The
Truth about Cataracts
August is Cataract Awareness Month
Some
say if we live long enough, most of us will develop a cataract.
Yes, that may be true (one in seven people has a cataract). But
luckily, cataracts are also one of the most curable causes of vision
loss.
Celebrating
Cataract Awareness Month, throughout the month of August, Virginia's
EyeMDs want to dismiss a few myths about this common problem, and
to remind people they don't have to live with vision loss from cataracts.
A
cataract is the clouding of the eye's normally clear lens, which
blocks the passage of light needed for vision. They form slowly
and cause no pain. Some stay small and don't affect vision very
much, but if it does become large, thick or affects your vision,
it usually can be removed by surgery.
Cataracts
are one of the leading causes of blindness around the world; however
in most cases, vision loss from cataracts is reversible. New techniques
developed over the past decade have made cataract surgery one of
the most successful procedures available in terms of restoring quality
of life to patients.
There
are no drugs or exercises that will make a cataract disappear, and
contrary to popular myth, cataracts are not removed using lasers.
Cataract surgery is most often done as an outpatient procedure under
local anesthesia. The patient generally goes home the same day,
and because the incision is so small, many patients don't even need
stitches. The cloudy natural lens can be replaced with an artificial
lens to give the eye proper focusing power. In most cases, the improvement
in the patient's vision is profound. For some of them, it really
is like a miracle.
So
how do you know if you have a cataract? Some people notice a gradual
painless blurring of vision, double vision in one eye or fading
or yellowing of colors. When older patients mention sensitivity
to glare and/or bright light or trouble driving at night, a cataract
is suspect. Or, if a patient needs frequent changes to his or her
glasses or contact lens prescriptions, they should be evaluated
for a cataract.
The
Virginia Society of Ophthalmology wants to dispel the notion that
a cataract has to be "ripe" before it's removed. That's
just not true. The best time to have a cataract removed is when
it starts to interfere with the things you like to do.
It's
a great procedure, but it's still surgery. For some people, cataracts
don't particularly affect their quality of life, so for them it
makes sense to put off any cataract surgery until they feel they
need it. The only person who can really decide when it's time to
have it removed is the patient.
