角膜塑形镜对青少年近视的干预效果

Effect of Orthokeratology Lens on Adolescent Myopia

目的:探讨角膜塑形镜在青少年近视干预中的应用效果。方法:将我院眼科收治的120例(210眼)近视青少年随机分为C组60例(100眼)和J组60例(110眼),分别行常规配戴框架眼镜干预和角膜塑形镜干预。干预前后检测视力参数和视觉质量。结果:在视力参数上,干预3、6、12个月,J组屈光度和角膜曲率均优于C组(均P<0.05);干预12个月,J组裸眼视力和眼轴长度均优于C组(均P<0.05)。在视觉质量上,干预3、6、12个月,J组调制传递函数截止频率(MTF cutoff)与客观散射指数(OSI)均优于C组(均P<0.05)。结论:青少年近视治疗中采用角膜塑形镜干预能有效改善视力和视觉质量,效果优于常规框架眼镜。

Objective:To investigate the application effect of orthokeratology lens on adolescent myopia.Methods:A total of 120 myopic adolescents(210 eyes)treated in our hospital were randomly divided into the group C(60 cases with 100 eyes)and the group J(60 cases with 110 eyes).Visual parameters and visual quality were measured before and after intervention.Results:In terms of visual acuity parameters,the diopter and corneal curvature were better in the group J than those of the group C at 3,6 and 12 months after intervention(all P<0.05).The uncorrected visual acuity and axial length were better in the group J than that of the group C at 12 months after intervention(both P<0.05).In terms of visual quality,the modulation transfer function cutoff frequency(MTF cutoff)and objective scatter index(OSI)were more excellent in the group J than those of the group C at 3,6 and 12 months after intervention(all P<0.05).Conclusion:Orthokeratology can effectively improve the visual acuity and visual quality in the treatment of adolescent myopia,which is better than conventional frame glasses.
