目的探讨瞳孔环形黏连的白内障超声乳化术的手术技巧及效果。
4眼瞳孔撕裂散大，3眼虹膜部分缺损，所有患眼均未造成虹膜前粘连。
1·The second was nasal synechia(33/131), the chosen factors were total dose of external irradiation, intracavitary irradiation and medicamentous rhinitis.
其次是鼻粘连（33/ 131） ，选入的因素有鼻咽腔外照射总剂量、鼻咽腔内照射、药物性鼻炎；
2·The main postoperative complications were anterior uveitis and posterior synechia of the iris.
术后主要并发症是前葡萄膜炎和虹膜后粘连。
3·The increase of IOP after the NPTS is related to the fibrous thickening of the filtration membrane in the operation area and the peripheral anterior synechia.
术后眼压升高，除滤过泡瘢痕化因素外与手术区滤过膜的纤维化增厚及虹膜周边前粘连导致房水滤过减少密切相关。
4·Methods a single pulse YAG laser was used to relieve the iris synechia and blow up the membrane on anterior surface of IOL.
方法YAG激光单脉冲先切除前膜与虹膜的粘连，再将人工晶状体表面前膜粉碎性切除。
5·Results:The rate of posterior synechia because of long term use of miotic is 46.7%.
结果：长期用缩瞳剂造成虹膜后粘连的发生率为46 .7% ；
