More than 4.2 million cataract surgeries are performed each year in the United States.
A cataract is a clouding of the lens inside the eye. Presently, there is no way to eliminate a cataract other than surgically removing it. Cataracts are most commonly found in people aged sixty and over. They are usually a result of the natural aging process of the eye.
However, cataracts can also be diagnosed in much younger patients. They can be the result of previous eye injury, chronic steroid use, or they may be inherited. Excessive ultraviolet light exposure, cigarette smoking, and certain medications are also considered risk factors for cataract development.
Currently, there are no proven methods of preventing cataracts. As you can see in this picture, the eye with the cataract looks very clouded, resulting in poor vision. The normal eye is clear, allowing for excellent vision.
More than 95% of patients will obtain a substantial improvement in vision after surgery. Fortunately, the chances of problems after surgery, such as infection or bleeding, are less than 1%.
