Laser in-situ keratomileusis (LASIK) is the preferred
procedure for correcting
farsightedness (hyperopia). It changes the shape of the eye. In LASIK, a thin flap is
made on the cornea using a blade or laser. The flap is lifted, and a laser is
applied to the central corneal tissue. The laser makes contact with the
cornea in a circular pattern around the central
optical zone. This changes the profile of the cornea, making it steeper. The
laser removes tissue from the cornea very precisely without damaging nearby
tissues. The flap is then replaced, allowing for rapid healing.
LASIK is performed in a surgeon's office or same-day surgery
center. It does not require a hospital stay.
This procedure may not be available in all areas, but it is done in
most large cities.
Most people have little or no pain after LASIK surgery. And most people who have LASIK see quite well the next day.
Your doctor will want you to come in for an exam the day after the
surgery and for regular follow-up exams for about 6 months.
After LASIK surgery to correct farsightedness:
LASIK surgery may be used to correct mild to moderate
farsightedness. Treating severe farsightedness is not as effective as treating
mild or moderate farsightedness.
LASIK is an elective, cosmetic procedure, done to correct
farsightedness in otherwise healthy eyes.
The procedure may not be done for people who:1
LASIK is a relatively new surgery. (It was approved by the U.S.
Food and Drug Administration in 2000.) Little is known about the long-term
outcomes. Doctors continue to improve the technique and to study the long-term
Over the short term, LASIK has been shown to be effective and
consistent in reducing mild to moderate farsightedness.
LASIK is better at treating lower levels of farsightedness than
The risk of complications from LASIK surgery is low, and it
decreases even further with a more experienced surgeon. Look for a corneal
specialist or surgeon who does this surgery frequently.
Complications and side effects from LASIK may include:
Serious vision-threatening complications are rare but may
Because LASIK is a relatively new procedure, long-term risks are
not yet known.
If you are thinking about having surgery to improve farsightedness, discuss
the different options (LASIK, PRK, LASEK, intraocular lens implants, CK, and LTK)
with your doctor. LASIK is the refractive surgery of choice
for most people.
Be sure to keep a record of your original eye
measurements from this procedure (your doctor can give them to you), in case
you need cataract surgery in the future. This record can help your doctor calculate the
power of future post-cataract implants.
LASIK is a cosmetic procedure. The cost of refractive surgery
insurance companies do not cover the cost of refractive surgery.
