| LASIK laser eye surgery is a procedure where the shape of
the cornea is permanently changed to reduce reliance on glasses
or contacts. In a large percentage of cases the patient will end
up with 20/20 vision even after having a very strong glasses or
contacts prescription. Note: as with any medical procedure
different patients and different doctors will have different
needs. Never make a decision based on the information you see
here. Always consult a doctor to help make any decisions.
LASIK is short for Laser-Assisted in Situ Keratomileusis and
is a procedure to change the shape of the cornea using a excimer
laser. A knife is used to cut a flap in the cornea. The flap is
then folded back revealing the stroma. Then a computer
controlled laser is used to vaporize a small portion of the
stroma and the flap is replaced. Now the cornea is a different
shape and will focus light onto the correct portion of the
retina allowing for clearer vision.
What are some of the risks associated with LASIK laser eye
surgery?
- Some patients lose vision. Sometimes patients will
lose lines of vision. This vision can not be corrected with
glasses or contacts.
- Over or under correction. Some patients will not
achieve 20/20 vision and will need further surgery to make
corrections. Or in some cases no further surgery can be
performed and the patient will continue to need glasses or
contacts.
- Severe dry eyes. Some patients develop dry eyes and
need eye drops to keep from having pain. For many this will go
away after several months. But for some, especially those with
dry eye problems before the surgery it will be permanent. In
very sever cases the patient will need eye drops every few
minutes to keep from being in pain.
- Visual abnormalities. Again some patients will have
some visual abnormalities. Most commonly a "glare halo" or
circles around lights in your vision will occur causing vision
to be negatively impacted. Also occasionally double vision can
occur.
- Finally it is still a new technology. The first FDA
approved LASIK laser was approved in 1998, so long term
effects of LASIK can not yet be known.
So knowing that what percentage of patients have
complications? Many doctors who do careful screening of there
patients find that they have less than 1% of patients with
complications. So be sure to find a good doctor who will
honestly evaluate your particular situation and evaluate whether
you are a good candidate for the surgery. For more info on
