![]() It's also possible that the laser will remove too much tissue from your eye. You may need another LASIK procedure within a year to remove more tissue. Undercorrections are more common for people who are nearsighted. Undercorrections.If the laser removes too little tissue from your eye, you won't get the clearer vision results you were hoping for.You might notice increased light sensitivity, glare, halos around bright lights or double vision.Įven when a good visual result is measured under standard testing conditions, your vision in dim light (such as at dusk or in fog) may be reduced to a greater degree after the surgery than before the surgery. ![]() You may have difficulty seeing at night after surgery, which usually lasts a few days to a few weeks. If you experience severe dry eyes, you could opt for another procedure to get special plugs put in your tear ducts to prevent your tears from draining away from the surface of your eyes. Your eye doctor might recommend eyedrops for dry eyes. Dry eyes can reduce the quality of your vision. For the first six months or so after your surgery, your eyes may feel unusually dry as they heal. LASIK surgery causes a temporary decrease in tear production. These usually clear up after a few weeks or months, and very few people consider them to be a long-term problem.ĭry eyes. But certain side effects of LASIK eye surgery, particularly dry eyes and temporary visual problems such as glare, are fairly common. Your eye doctor will talk with you about whether LASIK surgery or another similar refractive procedure is an option that will work for you.Ĭomplications that result in a loss of vision are very rare. If you're considering LASIK surgery, you probably already wear glasses or contact lenses. When the cornea curves or flattens unevenly, the result is astigmatism, which disrupts focus of near and distant vision. This makes near vision, and sometimes distant vision, blurry. When you have a shorter than average eyeball or a cornea that is too flat, light focuses behind the retina instead of on it. You can see objects that are close fairly clearly, but not those that are far away. When your eyeball is slightly longer than normal or when the cornea curves too sharply, light rays focus in front of the retina and blur distant vision. LASIK surgery may be an option for the correction of one of these vision problems: This makes close-up objects appear blurry. ![]() In farsightedness (hyperopia), your cornea doesn't refract light properly, so the point of focus falls behind the retina. With normal vision, an image is sharply focused onto the surface of the retina.
