Abstract

Objective To observe the efficacy of orthokeratology lens for the control of myopia of juvenile. Methods A total of 64 eyes of 64 cases of anisometropia who wear orthokeratology lens monocularly from Jan.2015 to Dec.2016 in this hospital were analyzed retrospectively. All patients aged from 9 to 15 years. The follow-up time was two years.All cases were divided into the wearing orthokeratology lens group and non-wearing group. Results The rate of patients with myopic diopter increased≥1.00 D in the wearing group were significantly lower than those of non-wearing group(χ2=57.134, P=0.000). The increased myopic diopter in wearing group (0.61±0.18)D was lower than that in non-wearing group (1.49±0.37)D(t=-16.719, P=0.000). The growth of axial lengths was (0.32±0.22) mm in wearing group, which was lower than that(0.71±0.27) mm in non-wearing group (t=-5.831, P=0.000). Conclusion The efficacy of orthokeratology lens for control of myopia in juvenile is better than the non-wearing eyes for the same individual, indicating that orthokeratology lens could effectively control the development of myopia. Key words: Orthokeratology; Diopter, myopia; Length, axial

角膜塑形镜控制青少年近视的疗效观察

目的观察角膜塑形镜控制青少年近视的效果。方法回顾性分析我院2015年1月至2016年12月64例单眼配戴角膜塑形镜的屈光参差患者64只眼。所有患者年龄在9至15岁之间。随访时间为两年。所有病例分为配戴角膜塑形镜组和不配戴组。结果配戴组患者近视度数≥1.00 D的比例明显低于未配戴组(χ2=57.134, P=0.000)。配戴组近视屈光度增加(0.61±0.18)D低于未配戴组(1.49±0.37)D(t=-16.719, P=0.000)。磨损组的轴向长度增长为(0.32±0.22)mm，低于未磨损组的(0.71±0.27)mm (t=-5.831, P=0.000)。结论角膜塑形镜对青少年近视的控制效果优于非配戴者，说明角膜塑形镜能有效控制近视的发展。关键词:角膜塑形术;近视屈光度;长度、轴向
