This paper describes an excimer laser and its beam delivery system for corneal radial keratotomy.

In general, for correcting nearsightedness over 3 diopters, both LASIK and PRK are better than radial keratotomy (RK).

Radial keratotomy without T-cutting was performed on 245 eyes of 124 patients with 6-8 months of post-operative follow-up.
