目的 观察隔天夜间配戴角膜塑形镜、连续夜间配戴角膜塑形镜及框架眼镜控制青少年低度近视的临床效果.方法 收集成都医学院第一附属医院眼科门诊2014年4月至2015年6月诊治的7~16岁低度近视患者123例(246眼),随机将患者分为隔天夜间配戴角膜塑形镜组38例(76眼),连续夜间佩戴角膜塑形镜组40例(80眼),配戴框架眼镜组45例(90眼),观察戴镜前和戴镜后1周、1、3、6月和1年的裸眼视力和角膜曲率,观察1年后3组患者的屈光度及眼轴变化.结果 与戴镜前比较,戴镜1周、1、3、6月和1年的裸眼视力均明显提高,角膜曲率明显下降,差异有统计学意义(P<0.05),1年后,两组角膜塑形镜的屈光度及眼轴长均小于框架眼镜组,差异有统计学意义(P<0.05);两组角膜塑形镜之间屈光度数和眼轴长比较,差异无统计学意义(P>0.05).结论 隔天配戴角膜塑形镜治疗低度近视效果明显,可提高裸眼视力,延缓屈光度增加,减少戴镜依赖性.%Objective To observe the respective clinical effect of wearing orthokeratology (OK)lenses overnight every other day and continuously and that of wearing frame glasses on the adolescent low myopia.Methods 123 low myopia patients (246 eyes)with the age of 7 to 16,who were treated in The First Affiliated Hospital of Chengdu Medical College from April of 2014 to June of 2015,were selected as the research objects and divided randomly into the group of wearing OK lenses overnight every other day (38 cases with 76 eyes),the group of wearing OK lenses continuously (40 cases with 80 eyes),and the group of wearing frame glasses (45 cases with 90 eyes).The uncorrected visual acuity and corneal curvature were examined after 1 week,1 month,3 and 6 months, and 1 year respectively,and the diopter and axial length were checked after 1 year.Results Compared with before wearing glasses,the uncorrected visual acuity was improved significantly and the corneal curvature was decreased significantly after 1 week,1 month,3 and 6 months,and 1 year respectively in the two groups of wearing OK lenses (P<0.05).The diopter and axial length in the two groups of wearing OK lenses were significantly less than those in the group of wearing frame glasses (P<0.05);There were no significant differences between the two groups of wearing OK lenses (P>0.05).Conclusion The treatment of wearing OK lenses every other day is effective in alleviating the myopic development,improving the uncorrected visual acuity,delaying the increase of diopter,and reducing the dependence of wearing glasses for adolescents with low myopia.
