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 ,可在门诊广泛开展
Objective: To observe the therapeutic effect of modified scleral reinforcement on progressive myopia. METHODS: 187 patients with myopic eyes (374 eyes) underwent scleral reinforcement and 2-year postoperative follow-up with dural material. Of these, 169 patients (338 eyes) had more than one complete set of data and entered self-contrast Study, and the other 18 cases were lost to midway. Results: After one year of operation, the average refraction was (8.68 ± 3.80) D, which was significantly different from that before operation (- 9.13 ± 4.23) D (P = 0.013) The effective rate is 84.0%. The mean axial length (25.5 ± 1.4) was also significantly different from preoperative (25.8 ± 1.4) (P = 0.010), with an effective rate of 6 3.3 %. Conclusion: The sclerectomy improved surgical incision is small, the control of the development of myopia is effective, safe, simple, without hospitalization, can be widely carried out in the clinic
