Seventeen human myopic eyes underwent eximer laser (Excimed UV 200 LA, Excimer Laser Summit Technology) refractive Keratectomy for correction of myopia. All eyes were followed up over three months. During the follow-up period, recovery of corneal epithelium. change of vision, change of refractory error, change of central corneal thickness, and subepithelial opacity were examined. The results and conclusion were as follows; 1. Corneal epithelial defects were recovered within three days. 2. Preoperative mean vision was 5/50 and postoperative mean vision was 40/50. 3. Preoperative refractive errors ranged from -1.25D to -7.25D and the mean refractive error was -4.25D. After three months, the refractory error was from -0.75D to +2.25D with a mean refraction of +0.49D. 4. Mean central corneal thickness was 558.8 micrometer at 90th day of postoperative period, and 493.4 micrometer ant 7th day of postoperative period and increased to 511.8 micrometer at 90th day of postoperative period. 5. Although all the eyes revealed corneal subepithelial opacities in slit-lamp examination the opacities disappeared or remained to insignificant degree at 90th day of postoperative period. 6. Above results showed the Excimer Laser refractiver Keratectomy a exact and safe method for correction of myopia.
