A cataract is a cloudy lens of the eye. The lens of the eye focuses light. It is located behind the iris, or the round colored portion of the eye. It is disc-shaped and looks like a small, flat, clear marble. When the eye ages, the proteins that make up the lens change causing the lens to become cloudy. When this occurs, the cloudy lens becomes what is called a cataract. As we age, everyone eventually develops a cataract in each eye. Some people may not have much trouble with their sight, others may have debilitating vision loss. Most patients complain that their vision has become cloudy, fuzzy, or that colors appear dimmer. Many will complain of halos around lights. Fortunately, cataract surgery with intraocular lens implantation can reverse the visual problems.
