目的:评价角膜塑形术对近视的治疗效果。方法:30例(58眼)依屈光度不同分Ⅲ组(—1.75D～—3.00D,—3.25D～—5.00D,—5.25D～—9.00D)分别进行角膜塑形镜治疗,记录治疗前后屈光度、角膜曲率的变化。结果:Ⅲ组屈光度均下降,以第Ⅰ、Ⅱ组明显,角膜屈率变小,治疗前后相比差异有显著性(P<0.05)。结论:角膜塑形镜对治疗—5.00D以下近视有效,并发症少,但停戴后有反弹,远期疗效有待进一步观察。 Objective: To evaluate the effect of orthokeratology on myopia. Methods: Thirty patients (58 eyes) were divided into three groups according to diopter (-1.75D ~ -3.00D, -3.25D ~ -5.00D, -5.25D ~ -9.00D) Diopter, corneal curvature changes. Results: The diopter of group Ⅲ was decreased, especially in group Ⅰ and group Ⅱ, and the rate of corneal flexion became smaller. There was significant difference between before and after treatment (P <0.05). Conclusion: Orthokeratology is effective in treating myopia of -5.00D or less with less complications, but there is a rebound after stopping wearing. The long-term curative effect needs to be further observed.
