角膜塑形术降低近视度和控制近视的有效性和安全性观察

目的 观察角膜塑形术降低近视度和控制近视的有效性和安全性.方法 选择戴角膜塑形镜的68例(136眼)青少年近视患者作为研究组,55例(110眼)戴框架眼镜的青少年近视患者作为对照组,对两组临床资料进行回顾性分析,以评价角膜塑形镜控制近视进展的作用.结果 研究组治疗后裸眼视力较治疗前显著提高(由0.40±0.13升至0.76±0.15),等效球镜和角膜曲率则显著降低[分别由(-3.52±1.25)D降至(-2.63±1.06)D;(43.21±1.28)D降至(42.30±1.25)D],治疗前后比较差异均有统计学意义(P＜0.05)；对照组治疗后等效球镜较治疗前显著提高[由(-3.55±1.27)D升至(-4.65±1.29)D],眼轴亦显著延长[由(24.30±0.53)mm升至(25.16±0.55)mm],治疗前后比较差异均有统计学意义(P＜0.05).研究组治疗期间均无严重角膜感染发生.结论 角膜塑形术可有效降低近视度,减缓眼轴的增长,而且使用方便,安全性高.

The effect and safety of orthokeratology in myopia patients

Objective To observe the effect and safety of orthokeratology in myopia patients.Methods Sixty-eight(136 eyes)young patients with myopia wore orthokeratology lens as research group,and 55 cases(110 eyes)young patients with myopia wore glasses as control group,clinical data of both groups were retrospectively analyzed to evaluate the role of orthokeratology lens on controlling the progression of myopia.Results After treatment,uncorrected visual acuity of research group significantly improved (0.76 ± 0.15 vs.0.40 ± 0.13,P ＜ 0.05),while spherical equivalent(SE)and corneal curvature significantly reduced[(-2.63 ± 1.06)D vs.(-3.52 ± 1.25)D,(42.30 ± 1.25)D vs.(43.21 ± 1.28)D,P ＜ 0.05].After treatment,SE of control group significantly increased[(-4.65 ± 1.29)D vs.(-3.55 ± 1.27)D,P ＜ 0.05],axis oculi significantly prolonged[(25.16 ± 0.55)mm vs.(24.30 ± 0.53)mm,P ＜ 0.05].Research group had no serious corneal infection happened during the treatment.Conclusion Orthokeratology lens can effectively reduce the degree of myopia and slow down the axis oculi growth,and it is used convenient with high security.
