We report an easy, safe technique to treat regression and haze after excimer laser photorefractive keratectomy (PRK), in which the hyperplastic epithelium is removed manually. The results of scraping of epithelium in 21 eyes of 20 patients are presented. Mean follow-up time was 3 months (range 1 to 7). The mean spherical equivalent refraction before photorefractive keratectomy was -9.93 +/- 2.95 diopters (D); the mean spherical equivalent refraction before epithelial scraping was -3.82 +/- 2.87 D; after scraping it declined to -2.63 +/- 4.04 D. The uncorrected visual acuity after scraping was 20/50 or better in 6 eyes. In 5 others it was between 20/60 and 20/100, and in 10 eyes it was worse than 20/100. The corrected visual acuity after scraping was 20/30 or better in 8 eyes, between 20/40 and 20/60 in 8 eyes, and between 20/60 and 20/100 in 5 eyes.
我们报告了一种简单、安全的技术，用于治疗准分子激光屈光性角膜切削术（PRK）后的回退和角膜混浊，即手动去除增生的上皮。本文介绍了对20例患者的21只眼进行上皮刮除的结果。平均随访时间为3个月（范围1至7个月）。屈光性角膜切削术前平均等效球镜度为-9.93±2.95屈光度（D）；上皮刮除术前平均等效球镜度为-3.82±2.87D；刮除后降至-2.63±4.04D。刮除术后裸眼视力20/50或更好的有6只眼。另外5只眼在20/60至20/100之间，10只眼低于20/100。刮除术后矫正视力20/30或更好的有8只眼，8只眼在20/40至20/60之间，5只眼在20/60至20/100之间。
