高度近视儿童配戴硬性透气性角膜接触镜临床观察

目的探讨6岁以下高度近视儿童配戴硬性透气性角膜接触镜(rigid gas permeable contact lens,RGPCL)2a的临床应用效果。方法在角膜地形图指导下对16例(32眼)3～6岁高度近视儿童进行RGPCL配戴,观察患儿的RGPCL配戴和适应情况,比较最佳框架眼镜和RGPCL矫正视力。随访2a观察并发症的发生情况、屈光度发展及视力提高情况。结果配戴框架眼镜矫正视力与RGPCL比较差异有统计学意义(t=-4.558,P<0.05);配戴RGPCL2a前后矫正视力差异有统计学意义(t=6.027,P<0.05),2a后屈光度增长(-0.17±0.42)D、眼轴长度增长(0.07±0.02)mm。所有患儿均1次配戴成功,配戴试戴镜5min后患儿能正常视物、玩耍,1周内均能适应全天日戴。随访期间,1例患儿因家长没有时间为孩子配戴而弃戴,其余均能日戴,镜片需患儿家长清洗、为患儿配戴,5例患儿能独立摘镜片;所有病例均未发现角膜缘新生血管,无角膜擦伤或角膜溃疡等严重并发症。结论近视性屈光参差及高度近视儿童配戴RGPCL矫正屈光不正安全、有效。     

小儿白内障术后无晶状体眼RGP矫正屈光不正临床观察

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,观察小儿所需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.

Abstract：

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.S 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 (r =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.
