    How Are Cataracts Treated? continued...

    Cataract surgery is usually done on an outpatient basis and is very successful in restoring vision. The surgeon removes your lens and replaces it with a clear artificial one. It is the most frequently performed surgery in the U.S., with more than 1.5 million cataract surgeries done each year. More than 90% of the people who have cataract surgery have better vision.

    Talk to your doctor to see which treatment is right for you.

    Can Cataracts Be Prevented?

    Because the exact cause of cataracts is uncertain, there is no proven way to prevent them. Because cataracts and other conditions such as glaucoma are common in older adults, it's important to have your eyes examined regularly.

    This is particularly important if you have risk factors or a family history of eye problems. Adults should see an eye doctor at least every 2 years until age 50 and yearly after age 50.

    People with a history of eye problems or other medical conditions that increase the risk of eye disease, such as diabetes, may need eye exams more often.

    Be sure to ask your doctor if you have any risk factors or signs that cataracts or other conditions may affect your vision.
