What are Cataracts?

Q: I am 54 years old and my vision has really deteriorated over the last year or so. I was told that I may have cataracts. Can you tell me a little bit about them, what they are and if I have them, What are my options? I am concerned.

A: Cataracts

The lens of your eye works much like a lens of a camera. Made mostly of protein and water, the lens focuses light images onto the retina, where signals are converted and signals are then sent onto the brain. Cataracts, a clouding of the natural lens can keep light and images from reaching the retina. Sharp images become blurry, bright colors become dull and seeing at night can become much more difficult. Cataracts can be caused by eye injury, diseases, chemicals or medications, but 90% of the cases are caused by the simple process of aging. More than 50% of people over the age of 60, as well as many younger than that suffer from this ailment. There is no medical treatment to reverse or prevent the development of cataracts. The best way to treat a cataract is to remove the old, clouded lens, and replace or exchange it with a new clear one.

In 1949, Intra-Ocular Lens or IOL’s were first introduced. These lenses were of a “single-vision” type, meaning that they could correct for middle or distance vision, but patients probably would still need glasses for full range vision such as reading or middle distance vision. Cataract surgery was considered risky and required a lengthy hospital stay.

Cataract surgery has undergone tremendous technological advances since the days of your parents and grandparents. IOL’s are still used very successfully today, but the advances in surgery, lens and visual quality as well as patient satisfaction have increased tremendously.

At the Khanna Institute of LASIK & Refractive Surgery, Rajesh Khanna, MD is an internationally recognized cataract surgeon and has been noted for his skills and use of ultra-small incisions which measure less than 1 mm in diameter. Dr. Khanna has been using the latest generation IOL’s, such as the Acrysof ReSTOR lens that rely on advanced multi-focal technology that allow patients to see both near and far objects without glasses! In a clinical study, 80% of patients receiving the ReSTOR lens reported that they no longer wore glasses for any activities at all. Dr. Khanna has found that combing these new lenses with the small incision procedure, there is no need for stitches, can provide reduced healing time and thereby significantly increases patient comfort.

If you suspect the development of cataracts and would like more information on the lens replacement procedure or the multi-focal lens, you can contact the Khanna Institute at 877-2-KHANNA or on the web at /cataracts.html
