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。结论 角膜塑形术是较有效的非手术矫治近视的方法
Objective To evaluate the efficacy of Orthokeratology (Ortho-k) in the treatment of myopia. Methods 98 patients (192 eyes) with myopia were treated with orthokeratology. Visual acuity, refraction and corneal curvature were observed. Results of treatment in March, compared with before treatment, myopia can reduce the maximum 575D, the rules of astigmatism can reduce 2 75D. Low myopia group 96 4 7% to restore eyes, middle and high myopia group 6 4 6 9% to face up eyes. There was a positive correlation between reduction of corneal curvature and corneal curvature (γ = 0 993, P 0 100 05). There was no significant relationship between sex, age and curative effect, and no serious complication occurred. Conclusion Orthokeratology is a more effective non-surgical correction of myopia
