现代角膜塑形镜控制小学生近视发展的临床研
摘要：目的观察小学生配戴角膜塑形镜控制近视发展的疗效以及对其角膜厚度、角膜曲率等方面的影响。
方法：对69例小学生近视眼患者戴镜后1天、1周、1个月、3个月、半年、1年进行复查。观察裸眼视力、角膜曲率、角膜厚度及配戴前后近视度数变化，进行对比分析。结果：配戴满1年，停戴一周，门诊快速扩瞳验光。屈光度比较：配戴前等效球镜度为-2.85±1.13D，等效球镜度增幅0.17±0.56D；其中有28例小学生等值球镜下降0.25~0.75DS。角膜曲率比较：配戴前平均角膜曲率43.26±1.42D，配戴后平均角膜曲率为43.15±1.41D，较配戴前扁平0.11±0.32D,但两者比较差异无统计学意义，P0.05。角膜中央厚度比较：戴镜后角膜中央厚度减薄0.15-6.89um，差异无统计学意义，P0.05。结论：配戴角膜塑形镜可有效控制小学生近视度数的发展，部分小学生近视度数还有所下降，角膜曲率、膜中央厚度无明显改变。现代角膜塑形镜为治疗小学生近视的较好的方法。
