Laser refractive surgery: a review and current status

The aim of corneal refractive surgery is to modify the anterior surface of the cornea for the correction of myopia, hyperopia, and astigmatism. The air-tear film interface is a powerful refractive surface. Small changes in the curvature can induce large shifts in refractive power. The exquisite nature of laser-tissue interaction with corneal tissue allows successful application of lasers for refractive surgery. Numerous systems have been developed for clinical applications. An overview is provided of the current clinical and research status of laser refractive surgery.
