LASIK: Frequently Asked Questions
1. What is LASIK laser vision correction?
It is a surgical procedure that uses a cool (non-thermal)
beam of light to gently reshape the cornea - the surface
of the eye - to improve vision. The laser removes microscopic bits of
tissue to flatten the cornea (for nearsightedness), steepen the
cornea (for farsightedness), and/or smooth out corneal irregularities (for astigmatism). The goal is to shape the cornea so it does a better job of focusing images onto the retina, for sharper vision.
2. Is LASIK safe?
The FDA recognizes LASIK as proven, safe and effective. Laser vision correction uses a cool (non-thermal) beam of light that is computer controlled. The surgeon turns the laser on and is able to turn it off at any moment. There are many safeguards in place to reduce the risk of error. However, there are risks associated with any surgical procedure.
Although no one knows the exact number of complications, studies suggest that the incidence of minor difficulties such as dry eyes and nighttime glare is around 3% to 5%, while the risk of serious incidents such as lost vision is thought to be less than 1%. There are no known cases of blindness from LASIK.
3. Can I have both eyes done at the same time?
Yes, most surgeons perform the procedure on both eyes at the same time.
4. How is eye laser surgery different from previous types of refractive eye surgery?
Current FDA-approved laser vision correction methods, such as LASIK (Laser-assisted in situ keratomileusis), have a higher predictability of the final result with a lower incidence of complications. Additionally, older techniques typically involved manually performed incisions rather than automated lasers for correction.
5. Does laser vision correction hurt?
You won't feel pain during LASIK, because your surgeon will place anesthetic drops in your eye first. Afterward, he or she may prescribe medication if necessary. Many LASIK patients report no more than mild discomfort for a day or so - often it's itchy feeling, as if sand were in the eye.
