What is LASIK Eye Surgery?

LASIK is considered by most refractive surgeons to be the gold standard of laser eye corrective surgery. What does LASIK involve? It involves reshaping the cornea, like all other laser eye surgeries, but specifically, by creating a small flap in the front of the cornea. The cornea is the clear part of the front of the eye.

We create a 100-micron flap, lift the flap up and apply an excimer laser – similar to the same laser that’s used for PRK, to reshape the surface of the eye. Put the flap back down, and let the eye heal over a very short period of time, giving patients a very fast recovery after having had laser eye surgery with minimal discomfort.

Candidates for LASIK could include anybody between a minus 10 to a plus 3 in terms of refraction or high myope or even a low hypero. The most important thing that your surgeon will look for when assessing your candidacy for laser eye surgery is to make sure that your cornea, which is the clear part of the eye, is thick enough to allow removal of some of the tissue.

Patients with severe dry eye, patients with autoimmune diseases, are not candidates for LASIK, and unfortunately will have to look at other opportunities to remove their glasses.

The side effects associated with LASIK include dry eyes, glare and halos at night. The other thing that LASIK patients need to be aware of, especially in the short term immediately after surgery, is they shouldn’t rub their eyes, because if they do, that flap can get dislodged and be moved and need to be repositioned.

Long term, for people particularly who are actively involved in contact sports or otherwise, if they get hit in the eye – even 10 or 15 years after having had surgery, they can move that flap. So if you’re into contact sports like boxing, or MMA, or other similar sports, LASIK may not be the right procedure for you.

But for 99 percent of patients LASIK is a great procedure with amazing and phenomenal outcomes. To find out if you’re a candidate for LASIK, please talk to your optometrist or your local refractive surgeon, who will be more than happy to evaluate you and share their thoughts. Now health
