Laser-Assisted In Situ Keratomileusis

LASIK (Laser-Assisted In Situ Keratomileusis)

This laser procedure involves creating a thin flap on the cornea (with a laser or a microkeratome) and reshaping the underlying corneal tissue with a laser.



PRK (Photorefractive Keratectomy)

This laser procedure is similar to LASIK, but the laser treatment is performed on the surface of the cornea, not under a corneal flap.



LASEK (Laser Epithelial Keratomileusis)

Epi-LASIK

LASEK is a laser procedure that can be considered something between LASIK and PRK. A corneal flap is created in LASEK, but it is significantly thinner than a LASIK flap and consists of only the top layer of corneal cells (called the epithelium). LASEK is also called Epi-LASIK.
