摘　　要：对３８例（５９只眼）接受二次放射状角膜切开术，二次切口沿旧切痕完成，随访时间平均１３个月。术前平均等效球镜屈光为－３．７８Ｄ，角膜屈光度为４０．１５Ｄ。术后平均下降等效球镜为２．３０Ｄ，下降角膜屈光２．０４Ｄ，平均提高裸眼视力５行（国际标准视力表）。二次手术疗效与原屈光度及二次术前角膜屈光度无关。二次手术可降低散光度，并发症少。cases 59 eyes received repeated radial keratotomy in which the secondary incisionswere performed along the scars of old incisions.The average follow-up after the reoperation was 13months. Before reoperation,the mean spherical equivalent of the refraction was-3.78D and the meankeratometry was 40.15D.13 months after the reoperation,the mean spherical equivalent of the refrac-tion decreased by 2.30D,and the mean keratometry decreased by 2.04D.After the reoperation,themean uncorrected visual acuity increased by 5 lines.There was no relationship between the therapeuticeffect of the reoperation and the degree of initial myopia or pre-reoperative keratometry.The repeatedradial keratotomy can decrease the degree of astigmatism and its complications are few.
