| Abstract |
|
We evaluated the effect of laser in situ keratomileusis(LASIK) to correct refractive errors in myopic patients. We performed LASIK using microkera-tome(SCMD, U.S.A.) an excimer laser (Aesculap Meditec, Germany). Five hundred eighty eyes of three hundred ninty-seven patients underwent LASIK from March 1996 to February 1997. Of 580 eyes, 140 eyes(male 49, female 99 eyes) of 90 patients with minimum follow-up of 6 months were included in this study. They aged from 20 to 63 and among them, simultaneous binocular surgeries were carried out in 38 patients(48%). Topical antibiotics and steroid were instilled for 1 week postoperatively. Preoperative refractive errors ranged from -24.00 to -2.13D (mean -9.17D) and postoperative refractive errors at 6 months ranged from -9.25 to +3.13D (mean -1.70D). The amount of corrected refractive errors ranged from 17.50 to 1.75D(mean 9.17D). Uncorrected visual acuity(UCVA) was hand motion to 0.5 preoperatively and 0.04 to 1.0 at 6 months postoperatively. There was no decreased UCVA postoperatively. Myopia over -1D occured in 79 eyes (56.4%). Among them, 20 eyes (14.3%) underwent enhancements. Seventy-eight percent of cases including enhancements showed UCVA of 0.5 or better at 6 months. LASIK is effective refractive surgery with relatively few complications. |
