What is a Cataract?
With the formation of a cataract, activities like reading, bowling, or
driving can be difficult. Fortunately, vision can be restored quickly,
allowing the patient to return home within a few hours. With new
advances in cataract surgery, vision improvement begins almost
immediately, and an eye patch isn't even needed.

So What is a
Cataract? A Cataract is the clouding of the lens of the eye.
(See above animation) Normally, light passes through the clear lens and
is focused onto the Retina. However, the natural aging process can cause
the lens to become cloudy. The Cataract or cloudy lens blocks the
passage of light through the eye and causes distorted or blurred vision,
glare, or difficulty seeing in poor lighting conditions.
Cataract
surgery is the most common operation in the world. In the United States,
more than 2.7 million procedures are performed annually. (National
Institutes of Health)
There are many millions of cases of early cataracts among
Americans aged 40 and older, and 50 percent of people older than 65 have
developed significant cataracts. (National Institutes of Health) |
