LASEK (Laser-Assisted Sub-Epithelial Keratectomy)

« View Glossary

A hybrid of photorefractive keratectomy (PRK) and laser-assisted in-situ keratomileusis (LASIK), the goal of LASEK is the preservation of the corneal epithelium. Rather than creating a flap with a laser (as in LASIK) or scraping and removing the patient’s epithelium (as in PRK), LASEK treats the epithelium with alcohol to loosen and separate it from the stroma, and it is then rolled back to perform the refractive surgery.
