What is LASIK?

LASIK, or laser in situ keratomileusis, is a type of laser eye surgery used to correct some types of vision problems. LASIK vision correction can correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Refractive errors occur when the outer layer of the eye, the cornea, is misshapen. When the cornea is not curved correctly, it can interfere with the way light enters the eye and distorted vision can result. LASIK helps to correct refractive errors by reshaping the cornea. Patients who undergo LASIK usually do so to achieve clearer vision and reduce their need for eyeglasses or contact lenses.

The LASIK surgery procedure is fairly short; it often takes less than 30 minutes to perform. First, the surgeon numbs the eye with anesthetic drops. Then a special instrument called a microkeratome is used to cut a thin flap in the cornea. The surgeon carefully pulls the flap back to reveal the tissue beneath. A laser is then used to change the shape of the eye, correcting the refractive error. When the surgery is complete, the surgeon lays the corneal flap back in place. As the eye heals, the flap works as a sort of natural bandage.

LASIK offers patients many potential benefits, including better vision and a short LASIK recovery time. Like any surgical procedure, however, there are risks involved. Some patients experience bothersome side effects such as dryness, glare, or halos following surgery. For some, these symptoms never subside and may interfere with night driving and other activities. There is also a chance that your eyes could be corrected either too much or not enough. Permanent vision loss is rare.

The best way to determine whether LASIK eye surgery is right for you is to contact a well-qualified San Diego ophthalmologist..
