Before the development of the excimer laser, incisional techniques were the mainstay of keratorefractive surgery.
Introduction of 193nm argon-fluoride excimer laser into clinical practice in the late 1980s rapidly changed keratorefractive surgery by enabling highly controlled removal of corneal tissue and so modification of corneal curvature.
In the case of excimer laser keratorefractive surgery, all of the longest follow up studies of myopic and hyperopic PRK demonstrate refractive stability.
In keratorefractive surgery, corneal shape is changed either indirectly by weakening the cornea or directly by selective tissue ablation.
