GET THE CLEAR PICTURE!For many years, the
only way to correct refractive errors or focusing
problems was with glasses or contact lenses. Recent
advances have now made it possible to surgically
alter the eye's refractive power to eliminate or
lessen the need for glasses or contact lenses. There
are several types of procedures to accomplish this,
some old, some new and some soon to be available in
the future.What is refractive
surgery or Laser Vision Correction?
Laser Vision Correction is a revolutionary medical
procedure that allows most people freedom from
glasses or contact lenses. A cool beam of laser
light microscopically reshapes the front contour of
the eye, the cornea, improving its focus. LASIK
is the technical name of the most common Laser
Vision Correction procedure used in recent years.
PRK is another type of Laser Vision Correction
and is very similar
What types of vision conditions can be improved?
LASIK can benefit most people with
nearsightedness (myopia), farsightedness (hyperopia),
and astigmatism. One of the major functions of the
front surface of the eye, or
cornea, is to focus light. Nearsightedness,
or
myopia, occurs when your eye is too long in
relation to the curvature of your cornea. Things are
better seen close up than at a distance.
Farsightedness, or
hyperopia, occurs when your eye is too short
in relation to the curvature of your cornea. Things
are better seen at a distance than near.
Astigmatism
exists when your cornea has an irregular, oval shape
and the focus is twisted. Laser Vision Correction,
or LASIK, is not able to remove cataracts,
correct presbyopia, or treat a lazy eye.
What is LASIK?
The most commonly performed refractive surgery is
called LASIK. With LASIK, a very thin flap is made
in the corneal surface with an instrument called a
microkeratome. After the flap is made, the exposed
cornea is treated with a cool laser beam, called
excimer laser. A small amount of tissue is sculpted
away, less than the thickness of thin hair. The flap
is then replaced. Healing occurs quickly and there
is typically little discomfort. This procedure
alters the curvature of the eye microscopically to
improve your focus.
What is PRK?
PRK is a close cousin to the technique of LASIK,
except that no flap of tissue is created on the
cornea. Healing takes a little longer and there is
some discomfort during the recovery stages of the
procedure. For this reason, many people prefer to
have LASIK instead
What is laser thermokeratoplasty and how it
used?
Laser thermokeratoplasty (LTK) is used for the
correction of hyperopia, or “farsightedness.” The
laser apparatus utilized does not touch the eye. It
causes the corneal tissue to shrink microscopically
which steepens the eye causing better near and
distance focusing.
Is Laser Vision Correction safe?
LASIK has been performed internationally for over 15
years and in U.S. clinical trials with excellent
results since 1995. Millions of patients worldwide
have undergone successful Laser Vision Correction
procedures. There is minimal risk of serious
complications. Most of the complications are
relatively mild and do not result in long-term
interference with vision. The complication rate
cited in large studies is between 0.5% and 1.9% at
1-2 years. Dr. Jones or Dr. Serdahl will thoroughly
discuss potential complications with any patient
considering LASIK.
Does insurance cover this surgery?
Although LASIK is not a cosmetic procedure, it is
considered an elective surgery. Most insurance
policies will not cover the procedure; although you
should check with your insurance company to see if
your policy offers partial or full coverage. Some
insurance companies will offer a discount and our
office will honor those arrangements In many cases,
the cost of the procedure can be covered by employer
medical flex plans or medical cafeteria plans that
allow pretax dollars to be set aside for medical
expenses. It is possible that the cost of LASIK may
be deducted from your federal income taxes.
How do I know if I am a candidate
for refractive surgery?
The decision to have refractive surgery, or any
elective procedure, should be made after a thorough
investigation of the benefits and risks and a
candid, honest and complete examination by either
ophthalmologist Dr. Jones or Dr. Serdahl. Please
