Described as a natural clouding of the eye lens, cataracts are pretty common. Cataracts are actually considered an inevitable part of aging and are widespread among people ages 55 years and older. In fact, half of all Americans have them — or have had cataract surgery — by age 80. In other words, if you live long enough, you will likely develop cataracts.
What's worse, if left untreated, cataracts can lead to blindness. Cataracts are already the leading cause of vision loss in adults over age 55 and the most common cause behind blindness worldwide.
The good news, however, is that treatment for cataracts is successful; more than 97 percent of the 3 million-plus cataract surgeries performed each year in the United States are considered successful.
In fact, about 95 percent of patients are able to restore their full pre-cataract distance vision after undergoing the standard intraocular lens (IOL) procedure.
