A cataract is a clouding that develops in the lens of the eye, occurring in
varying degrees of opacity. When a cataract develops, it begins to obscure the
light filtered to the lens, preventing the lens from focusing properly causing
Cataracts occur during the aging process when proteins in the lens
begin to clump together forming a cloud over the lens. While a cataract
begins as a small clump, you may feel your vision affected minimally.
One of the most common signs is a slight blurring in vision. As more
proteins begin to clump, the cataract grows making seeing difficult.
Other symptoms include a loss in contrast sensitivity so that shadows
and colors may appear less vivid.
Cataracts are classified as one of three types:
This cataract forms in the back of the lens and is most commonly
found in people with diabetes, intense farsightedness, and those taking
high steroid doses.
Nuclear cataracts are most commonly associated with the natural aging
process and form in the nucleus, the center of the lens. This type of
cataractís development can be seen over time.
Cortial cataracts form in the lens cortex and gradually extend from
the outside of the lens to the center. Diabetics are often as risk of
developing cortical cataracts.
Initial cataract treatment includes the use of glasses, bifocals
magnification or other visual aids. If cataracts develop enough to
visually impair you and negatively affect your daily life, consider
cataract surgery to improve your vision. During cataract surgery, your
surgeon will remove the clouded lens and replace it with a clear plastic
intraocular lens (IOL). Most cataract surgeries have a high success
rate, resulting in dramatically improved vision.
