What is a cataract?

a clear lens and a cataract, Dr Ahmad Khalil Eye Clinic, Cairo, Egypt

 In a normal eye, the lens - which lies behind the pupil - is clear (transparent), so the pupil appears black. In an eye with a severe cataract, the cataract clouds the lens, so that the pupil appears gray or cloudy.


A cataract is a cloudiness that develops inside the lens of the eye. The cloud blocks the light passing through the lens, which impairs your vision. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car — especially at night — or see the expression on a friend's face.

The lens is held inside a capsule located just behind the pupil and the colored iris. It is made up of protein fibers and water molecules that are arranged exactly to allow light to pass through without interference. Cataracts occur when these fibers begin to split over time, clustering together and clouding the lens. As fibers continue to break down, the clouding becomes more and more dense and covers a larger part of the lens.

To distinguished Genius, Prof Dr Ahmad Khalil

Please accept my sincere thanks for your proper medical care of my condition. I came to you with diabetic eye disease, and cataracts, and glaucoma. I have diabetes for over 47 years. But because of your distinguished care of my condition in the past 3 years, my chronic diseases have been controlled, and thanks to your dextrous hands, you performed my cataract operations, and I could resume my favorite hobby of reading, and I could go back to driving my car again. I repeat my thanks to you for your total care of my eye conditions.


A cloudy lens can be the result of drugs or chemical exposure, trauma, radiation, heredity, or simply related to the aging process. Cataracts can also occur at birth. A cataract is NOT a growth, NOT a film, and NOT a tumor. When the cloudy lens reaches a certain point, we simply stop calling it a lens and start calling it a cataract.


the need for cataract surgery

When cataract or lens opacity are significant enough to interfere with your daily activities, then it needs to be removed. Small incision PHACO surgery and foldable (soft) lens implantation (including the new multifocal lenses) is currently the best recognised procedure for the management of cataract. This is done by Dr Khalil in some of the best centers in Cairo, and patients get out of the hospital in the same day.
