目的：总结角膜塑形镜治疗近视的疗效及影响因素。方法：回顾性病例研究。2006年12月至2009年6月行夜戴型角膜塑形镜（OK 镜）治疗患者共1316例（2534眼），所有患者均夜间配戴8～12h。按照患者就诊时近视度数进行分组：A组446眼，屈光度＜-3．00D ；B组1526眼，屈光度-3．00～-6．00D ；C组562眼，屈光度＞-6．00D。观察其裸眼视力及屈光度变化。数据采用百分数统计和配对t检验进行分析。结果：（1）A 组患者259只眼（58．7％）于1周内均转为正视眼，B组患者738只眼（48．4％）于1个月内恢复为正视眼，C组患者288只眼（51．2％）于1个月内能达到其最佳矫正视力，但均不能达到正视眼；（2）角膜曲率降低范围在1．00～2．75D之间的最多，角膜曲率降低幅度大者近视度数降低也较大；（3）并发症：728只眼（27．7％）角膜点状损伤，适当处理后痊愈；重影的发生率为21．7％。结论：角膜塑形镜对矫治青少年中、低度近视及阻止近视加深有一定的疗效。但须严格掌握其适应证。

Objective :To investigate the therapeutic effect of orthokeratology lenses (OK lenses) for the treatment of myopia and its relevant fac-tors .Methods :In this retrospective study ,OK lenses were applied to 2534 eyes of 1316 patients with myopia .All patients were supplied with night wear 8~12 h lenses and grouped according to degree of myopia :group A ,455 eyes ,refraction ≤ -3 .00 D ;group B ,1470 eyes ,refraction -3 .00D~ ≤ -6 .00D ;group C ,546 eyes ,refraction > -6 .00 D .The patients were analyzed for changes in their uncorrected visual acuity ,refraction ,kera-tometric value ,whether or not there were conjunctival corneal complications ,etc .Results :(1)Refractive change :259 eyes (58 .7 % ) with ≤ -3 .00D became emmetropic within 1 week ;738 eyes (48 .4% ) with -3 .00D ~ -6 .00D became emmetropic ,and 562 eyes with ≥ -6 .25D and 288 eyes (21.4% ) achieved optimal visual correction within 1 month .(2)Keratometric value :The reduction ranged from + 1 .00D to +2 .75D .The lower the keratometric value ,the better the myopia was corrected .(3)Complications :During therapy ,728 eyes (27 .2% ) developed corneal punctal injury .All were cured with proper treatment .The dizzal incidence rate was 21 .7% .Conclusion:The OK lens is effective for treating myopia but the treatment has some limitations .The application must be strictly adhered to .
