Surgical procedure that corrects myopia; shallow incisions are made in the cornea, causing it to bulge.
A surgical procedure to correct nearsightedness by making small incisions in the clear outer covering (cornea) of the eye in a spokelike (radial) pattern. The incisions penetrate almost all the way through the cornea, which flattens in the center and becomes steeper in its outer, downward- sloping portion. This change shifts the way light rays are bent as they pass through the cornea, allowing them to focus on the retina and correcting the nearsightedness.
Surgical therapy for nearsightedness. Very shallow, bloodless, hairline, radial incisions are made (e.g., by a laser) in the outer portion of the cornea where they will not interfere with vision. This allows the cornea to flatten and helps correct the nearsightedness. About two thirds of patients undergoing this procedure will be able to eliminate the use of glasses or contact lenses.
A surgical intervention that employs a blade equipped with a diamond tip is employed to create multiple radial incisions in the outer edge of the cornea, which is the nonviewing region. This procedure aims to enhance the visual focus of the eye and rectify myopia by inducing a flattening effect on the cornea.
A less frequent technique involves creating radiating incisions within the cornea (the clear front section of the eyeball), extending up to but not through its innermost layer, with the goal of mitigating myopia (shortsightedness). Radial keratotomy has been largely supplanted by laser procedures, like LASIK, which present a lower likelihood of causing lasting harm to the eye.
