ABSTRACT:
A method of ocular refractive surgery which employs heat application to reshape and enhance the refractive power of the central cornea of a surgical subject. Radio frequency energy is employed to coagulate segments of corneal stroma in the perilimbal area at the pole of the corneal meridian having the lowest keratometric reading, causing the radius of curvature of the central cornea to increase in that meridian, whereby astigmatism can be safely and permanently corrected.
