摘　　要：目的:探讨角膜塑型术(Ortho-K镜)对近视矫正的作用及控制近视发展的长期效果。方法:对200例配戴Ortho-K镜满6年的青少年近视患者的临床资料进行分析,以了解其相关指标的变化情况。200例386只眼配戴前裸眼视力0.31±0.21,屈光度-3.81±2.78 D,角膜曲率44.51±3.53,BUT时间18.28±8.14 s,眼压值2.13±0.67 kPa,内皮细胞计数2 859±851,角膜中央厚度544±68μm。结果:随访6年未见严重并发症发生,患者视力得到显著提升(P<0.05),屈光度和角膜曲率比较有显著性降低(P<0.01),角膜内皮细胞计数和角膜中央厚度未见明显改变(P>0.05)。结论:角膜塑型术作为一种非创伤性矫正近视的手段,能有效降低近视屈光度,控制近视发展。Objective： to investigate the effect of Orthokeratology（ Ortho - K for short） rectifying myopia and long - term effect of controlling the development of myopia. Methods： Children had been observed with Ortho - K lasting above 6 years, 200 patients（386 eyes）, whose average age was 14. 3, bare vision was 0. 31±0. 21 before wearing Ortho - K, dioptre is - 3.81 ± 2. 78D ; corneal curvature is 44. 51 ± 3.53 ; time of BUT is 18. 28 ± 8. 14 s ; numbers of endothelium is 2 859±851 ;and the central thickness is 544 ±68 μm. Results：No serious complication happened on people,whose dioptre and corneal curvature was reduced obviously,and patients vision was promoted dictinctly,and the time of BUT and ocular pressure decreased obviousely,and the bumbers of corneal endothelium and corneal central thickness did not change evidently. Conclusions： Ortho - K as a non - traumatic way of rectifying myopia,can reduce dioptre and control the development of myopia effectively.
