A cataract
is a cloudy area in the natural lens of the eye.
The lens helps focus
light on the retina at the back of the eye. It is located behind the
iris (the colored part of the eye). As a cataract grows larger over
time, the cloudiness worsens and causes vision problems.
Most cataracts occur naturally as people get older, but could appear
earlier in life in cases of: eye injury, diabetes or other diseases,
exposure to radiation, especially x-rays, long-term use of steroid
medication, exposure to toxic substances, an inflammatory disorder of
the eye (iritis), prolonged exposure to sunlight.
Cataracts are bilateral, but one eye could be affected earlier than the
other.
The symptoms of a cataract include: blurred vision, a need for frequent
changes in eyeglasses or contacts, trouble driving at night because of
the glare caused by cataract, sensitivity to bright light, change in
color vision (yellow, orange, and red appear brighter and blue appears
dull).
Cataracts do not cause complete blindness. However, it is possible to
lose enough vision to be declared legally blind.
The symptoms of a cataract develop slowly and are painless. The
condition may go unnoticed and undiagnosed for a long time. It is often
first diagnosed during a routine eye exam.
If the cataract is affecting the vision and lifestyle and cannot be
helped with glasses or contact lenses, a surgeon may need to remove the
lens. This type of surgery is called cataract extraction surgery. An
artificial intraocular lens will replace the natural lens during
cataract surgery and will make you see well again.
Lasers are not used to remove cataracts. However, they may be used to
open a cloudy membrane that may develop after cataract surgery. We may
reduce the risk of damaging the eyes and in turn reduce the risk of
developing cataracts by wearing glasses with a UV coating that protects
the eyes from sunlight, and wearing goggles or safety glasses at work
or during recreation where your eyes could be injured.
