大直径设计角膜塑形镜治疗青少年儿童中低度近视的短期效果

Short-term Efficacy of Large Diameter Design Orthokeratology Lens in the Treatment of Moderate and Low Myopia in Adolescents and Children

目的:观察大直径设计角膜塑形镜治疗青少年儿童中低度近视的短期疗效。方法:选取2016年11月-2018年11月在本院就诊的中低度近视青少年儿童120例。随机分为试验组和对照组,各60例。试验组配戴大直径设计角膜塑形镜,对照组配戴框架眼镜。观察两组治疗效果。结果:治疗1年后,试验组裸眼视力(UCVA)较治疗前提升,屈光度下降(P<0.05);对照组UCVA较治疗前下降,屈光度增加(P<0.05);试验组UCVA、屈光度优于对照组(P<0.05)。治疗1年后,试验组角膜曲率低于治疗前(P<0.05),试验组角膜曲率低于对照组(P<0.05),对照组治疗前后角膜曲率比较差异无统计学意义(P>0.05)。治疗1年后,试验组眼轴长度与治疗前比较差异无统计学意义(P>0.05),对照组眼轴长度较治疗前增高(P<0.05),试验组眼轴长度低于对照组(P<0.05)。结论:大直径设计角膜塑形镜治疗青少年儿童中低度近视的短期疗效明显,是一种有效的青少年儿童近视控制方法。

Objective:To observe the short-term efficacy of large diameter design orthokeratology lens in the treatment of moderate and low myopia in adolescents and children.Method:A total of 120 adolescents and children of moderate and low myopia treated in our hospital from November 2016 to November 2018 were selected.They were randomly divided into the experimental group and the control group,with 60 cases in each group.The experimental group was given large diameter orthokeratology lens,the control group was given frame glasses.The efficacy was compared between the two groups.Result:After 1 year of treatment,the uncorrected visual acuity (UCVA) was improved and the refraction decreased than those before treatment in the experimental group (P<0.05);in the control group,the UCVA decreased and diopter increased than those before treatment (P<0.05);the UCVA and diopter of the experimental group were better than those of the control group (P<0.05).After 1 year of treatment,the corneal curvature in the experimental group was lower than that before treatment (P<0.05),the corneal curvature of the experimental group was lower than that of the control group (P<0.05),and there was no significant difference in the corneal curvature before and after treatment of the control group (P>0.05).After 1 year of treatment,there was no significant difference in axial length in the experimental group than that before treatment (P>0.05),the axial length in the control group was higher than that before treatment (P<0.05),the axial length of the experimental group was lower than that of the control group (P<0.05).Conclusion:Short-term efficacy of large diameter design orthokeratology lens in the treatment of moderate and low myopia in adolescents and children is significant,it is an effective treatment for controlling myopia development in adolescents and children.
