 If
you or anyone you know has cataracts, it
would be good for you to keep reading on.
This article is going to help you
understand what cataracts are and what
options a cataract patient has in terms of
surgery.
So what is cataract? Cataract affects
the lens of the eye causing clouding of
the vision. Once cataract has set in,
light is scattered or is fully or
partially blocked out. This clouding
impairs the vision of the person with
cataract.
Though cataract is an abnormality in
vision, it is a normal occurrence in
aging. More than 90% persons older than 75
years old have cataract. Most of the time,
cataract affects both eyes but one eye is
more affected than the other.

Cataract symptoms may be minimal so
that persons affected may not even be
aware of it. However, severe cataracts
cannot see good enough to function
normally in their daily lives.
How do you know if you have cataracts?
One of the telltale signs that you are
starting
to
have cataracts is having foggy, fuzzy,
cloudy or filmy vision. There may also be
changes in color vision. Night driving
becomes difficult because headlights seem
glaring. So are lamps and sunshine. Double
vision also becomes a problem.
How can cataract be treated? The most
common way is to change glasses with
magnifying lenses and stronger bifocals.
But if this method is not enough, surgery
maybe required. The treatment will be
undergone by removing the eye lens and
replacing it with artificial lenses known
as implant.
Cataract can also be removed through
surgery but it will not be immediately
done. An eye examination will be needed
once you're very uncomfortable with your
eye vision. Your doctor will have to
explain the different options of surgery
and how you can prepare yourself.

Laser surgery is one way of removing
cataracts. Laser surgery for cataract is
still experimentally tested. It utilizes
light instead of ultrasound in dissolving
cataract. LASEK and LASIK processes fall
in laser surgery category.
In LASEK or laser epithelial
keratomileusis, the cornea's surface layer
will be treated with alcohol and peeled
back to reshape the layer underneath. The
process prevents complications associated
with cataract.

 In
LASIK or laser in situ
keratomileusis, the surface layer
of cornea is scoured away. This
is done to reshape the underlying
cornea surface.
LASIK began in the
mid-nineties and has largely
replaced the old process of PRK
or photorefractive keratectomy
since then. With LASIK, a flap is
created on top layer of the
cornea to allow access to
underlying surface of cornea.
LASIK prevents most problems
of postoperative pain, slow
rehabilitation and corneal haze
which are seen in the traditional
PRK.
Both LASEK and LASIK
procedures seem effective,
predictable and safe for also
treating low to moderate near
sightedness or myopia. Cataract
laser surgery is not performed in
the doctor's clinic because it
still needs surgical incision
requiring an opening in the
eyes.
