laser-assisted in-situ keratomileusis (LASIK) keratoplasty in which the excimer laser and microkeratome are combined for vision correction; the microkeratome is used to shave a thin slice and create a hinged flap in the cornea, the flap is reflected back, the exposed cornea is reshaped by the laser, and the flap is replaced, without sutures, to heal back into position.

laser-assisted in-situ keratomileusisAbbreviation: LASIK
A surgical treatment for nearsightedness, farsightedness, and other refractive errors of vision. In this procedure, a microtome is used to cut a thin flap on the surface of the cornea and a laser is used to resculpt the deeper tissue and correct refractive errors. Many patients have a marked improvement in their visual acuity as a result of the procedure. Complications can include infections, hazy vision, double vision, visual halos, the need for reoperation, corneal burns requiring corneal transplant, and blindness.
