Thinking
About Having Lasik? Things You Need To Consider First
You expect perfect results. Thousands of people have had excellent
results
from LASIK
surgery, but there is a slim margin of error in all operations
and
because LASIK
is relatively new, there is no long-term data reflecting
percentages
for accuracy or complications.
It will affect
your job. Some professional associations and divisions of the
military
do not support refractive procedures. For your sake, approve the
operation
with your employer before making an appointment for LASIK.
You cannot afford
the procedure without insurance. While LASIK is gaining
recognition,
most insurance packages still do not cover refractive surgery.
You have a refractive
instability. A refractive instability means that your
eyes ability
to focus light is still changing. This is usually caused by: age,
hormones,
a chronic disease like diabetes, or some medications. Some
refractive
instabilities are temporary, so be sure to discuss your options
with
a doctor.
Your immune
system is compromised. Some diseases, conditions, or
medications
that affect your immune system may prevent your eyes from
healing properly
after surgery.
You are an athlete
that may receive blows to the face. In some contact and
combat sports,
you have a higher risk of being struck on or around the eyes.
This type
of injury could alter the results of your refractive surgery.
You are under
18. Because of associated risks and the earlier mentioned
condition
of refractive instability, this procedure is not approved for
minors.
Again, because long-term statistics are not yet available on LASIK
eye surgery, there are some conditions that may or may not increase
your risk of complications. Ask your doctor for a referral if
you have: a strain of Herpes that has infected the skin around
your eyes; glaucoma, a risk of developing glaucoma, or hypertension
of the eyes; eye diseases that cause inflammation (like iritis
or uveitis); eye injuries with residual damage; previous eye surgery;
or Keratoconus (a degenerative form of astigmatism).
Other Considerations
Some complications are believed to be associated with the following
conditions. Consult your doctor if you have:
Blepharitis.
This condition is characterized by inflammation of the eyelids
and
may agitate
your eyes post-operation, increasing your chances of
developing
an infection.
Large pupils.
LASIK has been perfected for eyes with average pupils. Thus
the entire
pupil may not get treated on patients with abnormally large pupils.
This can
cause serious refractory disorders leading to visual aberrations
like
glare, starbursts,
and multiple images. This may be dangerous and
debilitating
in certain light and weather conditions.
Thin Corneas.
Again, refractive surgery demonstrates the best results in
patients
with eyes of average proportion and construction. Because the
procedure
works by reshaping the cornea of the eye, a thin cornea may
complicate
the procedure.
Previous eye
surgeries. If you have tried refractive surgery before, your 
doctor may
not approve a second surgery. It is possible that you have
refractory
instabilities or another condition that will affect your vision
even
after the
second surgery.
Keratitis or
KCS. Keratoconjunctivitis sicca is the scientific term for dry
eyes. LASIK
surgery may exacerbate your condition.
