenses are similar to glasses with bifocal or progressive lenses. Different areas of the lens have different focusing strengths, allowing for near, medium and far vision.Astigmatism correction (toric).If you have a significant astigmatism, a toric lens can help correct your distance vision.Discuss the benefits and risks of the different types of IOLs with your eye surgeon to determine what’s best for you.
