What is LASIK?
to the late 1970s, countless numbers of people were unable to
live the lives they wanted due to vision abnormalities. All of
this changed with the advent of refractive surgery. With the
invention of the excimer laser, patients no longer have to depend
upon glasses and contact lenses for vision correction. Refractive
surgery is helping people lead more active, carefree lives. For
many, Laser in-Situ Keratomileusis (LASIK) represents
the first step toward this goal.
LASIK surgery is a safe, modern procedure that utilizes
the precision of the excimer laser to improve vision. How effective
is the LASIK procedure? For many patients, LASIK
is overwhelmingly successful, allowing many to pass a driver's
test without the use of eyeglasses or corrective lenses. In a
small number of cases, an additional procedure may need to be
performed to fine-tune a patient's eyesight.
in-Situ Keratomileusis (LASIK)
the precision of the excimer laser, the LASIK procedure
reshapes the cornea, improving the eye's ability to refract light.
Dr. Burrell begins by sliding a microkeratome across the
cornea, folding back its outermost layer. The excimer laser then
sends gentle pulses of ultraviolet light to reshape the cornea.
This process takes approximately one minute, and is accurate
to within .25 microns. The excimer laser beam can be adjusted
to account for myopia (nearsightedness), hyperopia (farsightedness)
Once the cornea has been reshaped, its outermost layer is replaced.
Patients usually recover very quickly from a LASIK procedure
due to the cornea's extraordinary ability to heal. LASIK
is performed on an outpatient basis. The procedure takes minutes
to perform. Dr. Burrell insures a painless procedure by
using eye drops to numb the eye.
the procedure, patients may experience some mild discomfort,
although this is diminished through medication. The vast majority
of patients experience significant improvement in their sight
within the first 24 hours. A small percentage of patients may
have temporarily blurred or fluctuating vision. Patients can
usually return to work and resume their normal activities a day
after the surgery.
The Best Candidate
LASIK is ideal for
patients past the age of 21 who have healthy eyes and a stable
glasses prescription. The LASIK procedure should not be performed
on patients who suffer from certain medical conditions, or on
decision to undergo a LASIK procedure is a personal one.
Before undergoing LASIK, it is important to know the risks
involved, and to have realistic expectations. A LASIK
procedure can improve, but not perfect, your vision. Nor does
LASIK correct for presbyopia, an aging of the eye that
typically requires people to use reading glasses. Many patients
past the age of 40 may be required to wear reading glasses once
LASIK has been performed. Contact Dr. Burrell for
additional information on whether you are a good candidate for
the LASIK procedure.
will perform a free consultation to determine your level of refractive
error. If your refractive error falls within the parameters considered
appropriate for LASIK, more extensive tests will be performed.
If it is determined that you are not a candidate, you may still
be able to pursue other refractive procedures for vision correction.
commonly referred to as nearsightedness, is a condition whereby
light rays focus in front of the retina, instead of directly
on the retina.
farsightedness occurs when the eye is too small or the cornea
is too flat. When this happens, visual images are focused behind
