LASEK Eye Surgery FAQs

If you are considering LASEK eye surgery, you may be confused about what the procedure entails and how it differs from other refractive surgery options. Review the following questions to learn more about the LASEK procedure.

Is there a difference between LASIK and LASEK?

Yes. The procedures are slightly different, but both use lasers to reshape the cornea and correct vision. LASEK is best for people with large pupils or thin corneas and who are not good candidates for LASIK.

Is LASEK surgery safe?

Yes. LASEK is a common procedure that is considered extremely safe. Your eye surgeon will review your vision correction needs and evaluate your candidacy for treatment with LASEK surgery.

How is the procedure performed?

Prior to undergoing LASEK surgery, the eyes will be numbed with eye drops. The surgeon uses a tiny blade to make an ultra-thin flap in the eye's epithelial layer. A special solution is used to loosen the edges of the flap so it can be lifted out of the way, providing access to the underlying corneal tissue. The cornea is then reshaped using an excimer laser and the flap is smoothed back into place.

Are there risks?

As with any surgical procedure, LASEK eye surgery does have some risks. Complications can arise from laser eye surgery, such as infection, corneal flap wrinkles, overcorrection or undercorrection, and other certain complications. However, these are extremely rare, many of them occurring in only 1 percent to 2 percent of patients or fewer. After refractive surgery, some patients may see starbursts, halos, or glares associated with lights, but these symptoms should clear up within a few days or a few weeks. Additionally, some patients may experience dry eyes or eye irritation, which typically resolve within a few days.
