What is LASIK?

LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A knife, called a microkeratome, is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middlesection of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced.

As with any surgery, there are risks when undergoing LASIK. There is a possibility that you could be under-treated or over-treated, requiring additional treatment or the need for glasses or contacts after surgery. In addition, there is a risk of developing dry eye, glare, or halos with night vision, and in rare cases, permanent vision loss.

Since LASIK is surgery, it is important that you choose your doctor with care. Extensive research and visits to several ophthalmologists are recommended.

This information is intended to provide a brief overview of LASIK. Contact a qualified ophthalmologist for more information specific to your case.
