摘　　要：目的观察小儿白内障术后因无晶状体而配戴RGP的临床应用效果。方法为5例（10只眼）因小儿白内障术后无晶状体的患儿验配RGP，观察d,JL所需RGP的参数，随访观察镜片配戴情况，并发症发生情况，镜片更换及矫正视力。结果所有患者均能正常配戴RGP，所配戴RGP基弧平均7．6，屈光度平均＋24．5D，直径8．6mm。戴镜前后眼球震颤振幅分别为（11．0±4．2）度和（6．5±3．4）度，差异有统计学意义（t=9．0，P〈0．05），振频分别为29．0±9．6和19．6±2．9，有显著统计学意义（t=23．1，P〈0．05）。平均6个月更换一次镜片。随访期间无并发症发生。结论先天性白内障术后无晶状体眼配戴RGP安全有效。Objective To investigate the effect of the rigid gas permeable contact lenses （RGP） for pediatric aphakia. Methods Ten eyes of 5 patients with cataract aphakia who were fitted into RGP for aggressive visual rehabilitation. The RGP lenses parameters such as basic curve （BC）, power, and diameter were evaluated. Complications, correct visual acuity, and the number of lenses during the period of follow-up were observed. Results All patients could wear RGP lenses normally. The average BC of lenses was 7.6, power was ＋24.5 D, and diameter was 8.6. The nystagmus amplitude were 11.0±4.2 degree and 6.5±3.4 degree before and after wearing RGP lenses （t =9.0, P 〈0.05）. The nystagmus frequency were 29.0±9.6 and 19.6±2.9 before and after wearing RGP lenses （t =23.5, P 〈0.05）. The average changing lenses cycle was 6 months. No complications occurred during the follow-up periods. Conclusions The RGP lenses are safe and effective to pediatric aphakia.
