Abstract

Laser in situ keratomileusis (LASIK) is a procedure involving creation of a corneal flap followed by reshaping of the stromal bed with the 193 nm argon fluoride excimer laser. It is currently the most commonly performed procedure for the correction of refractive errors like myopia, astigmatism and hyperopia. Rapid visual recovery, minimal postoperative discomfort and reduced subepithelial haze are important advantages that LASIK has over surface photorefractive keratectomy (PRK). Complications following LASIK can be divided into intraoperative complications, early postoperative complications, presenting within first few days after the procedure and late postoperative complications presenting weeks to months after the surgery.
