Abstract

We had performed eight incision radial keratotomy employing the American technique on 247 eyes of 166 patients from July, 1986 to December, 1987. The clinical results including postoperative uncorrected visual acuity, refractive power, and keratometric power were followed up at 6 months on 92(37.2%) of 247 cases. The results were as follows; 1. The mean postoperative uncorrected visual acuity was 0.595 and 60.9% of all cases had 20/40 or better uncorrected visual acuity. 2. The mean reduction in postoperative refractive power was 3.26 diopters. 3. The mean reduction in postoperative keratometric power was 3.08 diopters. 4. Operative and postoperative complications were visual fluctuation(142 eyes), photophobia(52 eyes), microperforation(7 eyes), transient increase of IOP(5 eyes), changes of peripheral cornea(6 eyes), and one case of postoperative cataract with persistent hypotony and uveitis.
