Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov , a Russian ophthalmologist . It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy , LASIK , Epi-LASIK and the phakic intraocular lens .
Radial keratotomy is a refractive surgery procedure where the surgeon makes a spoke-like pattern of incisions into the cornea to modify its shape. This early surgical option for myopia has been largely superseded by LASIK and other similar procedures.
In 1974 a refractive procedure called Radial Keratotomy (RK) was developed in the USSR by Svyatoslav Fyodorov and later introduced to the United States. RK involves making a number of cuts in the cornea to change its shape and correct refractive errors. The incisions are made with a diamond knife. Following the introduction of RK, doctors ...
In the 1970s he developed the surgical technique he is most famous for, the radial keratotomy, to change the shape of the cornea and cure myopia. [2] In 1986, Fyodorov designed the first posterior chamber phakic IOL in the "collar-button" or "mushroom" configuration and manufactured the pIOL from silicone. In 1980 he became the head of the ...
[29] [30] Five years later, in 1985, Steven Trokel at the Edward S. Harkness Eye Institute, Columbia University in New York City, published his work using the excimer laser in radial keratotomy. He wrote, "The central corneal flattening obtained by radial diamond knife incisions has been duplicated by radial laser incisions in 18 enucleated ...

Tsutomu Sato (1902 – June 9, 1960) was a Japanese ophthalmologist who performed an early version of the radial keratotomy and was the first professor at the Research Institute of Ophthalmology at Juntendo University School of Medicine.
