A cataract is a clouding of the natural
lens the part of the eye responsible for focusing light and producing clear, sharp images. The lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, the cells accumulate causing the lens to cloud, making images look blurred or fuzzy. For most people, cataracts are a natural result of aging.

Cataracts are the leading cause of visual loss among adults 55 and older. Eye injuries, certain medications, and diseases such as diabetes and alcoholism have also been known to cause cataracts.

Is cataract surgery effective?
Cataract removal is one of the most common operations performed in the U.S. today. It is also one of the safest and most effective. In about 90 percent of cases, people who have cataract surgery have better vision afterward.

While total blindness due to
cataracts has been virtually eliminated in the developed world, in places with intense ultraviolet exposure, poor diet, and lack of clean water, cataracts cripple almost 69 million people annually and often progress to the point where they block all vision.
