Before the surgery, your surgeon should explain to you
the risks and possible complications, and potential side
effects, including the pros and cons of having one or both
eyes done on the same day.

The Risk of LASIK and Possible Complications
This is the "informed consent" process. Some risks and possible complications include:
|
| • |
Over - or under - correction. These problems can often be improved
with glasses, contact lenses and enhancements.
|
| • |
Corneal scarring, irregular astigmatism (permanent warping
of the cornea), and an inability to wear contact lenses.
|
| • |
Corneal infection.
|
| • |
"Loss of best corrected visual acuity" - that is,
you would not be able to see as well after surgery,
even with glasses or contacts, as you did with glasses
or contacts before surgery.
|
| • |
A decrease in contrast sensitivity, "crispness,"
or sharpness. That means that even though you may
have 20/20 vision, objects may appear fuzzy or grayish.
|
| • |
Problems with night driving that may require glasses.
|
| • |
Flap problems, including: irregular flaps, incomplete flaps,
flaps cut off entirely, and ingrowth of cells under the flap.
The following side effects are possible, but usually disappear
over time. In rare situations, they may be permanent.
|
| • |
Discomfort or pain
|
| • |
Hazy or blurry vision
|
| • |
Scratchiness
|
| • |
Dryness
|
| • |
Glare
|
| • |
Haloes or starbursts around lights
|
| • |
Light sensitivity
|
| • |
Small pink or red patches on the white of the eye

Stop or Continue for LASIK survery ?
Most patients are very pleased with the results of their
refractive surgery. However, like any other medical procedure,
there are risks involved. That's why it is important for you to
understand the limitations and possible complications of
refractive surgery.
Before undergoing a refractive procedure, you should carefully
weigh the risks and benefits based on your own personal value system,
and try to avoid being influenced by friends that have had the procedure
or doctors encouraging you to do so.
BENEFIT of LASIK
In spite of the risks associated with LASIK,
there are several advantages to having the procedure done:
|
|
| • |
Glasses or contact lenses will be unnecessary
|
| • |
Any discomfort with contact lenses will be eliminated
|
| • |
Quality of vision is usually better than that achieved
with glasses or contact lenses
|
| • |
As most patients achieve 20/40 vision or better,
you will be able to pass a driver's test without wearing
glasses or contact lenses
