The surgeon uses a delicate diamond-tipped blade, a microscope, and microscopic instruments to make several spoke-like, "radial" incisions in the nonviewing (peripheral) portion of the cornea.
Myopia
A radial keratotomy is performed to treat nearsightedness (myopia). It involves making incisions in the cornea to flatten its steep curvature and improve vision.
Radial Keratotomy or RK is used to treat nearsightedness also known as myopia. This procedure was developed by Svyatoslav Fyodorov a Russian optamologist in 1974.
Radial keratotomy (RK) is a type of eye surgery used to correct myopia (nearsightedness).
myopia
Radial keratotomy is a surgical procedure used to correct nearsightedness (myopia). It is best suited for individuals with low to moderate levels of myopia who are not good candidates for other vision correction procedures like LASIK or PRK. It is important to consult with an ophthalmologist to determine if you are a suitable candidate for radial keratotomy.
photorefractive Keratectomy
Radial keratotomy is one of several surgical techniques to correct nearsightedness, reducing or eliminating the need for corrective lenses.

Correcting nearsightedness
Normal anatomyThe cornea is the clear covering over the colored iris and pupil of the eye. The cornea and lens of the eye help focus light on the retina so that the eye can see.IndicationsRadial keratotomy is used to correct nearsightedness, also called myopia. Myopia occurs when the cornea and lens focus light in front of, rather than on, the retina. Correction of myopia with radial keratotomy eliminates the need for corrective lenses (glasses or contact lenses).ProcedureWhile you are awake and pain-free (using local anesthesia), a series of delicate incisions are made around the cornea. This flattens the center of the cornea in order to change the focus of light rays on the retina. Each eye is operated on separately, and on different days.AftercareAn eye patch or dark glasses are worn for several days. The final outcome of your corrected vision can take up to several months.Advances in refractive surgery are being made rapidly. New procedures that are slowly replacing radial keratotomy are being used more frequently. Use of the Excimer laser has greatly improved refractive surgery. Consultation with a specialist is advised before deciding on a particular procedure.Reviewed ByReview Date: 02/17/2009Paul B.
