The safety, efficacy, and stability of second-attempt radial keratotomy were evaluated in 20 eyes of 12 patients from September 1, 1982, to August 31, 1983. The average amount of refractive error change was 1.89 diopters with 1.38 diopters of corneal curvature flattening. The effect of the second-attempt operation was about 60% that of the first-attempt operation. No significant surgical complications were observed in this study.
1982年9月1日至1983年8月31日期间，对12例患者的20只眼睛进行了二次放射状角膜切开术的安全性、有效性和稳定性评估。屈光不正变化的平均量为1.89屈光度，角膜曲率变平1.38屈光度。二次手术的效果约为首次手术的60%。本研究未观察到明显的手术并发症。
