Is it painful?
There is little if any discomfort during
surgery because the cornea and eye are anesthetized by drops. Some patients
experience a "scratchy feeling." After the anesthetic wears off, the
amount of discomfort varies with each individual, but any irritation is minor
and usually disappears within a few hours. You may be sensitive to light for a
few days.
When will I be able to return to
work?
Most people can return to work one to
three days following surgery, but a rule of thumb is to wait until you feel up
to it. Most return to normal activities as soon as the day after surgery.
What are the side effects and
risks?
The most common side effects are a halo
effect and some glare at night around lights.
(See "What Are the
Risks of Laser Surgery?")
How long does the treatment
take?
Laser treatment itself takes only about
15 to 40 seconds, based on the degree of correction necessary. Recovery is
minimal, and usually the patient is able to be driven home after about 30
minutes. Typically, you will notice improved sight in 3 to 5 days following
treatment.
Is the treatment permanent?
According to the results of the U.S.
clinical trials and results reported internationally, the treatment appears to
be permanent. As people age, however, their eyes change and re-treatment may be
necessary.
Are there any activity
restrictions following surgery?
Following surgery, do not rub your eyes.
Other than that, patients can do whatever they feel up to as long as they follow
their doctors' instructions.
What if I move my head during
surgery?
This is the number one question that
patients ask when undergoing laser treatment. The surgeon is skilled in the
technique of removing his foot from the pedal that controls the ultraviolet beam
as soon as a patient moves his or her head. This allows him to realign the beam
with the corneal "target" and proceed with the surgery.
