Abstract

Radial Keratotomy (RK) is a surgical procedure designed to correct moderate amounts of myopia. Currently the procedure consists of eight peripheral incisions of up to 90% of the corneal thickness leaving a 3 - 4 mm central clear zone centered on the optic axis. The procedure is designed to weaken the corneal structure inducing an increase in the corneal radius of curvature, thereby reducing corneal dioptric power. After the surgery patients often complain of increased sensitivity to glare; this subjective complaint¹ is measurable² and has resulted in changes in behavior such as altered driving patterns and refusing surgery in the second eye³.
