If you're tired of wearing eyeglasses or contact lenses, you may wonder whether laser-assisted in-situ keratomileusis (LASIK) surgery is right for you. After all, LASIK surgery has a good track record and most people are satisfied with the results.
However, LASIK surgery isn't the most appropriate vision-correction option for everyone, and it's not without risks. Read on to determine whether you're a good candidate for LASIK surgery.
When is LASIK surgery a good choice?
LASIK surgery is a type of refractive eye surgery. During the procedure, an eye surgeon creates a flap in the cornea, and then uses a laser to reshape the cornea and correct focusing problems in the eye. LASIK surgery is most appropriate for people who have a moderate degree of:
Nearsightedness (myopia), in which you see nearby objects clearly, but distant objects are blurry
Farsightedness (hyperopia), in which you can see distant objects clearly, but nearby objects are blurry
Astigmatism, which causes overall blurry vision
A good surgical outcome depends on careful evaluation of your eyes before the surgery.
What are the risks of LASIK surgery?
As with any surgery, LASIK surgery carries risks, including:
Undercorrection, overcorrection or astigmatism. If the laser removes too little or too much tissue from your eye, you won't get the clearer vision you wanted. Similarly, uneven tissue removal can result in astigmatism.
Vision disturbances. After surgery you may have difficulty seeing at night. You might notice glare, halos around bright lights or double vision.
Dry eyes. LASIK surgery causes a temporary decrease in tear production. As your eyes heal, they might feel unusually dry.
Flap problems. Folding back or removing the flap from the front of your eye during surgery can cause complications, including infection, excess tears and swelling.
