Answer» What is Radial Keratotomy mean? Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness) that was developed in 1974, by Svyatoslav Fyodorov, a Russian ophthalmologist. It has been largely supplanted by newer operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic intraocular lens. Approximately 10% of all practicing ophthalmologists in the United States have performed several hundred thousand RK procedures. reference
