目的探讨YAG激光“环形”切开法在儿童后发障中的应用。方法应用Nd:YAG激光对36例39眼儿童后发性白内障进行治疗,所有病例均用单脉冲,激光能量为1.6～2.6mJ,平均2.1mJ;脉冲次数10~29次,平均17.5次,总能量为21～80mJ,平均为55mJ。所有病例均随访3月以上。结果36例39眼全部一次成功,视力有所提高,并发病少。结论该方法操作简单,不易损伤人工晶体光学区,安全有效。 Objective To investigate the application of YAG laser “ring” incision method in posterior capsulitis in children. Methods Thirty-six children (39 eyes) with cataract treated by Nd: YAG laser were treated with single pulse. The laser energy was 1.6-2.6 mJ (average 2.1 mJ), pulse number was 10-29 times (mean, 17.5) Energy is 21 ~ 80mJ, with an average of 55mJ. All cases were followed up for more than 3 months. Results 36 cases of 39 eyes all succeeded, visual acuity improved, with less incidence. Conclusion The method is simple and easy to damage intraocular lens optical zone, safe and effective.
