| refractive keratotomy | Modification of corneal curvature by means of corneal incisions to minimise hyperopia, myopia, or astigmatism.In this type of radial keratotomy surgery, performed by excimer laser, pie-shaped pieces of cornea are removed under local anaesthetic. The resulting scar tissue formation reshapes the cornea. This class of surgery is somewhat unpredictable, and its long-term effects are still unknown. (05 Mar 2000) |
| keratotomy | A surgical incision (cut) of the cornea. A radial keratotomy is a surgical procedure designed to flatten the cornea and thereby correct myopia (nearsightedness). It is called a radial keratotomy because the incisions resemble the spokes in a bicycle wheel. (12 Dec 1998) |
| keratotomy, radial | A procedure to treat myopia by cutting radial slits into the cornea to flatten it and thereby change its refractive properties. (12 Dec 1998) |
