Refractive Surgery

Refractive surgery - Overview

LASIK uses a laser (a strong beam of light) to change the shape of the cornea and help make vision clearer. It works best for adults with nearsightedness, farsightedness, or astigmatism. It can’t fix presbyopia. For LASIK to work correctly, your vision needs to be stable (meaning your eyeglass or contact lens prescription stays the same over time).

Risks and complications

LASIK can cause side effects, just like any surgery. Common side effects include:

  • Dry eye
  • Seeing a glare or halo around bright lights
  • Double vision
  • Blurry vision
  • Sensitivity to light

These side effects usually go away after a few months. Your eye doctor may give you eye drops or other medicines to help with these side effects. Rarely, these problems can be permanent.

Other risks of LASIK include:
  • Infection
  • Problems with corneal healing
  • Vision loss, or seeing less clearly than you did before surgery

If LASIK causes vision loss, you may need another surgery to fix it. Rarely, vision loss from LASIK may be permanent.

If you see clearly with eyeglasses or contacts, you may decide that the risks of LASIK outweigh the benefits. Talk with your eye doctor about the risks and benefits and decide together if surgery is right for you.


During an eye exam before the surgery, your eye doctor will use a scanner to make a detailed image of your cornea. This image will guide the laser during surgery.

Just before surgery, your doctor will put drops in your eye to make it numb. They may also give you a medicine to help you relax.

During the surgery, your doctor will cut a small flap in your cornea and fold it back. Then they’ll shine a laser into your eye. The laser will be programmed to change your cornea into the correct shape. Then they’ll put the corneal flap back in place.
