What is Epi-LASIK?
Epi-LASIK and Surface LASIK are different terms for the same procedure.  The term “Epi” is the medical term for “surface.”  I prefer to use the term “surface” because it is more clearly understood.

What is the difference between Surface LASIK and regular LASIK?
The difference is what layer of the cornea the laser is applied to.  With Surface LASIK the laser is applied to the surface of the permanent layers of the cornea.  With regular LASIK the laser is applied to the deeper permanent layers of the cornea. They have the same WaveScan/CustomVue pre-op measuring technique.  Both procedures have the same precision in the application of the laser treatment with Iris Registration and 3-D active eye tracking.

What types of patients usually have Surface LASIK?
Some eye conditions require us to do Surface LASIK.  For example, thin corneas, dry eyes, and strong prescriptions.  Patients who want to maximize the safety and avoid any additional risks of LASIK are good candidates for Surface LASIK.  It also requires a patient being willing to wait for a few days while their eyes heal to return to normal activities.

Is Surface LASIK painful?
No, the procedure is painless.  For the first few days the eyes feel scratchy. Usually, no pain medicines are needed.

1.  Some eye conditions require you having Surface LASIK.  2. You want to maximize the safety while having your vision corrected.  3.  Minimize any long-term complications.  4.  You are willing to have a few blurry vision days at first while your eye heals.
