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 .
Astigmatic keratotomy, arcuate keratotomy, or transverse keratotomy [clarification needed] Radial keratotomy; Hexagonal keratotomy [clarification needed] Epikeratophakia is the removal of the corneal epithelium and replacement with a lathe-cut corneal button.

Radial keratotomy (RK), developed by Russian ophthalmologist Svyatoslav Fyodorov in 1974, uses spoke-shaped incisions, always [clarification needed] made with a diamond knife, to alter the shape of the cornea and reduce myopia or astigmatism; this technique is, in medium to high diopters, usually replaced by other refractive methods.
[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.
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 This early surgical option for myopia has been largely superseded by LASIK and other similar procedures.
Pink eye is among the most unwanted and common infections around. The swollen red eyes, dried pus, and sticky discharge is enough to make anyone suffering with the condition want to avoid being ...
As with other forms of refractive surgery, keratoconjunctivitis sicca, colloquially referred to as 'dry eye,' is the most common complication of PRK, and can be permanent. In more advanced cases, recurrent erosions occur during sleeping from adherence of the corneal epithelium to the upper eyelid with rapid eye movement .
