Refractive Surgery

LASIK or Lasik (Laser-Assisted in situ Keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hypermetropia, and astigmatism. The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses.

LASIK is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK, similar to LASEK), and both represent advances over radial keratotomy in the surgical treatment of refractive errors of vision.
