각막절삭술 후 부족 교정된 근시의 방사상 각막 절개술을 이용한 교정효과

Abstract

The authors report clinical results of 6 myopic patients(6 eyes) who showed undercorrection following keratomileusis-in-situ and then underwent radial ker-atotomy to correct the residual myopia. The mean age of patients as 39.2 years, and the mean interval between ker-atomileusis and radial keratotomy was 19.8 months. The mean refractive error was changed from -7.0D preoperatively to -3.23D after radial keratotomy. The average difference of refractive error between treated eye and untreated fellow eye was changed from 5.12D to 1.63D after radial keratotomy. The mean visual acuity was changed from 0.15 preoperatively to 0.33 after radial keratotomy. In conclusion, radial Keratotomy is an useful procedure for correcting under-corrected myopia after Keratomileusis in situ
