改良后巩膜加固术治疗进展性近视疗效分析

Analysis on curative effects of modified posterior scleral reinforcement surgery for treating progressive myopia

目的 :观察改良后巩膜加固术治疗进展性近视的疗效。方法 :应用硬脑膜材料对 187例近视眼患者 (374只眼 )行改良后巩膜加固术及 2年术后随访 ,其中 16 9例患者(338眼 )有一年以上的完整数据 ,并进入自身对比研究 ,另18例中途失访。结果 :手术一年后 ,平均屈光度为 (- 8.6 8±3.80 )D ,与术前 (- 9.13± 4 .2 3)D相比 ,差异有显著性意义(P =0 .0 13) ,其有效率为 84 .0 %。平均眼轴长度 (2 5 .75± 1.4 5 )与术前 (2 5 .80± 1.4 8)相比 ,变化也有非常显著性意义 (P=0 .0 0 1) ,其有效率为 6 3.3%。结论 :改良后巩膜加固术手术切口小 ,对控制近视的发展疗效确切、安全、简便、不需住院 。

Objective:To investigate curative effects of modified posterior scleral reinforcement surgery for treating patients with progressive myopia.Methods:187 myopia patients(374 eyes) were treated with modified posterior sclera reinforcement surgery using hard meninges and had been prospectively observed for 2 years. Among these patients,unfortunately,18 cases were lost to follow up within one year,and the other 169 cases(338 eyes),who had available records of follow up more than one year,entered the self matched study.Results:One year followings showed that the average of diopters after surgery(-8.68±3.80) was lower than that before surgery(-9.13±4.23) and the effective proportion was 84.0 % on the 338 eyes,as well as the average size of axial after surgery(25.75±1.45) had shorted than that before surgery(25.80±1.48) and the effective proportion was 63.3 % among total eyes.Conclusion:The modified posterior sclera reinforcement surgery is a safe simple and effective treatment progressive myopia patients who could be treated in clinic room rather then in hospital.
