What is LASIK surgery?
LASIK surgery is an outpatient procedure in which the cornea is reshaped to reduce or eliminate the need for glasses or contact lenses in cases of nearsightedness, farsightedness, or astigmatism. LASIK is an acronym for LASer In-situ Keratomileusis. First a flap of corneal tissue is created and then folded back. Then the laser is used to reshape the inner portion of the cornea, thereby improving vision. The flap can be created using a mechanical microkeratome or the flap can be created using a laser - a procedure called "Intralase".
What is PRK?
PRK stands for photorefractive keratectomy. With PRK no flap is created. The excimer laser is used to reshape the surface of the cornea rather than the inner layer. PRK may be better for some patients who have large pupils, thin cornea, or dry eye. Vision improvement is slower with PRK so some persons have one eye done first, and the other one done about a month later. A bandage contact lens is usually worn for about a week following PRK to increase the comfort and speed that the cornea heals.
Am I a good candidate for Laser surgery?
Candidates should be at least 18 years of age and have a stable prescription for at least one year prior to undergoing laser surgery. Patients must have good ocular and general health, a correctable vision within a certain range, and enough corneal thickness to ensure safety. A complete eye examination and consultation will determine whether or not you are a suitable candidate for laser surgery.
Is it safe?
As with any surgical procedure, there is always a certain degree of risk. With laser surgery one to five percent of patients experience a complication, although most of these are minor and improve or resolve within 6-12 months or with retreatment.
Will laser surgery eliminate my need for glasses for the rest of my life?
Most persons will not need glasses after laser surgery until the age of 45 when most persons will need a correction for reading. Some persons will still require a slight correction after laser surgery.
