In recent years, radial keratotomy has emerged as a controversial procedure for the correction of myopia. Although this method seems to be relatively effective for hypermetropization, postoperative problems have been reported. In Japan, Dr. Tsutomo Sato developed this procedure and applied it both to patients with keratoconus and with myopia. Between 1951 and 1959, surgery was performed on 681 eyes. Although the exact incidence of postoperative bullous keratopathy among these patients is not known, 69 eyes with severe bullous keratopathy have been followed-up at our clinic. We conclude that radial keratotomy should be performed only after consideration of all of the consequences.
