After surgery

Immediately after surgery, your eye may burn or itch and be watery. You'll probably have blurred vision. You may be given pain medication or eyedrops to keep you comfortable for several hours after the procedure. Your eye doctor might also ask you to wear a shield over your eye at night until your eye heals.

Typically you're able to see the day of your surgery, but your vision won't necessarily be better right away. Expect your vision to improve over the next two to three months. Most people who have refractive surgery eventually attain 20/25 or better vision. Your chances for improved vision are based, in part, on how good your vision was before surgery.

Other types of refractive surgery
Your eye doctor may recommend another type of refractive surgery if you're not a good candidate for LASIK eye surgery. These include:

*

Photorefractive keratectomy (PRK). PRK is sometimes used if you have a low to moderate degree of nearsightedness or farsightedness, or if you have nearsightedness with astigmatism. PRK removes the thin surface layer of your cornea (epithelium). Your eye surgeon then uses a laser to flatten your cornea or make its curve steeper.

The exposed surface of your cornea repairs itself, assisted by a contact lens you wear as a bandage over your eye for three or four days after surgery. You might have eye pain for a few days until your cornea heals. It generally takes up to a week for your eye to regenerate the surface tissue that was removed. During this time you'll notice variations in your vision. It may take three to six months before your vision improves completely. Most people undergoing PRK have both eyes done on the same day.

PRK has become less common in recent years because more eye surgeons prefer the LASIK procedure. Healing after LASIK is more predictable and usually involves less discomfort and scarring.
*

Laser epithelial keratomileusis (LASEK). LASEK is similar to LASIK eye surgery and might be an option if you aren't eligible for LASIK. During a LASEK procedure, a much thinner layer — the surface layer (epithelium) — of your cornea is folded back to allow the laser to focus on parts of your cornea that need reshaping. The epithelial flap is then replaced.

If you have very thin corneas, you might be a better candidate for LASEK because the procedure allows your doctor to remove less of your cornea. People who play sports or have jobs that carry a high risk of eye injuries might also prefer LASEK because a thinner flap means less damage to your vision should the flap be torn before it can heal. As with LASIK, the LASEK procedure can be done on both eyes on the same day.
