摘要
目的 评价角膜塑形术 (Orthokeratology ,Ortho -k)治疗近视眼的疗效。方法 采用角膜塑形术对98例 (192眼 )近视眼患者进行治疗 ,观察视力、屈光度、角膜曲率的变化。结果 治疗 3月 ,与治疗前比较 ,近视度数最多可降低 5 75D ,规则散光可降低 2 75D。低度近视组 96 4 7%恢复正视眼 ,中高度近视组 6 4 6 9%恢复正视眼。眼球屈光度的降低与角膜曲率的减少呈正相关 (γ =0 993,P <0 0 0 0 5 ) ,性别、年龄与疗效无明显关系 ,无严重并发症发生。
Objective To evaluate the effectiveness of orthokeratology (Ortho-k) in treatment of myopia. Method Using Better Vision Contact lenses to treat 98 patients with myopia(192 eyes). The visual, the diopter of myopia and the corneal curvature were observed.Results Three monthes after treatment the myopia degree was reduced by-5 75D,astigmatism with rale was decreased by-2 75D,respectively,96 47% of low myopia (≤-3 00D),64 49% moderate-high myopia (-3 00D～-7 25D) were recovered to emmetropia. A positive correlation was found between the spherical equivalent and the corneal curvature (γ=0 993,P<0 0005).The efficacy was no obviously related to the age and sex. For all patients, no serious complication was occured. Conclusion Orthokeratology is so far an effective non-surgical way for myopia treatment.
