Abstract

The authors report clinical results of 6 myopic patients(6 eyes) who showed undercorrection following keratomileusis-in-situ and then underwent radial keratotomy to correct the residual myopia. The mean age of patients was 39.2 years, and the mean interval between keratomileusis 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 undercorrected myopia after keratomileusis in situ.
