A Cure for Near Sightedness - Radial Keratotomy

Radial keratotomy (RK) is a refractive surgery to correct myopia, or nearsightedness. Radial keratotomy was created by accident and not by meticulous research. The process was discovered by Dr. Svyatoslav Fyodorov, has made one of his patients who had met with a bike accident. The guy with the glasses, which broke on impact, and place the pieces of glass in the eye. The doctor had a plurality of radial incisions in corneal tissue to do, to extract the glass. If the cornea is healed, the doctor discovered that the sight of the boy has been greatly improved.

Manufactured in radial keratotomy (RK), a series of micro-lamellae in the external part of the cornea with the aid of a high-precision calibrated diamond blade. The surgeon administers a local anesthetic because the incisions are shallow and the process is fairly painless. The thickness of the cornea of ​​the eye of the patient measured before surgery. Before the incisions are made, the deep cut diamond cutting tool is located just under the operating microscope. Thus, flattening the curvature of the cornea in such a way, RK easily correct myopia or nearsightedness.

Radial keratotomy was introduced in the United States in 1980. Initially, it was much more than an experimental procedure, the doctors who work with only one eye at a time and wait at least 3 months in order to see the results before you. But the other eye surgeons gathered over time and now could work well both eyes simultaneously. Now is a slight radial keratotomy surgery, which takes about 15 to 20 minutes for each eye.

Radial keratotomy is in continuous improvement, both because of the rapid advances in technology, and the fact that a number of such methods have been successfully carried out. However, RK is not as precise as LASIK and PRK. Since RK is less predictable, a few surgeons now perform this procedure.
