青少年配戴角膜塑形镜与框架眼镜后屈光状态的对照分析

Comparisons of the refractive status after orthokeratology wearing or glasses wearing in myopic adolescents

目的观察配戴角膜塑形镜治疗青少年近视的临床疗效。方法连续选取我院2011年9月至2012年12月轻中度青少年近视患者共78例(156只眼)随机分为两组,框架眼镜组(A组)、角膜塑形镜组(B组),比较两组矫正后视力、屈光度、角膜曲率等情况。结果戴镜1年后,B组裸眼视力明显优于A组原框架眼镜矫正视力;B组患者的屈光度明显低于A组的屈光度(P<0.05);A组患者戴镜后角膜曲率较戴镜前增高,B组患者戴镜后角膜曲率较戴镜前下降,两组比较差异有统计学意义(P<0.05)。结论角膜塑形镜矫治青少年近视疗效确切,能有效的改善患者的视功能,控制近视的发展,值得推广应用。

Objective To investigate the role of orthokeratology in the treatment of adolescent myopia. Methods A total of 78 adolescent myopia patients（ 156 eyes） were continuously enrolled from 2011 September to 2012 December and were randomly prescribed with either glasses（ group A） or orthokeratology（ group B）. Visual acuity,refraction,and corneal curvature were compared between the two groups. Results After 1 year,visual acuity was better in patients treated with orthokeratology than in patients wearing glasses. Refractive error was also significantly smaller in patients wearing orthokeratology（ P〈 0. 05）. Corneal curvature decreased in patients wearing orthokeratology,whereas it increased in patients wearing glasses,and there was a significant difference between the two groups（ P〈 0. 05）. Conclusion Orthokeratology is an effective treatment for juvenile myopia. It improves the visual function and delays the development of myopia in adolescents.
