Radial keratotomy surgery was begun in a private ophthalmologic practice in July 1980. A statistical analysis of the first 557 cases is presented. The mean postoperative refractive error was -4.00 diopters. One year after surgery, 95% of the patients with a preoperative refractive error of -3.00 diopters or less had a visual acuity of 20/40 or better, and 79% of those with a refractive error of -3.25 to -6.00 diopters had a visual acuity of 20/40 or better. The mean decrease in keratotomy readings at six months postoperatively was 2.95 diopters. Of the patients with a preoperative refractive error of less than 6 diopters, 85% wore glasses rarely or not at all, whereas 15% wore a refractive correction full time.
放射状角膜切开术于1980年7月在一家私人眼科诊所开展。本文对首批557例病例进行了统计分析。术后平均屈光不正为-4.00屈光度。术后一年，术前屈光不正为-3.00屈光度或更低的患者中，95%的视力达到20/40或更好；术前屈光不正为-3.25至-6.00屈光度的患者中，79%的视力达到20/40或更好。术后六个月角膜切开术读数的平均下降值为2.95屈光度。术前屈光不正小于6屈光度的患者中，85%很少或根本不戴眼镜，而15%的患者则一直佩戴屈光矫正眼镜。
