摘　　要：目的探讨角膜塑形镜对青少年视力发展、眼压、眼轴及角膜地形图的影响。方法回顾性分析2011年8月-2013年6月行角膜塑形镜治疗近视患者100例（180眼），比较其治疗前与治疗后3个月眼睛视力、眼压、眼轴及角膜地形图的变化。结果戴镜前平均视力为球镜（0．21±0．14）D，戴镜后为（0．95±0．12）D；戴镜前平均眼轴长度（24．75士0．81）mm，戴镜后为（24．39±0．79）mm；非接触式眼压计（NCT）测量：戴镜前为（15．43±2．31）mmHg，戴镜后为（13．44±1．95）mmHg；戴镜前后差异均有统计学意义（均P＜0．05）。动态轮廓眼压计（DCT）测量：戴镜前平均眼压为（15．32±4．33）mmHg，戴镜后平均眼压为（14．76±2．08）mmHg，戴镜前后差异有统计学意义（P＞0．05）；治疗后平均角膜平坦K值、角膜表面形状系数、角膜不规则指数与配镜前比较，差异均有统计学意义（均P＜0．05）。结论角膜塑形镜对青少年近视的临床治疗具有疗效确切、见效快等优点，临床应用价值高，值得临床借鉴推广。Objective To discuss orthokeratology lens＇ influence on adolescent＇s vision development , intraocular pressure, axial length and corneal topography. Methods 100 cases of patients（180 eyes） of myopic adolescent patients were accepted retrospective analysis. The vision, intraocular pressure, axial length and corneal topography before t and 3 months after treatment were observed. Results The average visual acuity before wearing orthokeratology lens was （0.21 ±0.14） D, after wearing orthokeratology lens was （0.95 ±0.12） D. The average axial length before wearing was （24.75 ±0.81） mm, the mean axial length after wearing was （24.39 A±0.79） ram; Non-contact tonometer （NCT） measurements： mean IOP before wearing before was （15.43±2.31） mmHg, the mean IOP after wearing was （13.44±1.95） mmHg; there were significant differences （P〈0.05） in above items before and after wearing glasses. Dynamic contour tonometer （DCT） measurements： mean IOP before wearing orthokeratology lens was （15.32 ±4.33） mmHg, after wearing was （14.76±2.08） mmHg, there were significant difference （P〉0.05） before and after wearing orthokeratology lens; the average K value flat cornea after treatment, corneal surface shape factor, corneal irregularity index glasses obvious difference with the former, with statistical significance （P〈0.05）. Conclusion Orthokeratology lens for clinical treatment of juvenile myopia has efficacy, quick, and other advantages.
