目的 探讨夜戴型角塑形镜对青少年近视眼视力、屈光度、眼轴、泪膜的影响.方法 随机选取我院佩戴角膜塑形镜患者60例 (116眼) , 比较戴角膜塑形镜前与戴镜后1周、1个月、3个月、6个月和1年视力、屈光度、眼轴及泪膜变化.结果 戴角膜塑形镜1周裸眼视力较戴镜前提高[ (0.45±0.07) vs (0.43±0.07) ], 差异有统计学意义 (P＜0.05) ;平均屈光度较戴镜前下降[ (180.71±35.99) D vs (182.86±36.65) D], 泪膜破裂时间较戴镜前缩短[ (7.71±0.74) s vs (7.99±0.65) s], 差异有统计学意义 (P ＜0.05) ;眼轴较戴镜前未见明显变化 (P＞0.05) ;其后戴角膜塑形镜1个月、3个月、6个月和1年分别与戴镜前比较, 视力、屈光度、眼轴及泪膜变化均呈稳定趋势.结论 角膜塑形镜可控制近视度数并提高裸眼视力, 延缓视轴增长, 对青少年近视控制效果明显, 泪膜损伤小, 安全可靠.%Objective To investigate the effects of night-wearing angle-shaping mirror on visual acuity, diopter, axial length and tear film in adolescent myopia. Methods A total of 60 patients (116 eyes) who underwent Orthokeratology in our hospital were randomly selected. One-week, one-month, three-month, six-month and one-year visual acuity and diopter were compared before and after wearing keratoplasty. Eye axis and tear film changes.Results 1 week of keratoplasty was improved compared with that before wearing [ (0.45 ±0.07) vs (0.43 ±0.07) ], the difference was statistically significant (P＜0.05) ; the average diopter decreased compared with that before wearing [ (180.71± 35.99) D vs (182.86±36.65) D], the tear film rupture time was shorter than that before wearing [ (7.71±0.74) s vs (7.99±0.65) s], the difference was statistically significant (P＜0.05) ; There was no significant change before wearing glasses (P＞0.05) ; after wearing Orthokeratology, 1 month, 3 months, 6 months and 1 year, respectively, compared with wearing glasses, vision, diopter, eye axis and tears Membrane changes showed a steady trend. Conclusion The Orthokeratology can control the degree of myopia and improve the visual acuity of the naked eye, delay the growth of the visual axis, and have obvious effect on the control of myopia in young people. The tear film damage is small, safe and reliable.
