How Safe is Laser Eye Surgery?
Tired of hunting around for those pesky lost spectacles? Well
laser eye surgery might be the answer to your problem because it
can rectify visual defects rapidly and easily.
There are two different types of corrective eye surgery by use
of laser, PRK and LASIK. PRK differs from the latter because it
involves a surface ablation procedure. This technique removes
the outer layer of the cornea, or epithelium. Think of it rather
as scraping away the outer layer of cells, rather like hosing
away leaves on an autumn day. In LASIK, on the other hand, the
laser is used to cut a flap in the cornea. These techniques
might make it easier to read the newspaper of search for those
missing car keys,
but they might not suit everybody! So before embarking on
what might be an expensive bout of surgery that causes you risky
complications it pays to ask your ophthalmologist a number of
searching questions, and don't let the specialist get away with
it if you receive a series of evasive answers.
First you need to know how effective your eye doctor thinks the
procedure will be in your own particular case. Then how accurate
will the re-shaping, or mapping of the eyeball be. You always
want a global figure that will probably be a percentage of the
number of patients who have undergone corrective eye surgery
without having to resort to a second or subsequent intervention.
In other words you want to be re-assured that the surgeon can
get it right the first time. Of course another key question is
whether or not there are side effects and what these could be.
If your eye specialist is up to speed, you will have a body of
evidence at your finger tips to help you make the decision of
whether to proceed or not.
How effective is laser eye surgery? Sometimes expectations are
not met as people can experience a halo effect, find glare
particularly disturbing and lose the ability to see clearly in
the dark. All of that can have serious effects on night driving
for example! Moreover, experts note that 20/20 vision from laser
corrected surgery may differ considerably from that experienced
by the use of corrective lenses. Sometimes it might just be
better and simpler to stick with the eyeglasses.
However, like everything in life you get what you pay for. It
seems the more expensive the technique the less likelihood there
is of risk and possible side effects. So the best advice one can
give for those considering corrective eye surgery by laser is to
research the subject extensively before embarking on the
treatment and don't skimp on the cost!
