Laser Vision Correction
WHAT IS LASIK SURGERY?
A LASIK surgery procedure is
designed to reduce or eliminate the need for glasses or contacts. An excimer
laser gently reshapes the cornea with computer-controlled precision to correct
nearsightedness, farsightedness and astigmatism. To be considered a candidate,
you must be at least 18 years old, have healthy eyes and a stable eye
prescription for the last twelve months.
IS LASIK A SAFE PROCEDURE?
Since being FDA approved in 1995,
laser vision correction surgery complications are very rare today. Although
LASIK surgeons can provide you with the potential outcome of your surgery, no
surgeon can guarantee a specific visual acuity. In making the decision to
undergo LASIK surgery, be sure to have a list of questions to ask about the
procedure. Those with certain medical conditions and women who are pregnant or
nursing (within the last 3 months) are not candidates.
IS THE LASIK PROCEDURE PAINFUL?
Many patients are surprised to
not feel any pain with their LASIK surgery. Prior to surgery you may be given a
mild sedative to help you relax. Anesthetic drops are used to numb the eye
before LASIK eye surgery begins and during the laser correction you may feel a
light pressure sensation. After your procedure, your eye may feel a bit
irritated for a few hours and most patients are quite comfortable after taking
a short nap. You will be prescribed drops for your eyes to provide comfort and
healing in the days following your surgery.
HOW SOON AFTER LASIK SURGERY CAN
I RESUME NORMAL ACTIVITIES?
There are minimal restrictions in
the first weeks following LASIK. Many patients are able to resume normal
activities the following day. Vision results from LASIK can vary, but most
patients are able to see clearly 24-48 hours after surgery. Further vision
improvement may continue over several months. Your doctor will recommend
avoiding certain activities, like swimming or contact sports for several weeks.
HOW DOES PRK COMPARE TO LASIK?
PRK and LASIK surgery have
comparable results and your doctor can discuss which is most appropriate for
your condition during your evaluation. A major difference is LASIK surgery
creates a hinged flap on the cornea. LASIK patients report minimal irritation
and their vision stabilizes more quickly than PRK. PRK involves treating the
surface of the cornea. PRK recovery takes a few days with hazy vision and some
discomfort. It is often recommended when the patient’s cornea is too thin for
HOW LONG WILL VISION CORRECTION
Your distance vision is fairly
permanent following laser vision correction. The goal of laser vision
correction is to reduce or eliminate your dependence on glasses and contact
lenses. The need for reading glasses is a normal age related change and laser
vision correction does not change this.
WHAT WILL HAPPEN DURING MY LASIK
Plan to be at doctor’s office for
approximately 2-3 hours for the exam and special testing used to measure and
evaluate your eyes. If you wear contacts, prior to your scheduled evaluation,
you may be asked to refrain from wearing contact lenses for a specified period
of time. Your eyes may be dilated in preparation of a detailed eye exam that
will evaluate refractive error, pupil size and corneal evaluations. There will
be a thorough discussion of LASIK eye surgery and whether or not you may be a
WHAT ARE THE SIDE EFFECTS AND
RISKS WITH LASIK OR PRK SURGERY?
Temporary side effects following
laser vision correction can include dryness of eyes, sensitivity to light or
halos at night. Glares or halos at night usually resolve within a few weeks.
Night vision disturbances associated with imperfections in the eye prior to
LASIK are now able to be reduced with the Custom Wavefront technology. During
the healing process, dry eyes can be treated by using artificial tears. As with
other elective procedures, individual results may vary.
