A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. It happens when protein builds up in the lens of the eye, making it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. Cataracts are the most common cause of vision loss in people over age 40 and are the principal cause of blindness in the world.
HOW IS CATARACT DIAGNOSED?
The ophthalmologist will get an eye exam to test how well the patient is able to see. The doctor may dilate the pupil of the eye to examine the lens and other parts of the eye.
HOW IS CATARACT TREATED?
Usually, the ophthalmologist will prescribe medication and surgery for cataract removal so as to prevent the risk of permanent vision impairment. Eye glasses and lens can also help promote better vision for cases that not too severe.
