LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is a type of refractive surgery that combines elements of LASIK and PRK to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Unlike LASIK, which involves creating a corneal flap, LASEK involves lifting the corneal epithelium (the outer layer of the cornea) and applying a laser to reshape the cornea.

LASEK surgery is often recommended for patients with thinner corneas or those at higher risk of complications from LASIK. The recovery time is typically longer than LASIK, but LASEK offers similar outcomes in improving vision.

LASEK provides a safe, effective option for patients who require refractive surgery but are not candidates for traditional LASIK.
