摘　　要：目的:观察角膜塑形镜矫正青少年近视的有效性及安全性。方法:通过对178例356眼佩戴角膜塑形镜定期的复查跟踪,观察其复查裸眼视力,及2年后度数增长,在1个月、3个月、半年、1年、2年的角膜前水平曲率值,垂直曲率值,中央角膜厚度、角膜内皮计数及眼压的改变。结果:角膜塑形镜能提高裸眼视力,控制度数的发展,治疗后1天有54.87% ≥1.0,1个月时;有99.14% ≥1.0;3个月时,100% ≥1.0,停戴2周后复查屈光度,降低0.25D^0.75 D的有56眼占17.95%,不变的194眼占62.18%,增高0.25~0.50 D者60只眼约占19.23%,2只眼增高0.75 D,在1个月、3个月、半年、1年及2年其中央角膜厚度、角膜内皮计数及眼压较佩戴前无明显差异(P >0.05),角膜曲率较佩戴前变平坦,有统计学意义(P 0.05)。结论:在正规的验配、正确的配戴及保养镜片下,使用角膜塑形镜控制青少年近视的发展是安全有效的。Aim: To observe the effect and safety of orthokeratology contact lenses for rectifying myopia and controlling the development of myopia. Methods: By studying retrospective case series, the myopia of 178 cases (356 eyes) was corrected by orthokeratology contact lenses and the changes of visual acuity, corneal curvature, the central corneal thickness, corneal endothelium and corneal conjunctival complications rate were all improved. The youth myopia patients were followed up at 1 month, 3 months and 6 months, 1 year, 2 years respectively and Ocular surface health was ex-amined by slit-lamp microscope. Results: Orthokeratology contact lenses can reduce myopia sig-nificantly and control degree development. A day later, there are about 54.87% the visual acuity ≥1.0;a month later, about 99.14% ≥1.0;3 months later, about 100% ≥1.0. After 2 weeks without using orthokeratology, 56 eyes were decreased by 0.25D - 0.5D accounted for 17.95%, unchanged in 194 eyes accounted for 62.18%,60 eyes were increased 0.25D - 0.50D accounted for 19.23%, only two eyes were increased 0.75D. There were no remarkable complications in the ocular surface. There were no significant changes in corneal thickness, corneal endothelia and intraocular pressure after two years Ortho-K CL wear (P >0.05). Central curvature flattening was observed. Conclusion: Orthokeratology regarded as a non-traumatic way to rectify myopia can reduce diopter and control the development of myopia effectively.
