Dry Eyes - After LASIK surgery, tear production is temporarily reduced. For the first six months or longer after surgery, your eyes may feel dry. Dry eyes might impair the quality of your eyesight. Your eye doctor may advise you to use eyedrops for dry eyes. If your eyes are really dry, you may need to have special plugs implanted into your tear ducts to prevent your tears from draining away from the surface of your eyes.
Halos and double vision - After surgery, you may have trouble seeing at night, which normally lasts a few days to a few weeks. Increased light sensitivity, glare, halos surrounding bright lights, or double vision are all possible symptoms. Even if you have a good visual result under conventional testing conditions, your eyesight in dim light (such as at dusk or in fog) may be degraded to a larger extent after surgery than before.
Undercorrections - You won't obtain the sharper vision outcomes you want if the laser removes too little tissue from your eye. Within a year, you may require another LASIK treatment to remove additional tissue.
Overcorrections- It's also conceivable that the laser will burn away too much tissue in your eye.
Astigmatism - Uneven tissue loss might result in astigmatism.
Problems with the flaps - Folding back or removing the flap from the front of your eye during surgery might lead to infections and excessive tears. The outermost corneal tissue layer beneath the flap may form improperly throughout the healing process.
Regression- When your vision gradually returns to your original prescription, this is known as regression. This is a less prevalent problem.
Changes in vision or loss of vision - Surgical complications can cause eyesight loss in rare cases. There are chances that some people might not be able to see as clearly as they previously did.
