LASEK Surgery or laser epithelial keratomileusis is an alternative to LASIK surgery and a cousin of PRK. LASEK combines elements of both surgeries and can be used for patients with astigmatism, nearsightedness and farsightedness.

Candidates for LASEK

Because the procedure is for people with thinner corneas, the main difference in candidacy is thin corneas. This procedure can be applied for all the same people using LASIK surgery.

For LASIK candidacy, see LASIK Candidacy


There are no discernible differences between LASEK and LASIK for pre-op. If you wear contacts you should remove them days or weeks (depending on the contact lens) prior to the procedure. You should remove all makeup a few days earlier, too. And make sure to secure a driver to take you to and from the procedure.

LASEK Surgery – The procedure

During LASEK surgery, a trephine, a finer blade and a 20-percent alcohol solution are used to create the flap. This helps to prevent many of the potential complications that come along with cutting and possibly reattaching the flap.
The exposed tissue is treated using an excimer laser to sculpt the cornea.

LASEK Surgery – Post-Op

Two things to expect in post-op that are different than LASIK surgery: Moderate discomfort and the addition of a protective contact lens to your eyewear collection for up to a week. This may affect driving immediately after surgery.

As far as final results, patients of LASIK and LASEK can expect similar results, though preliminary studies give a slight edge to LASEK surgery when it comes down to measuring the vision of like patients.
