What are the risks and possible complications of LASIK?

LASIK is generally considered to be safe, but as in all surgical procedures there are some risks and possible complications to consider. The incidence of most problems is low.

If the microkeratome creates a free cap instead of a flap it is simply laid back in place after the cornea is treated with the laser. If an imperfect flap occurs, the laser portion of the treatment will be abandoned. After the flap is put back in place to heal, surgery can be tried again after a few months.

Striaetions or wrinkles in the flap can cause astigmatism. The most likely causes are rubbing your eyes before they are fully healed or the flap not being properly lined back up after your surgery. If of great inconvenience, a second procedure can be done to relift and smooth out the flap.

Most patients experience some temporary dryness after LASIK, but in some people the condition is lasting. Eye drops can help provide relief.

Glare and halos are probably the most common side effect of LASIK. In fact, many patients experience some level of glare and halos at first, but over time they resolve themselves (generally in a few weeks to a few months). Most of those who do have lasting effects say they are not debilitating.
