It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the Intraocular lens#Intraocular lenses for correcting refractive errors, phakic intraocular lens.

The original technique – consisting of incisions from periphery to center – was called the "Russian technique", while the later advances of performing controlled incision from center to periphery was called the "American technique".Gulani AC, Fyodorov S: Future Directions in Vision course, June 1997 RK may be performed with different types, numbers, and patterns of ...
