What is LASEK?

LASEK (LAser Sub-Epithelial Karatomileusis) is a relatively new procedure to treat corneal surface. It is like modified PRK with more advantages. It is usually used for eyes whose corneas are too thin or too flat for LASIK. LASEK is a procedure that involves creating an epithelial flap (instead of a stromal flap in LASIK). The cornea is then reshaped using excimer laser to change the corneal curvature. LASEK has faster visual recovery time and less pain and less potential of corneal haze than PRK does.

What is the difference between LASEK and Epi-LASIK ?
Both LASEK and Epi-LASIK involve the creation of corneal epithelial flaps. In LASEK, the epithelial flap is created by using medical solution. In Epi-LASIK, the flap is created by using a special plastic blade.
