(rē-frak'tiv ker'ă-tot'ŏ-mē) Modification of corneal curvature by means of corneal incisions to minimize hyperopia, myopia, or astigmatism. In this type of radial keratotomy surgery, performed by excimer laser, wedge-shaped pieces of cornea are removed under local anesthetic. The resulting scar tissue formation reshapes the cornea.
