38 cases 59 eyes received repeated radial keratotomy in which the secondary incisions were performed along the scars of old incisions. The average follow-up after the reoperation was 13 months. Before reoperation, the mean spherical equivalent of the refraction was -3.78D and the mean keratometry was 40.15D. 13 months after the reoperation, the mean spherical equivalent of the refraction decreased by 2.30D, and the mean keratometry decreased by 2.04D. After the reoperation, the mean uncorrected visual acuity increased by 5 lines. There was no relationship between the therapeutic effect of the reoperation and the degree of initial myopia or pre-reoperative keratometry. The repeated radial keratotomy can decrease the degree of astigmatism and its complications are few.
38例59眼接受了重复放射状角膜切开术，其中二次切口沿旧切口瘢痕进行。再次手术后平均随访13个月。再次手术前，平均等效球镜度为-3.78D，平均角膜曲率为40.15D。再次手术后13个月，平均等效球镜度降低了2.30D，平均角膜曲率降低了2.04D。再次手术后，平均裸眼视力提高了5行。再次手术的治疗效果与初始近视度数或术前角膜曲率无关。重复放射状角膜切开术可降低散光度数，且并发症较少。
