Radial Keratotomy (RK) is a type of eye surgery that is used to correct nearsightedness (myopia).During RK, a surgeon uses a special blade to make several small, curved incisions in the cornea (the clear outer layer of the eye).
The incisions cause the cornea to flatten, which helps to refocus light so that it lands directly on the retina.RK is a permanent procedure and the patient will not need to have it repeated.
The surgery generally takes about 20 minutes per eye and the patient may experience vision improvement within the first two weeks after the procedure.While RK is generally successful, there are some potential risks and complications that include infection, swelling, and even vision loss.
It is important to discuss the risks and benefits of the procedure with your doctor before having RK performed.
