Abstract

Objective To observe the effect of OK lens correct and prevent myopia in school-age children. Methods A retrospective case-cohort study of 206 eyes ofschool-age children with myopia received treatment,which were divided into OK lens group 106 eyes and frame lens group of 100 eyes. The changes of UCVA,AL,SE and corneal curvature were analyzed. Results UCVA of OK lens group began to improve after 1day, improved obviously after 1month (P <0.05),1-6months UCVA tended to be stable;SE and corneal curvature decreased after 1day, decreased obviously after 1month (P <0.05). Compared with the frame lens group, the AL and SE increased after 1 day, but the growth rate was slow and the difference was statistically significant(P <0.01). Conclusions The OK lens is effective in correcting the myopia of school-age children, and it has a certain delay effect on the progression of myopia. Key words: Orthokeratology lens; School-age children; Spherical equivalent; Ocular axial length; Corneal curvature

角膜塑形镜矫正学龄儿童近视的近期效果

目的观察OK晶状体矫正和预防学龄儿童近视的效果。方法对206例接受治疗的学龄近视儿童进行回顾性病例队列研究，分为OK晶状体组106眼和框架晶状体组100眼。分析UCVA、AL、SE和角膜曲率的变化。结果OK晶状体组UCVA在1天后开始改善，1个月后明显改善(P <0.05)，1-6个月UCVA趋于稳定;SE和角膜曲率在1天后下降，1个月后明显下降(P <0.05)。与框架透镜组相比，AL和SE在1 d后升高，但增长速度较慢，差异有统计学意义(P <0.01)。结论OK晶状体矫正学龄儿童近视效果显著，对近视的发展有一定的延缓作用。关键词:角膜塑形镜;学龄儿童;球形等效;眼轴长;角膜曲率
