角膜矫形学治疗轻中度近视的临床观察

Clinical observation on orthokeratology for correcting myopia

目的 :评价角膜矫形学治疗 -6 0D以下近视的有效性及安全性。方法 :对接受角膜形学治疗的 1 0 2例 2 0 2只眼追踪至 6个月的情况进行分析。结果 :治疗后六个月裸眼视力≥1 0者占 75 3 % ,剩余屈光度≤ -0 5D者占 76 7% ,治疗后的裸眼视力 ,剩余屈光度及角膜曲率与治疗前比较 ,差异均有显著性意义 (P <0 0 1 )。结论 :角膜矫形学治疗 -6 0D以下近视安全有效 ,而且稳定性好。

Objective:To evaluate the efficacy and safety of orthokeratology of correction of myopia lower than -6.0D.Methods:A total of 202 eyes in 102 patients received the process of orthokeratology and followed up for six months were analysed retrospectively.Results:Six months after treatment,75.3% of the eyes achieved an uncorrected visual acuity of 20/20 or better,76.7% of the eyes had a refraction≤-0.5D.The mean of uncorrected visual acuity,residual refraction and curvature of the central cornea were different satistically before and after treatment( P <0.01).Conclusion:Orthokeratology is a safe,effective and stable procedure for correcting myopia lower than -6.0D.
