A cataract is an opacity or clouding of the crystalline lens that may develop as a result of aging, some medications such as steroids, metabolic disorders like diabetes, trauma, or heredity. Cataracts typically develop slowly and progressively, causing a gradual and painless decrease in vision. Things can look blurry, hazy, or even less colorful.

Reducing one’s exposure to ultraviolet light by wearing a wide-brimmed hat and sunglasses may reduce the risk of developing a cataract, but, once one has developed, there is no cure except to have the cataract surgically removed.

The only effective treatment for cataracts is the surgical removal of the cloudy lens. With a single outpatient surgical procedure, an ophthalmologist can remove the cataract through a small, self-sealing incision. Usually, a synthetic intraocular lens is inserted at the time of cataract extraction to replace the focusing power of the natural lens. The time to have cataract surgery is when the cataract is affecting one’s vision enough to interfere with normal daily activities.

Cataract surgery is a very common and successful operation. 3.5 million people have this procedure every year and it is one of the most common surgeries in the United States. When you visit Ophthalmology Associates, a series of tests will be performed so your doctor can customize a treatment plan to match your eye and your goals.
