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.
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.

There are 20.5 million
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)
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) |
