目的:探讨用532激光联合Nd∶YAG激光松解虹膜后粘连的可行性及疗效评价。方法:对各种原因所致的虹膜后粘连97例116眼分别用单用Nd∶YAG激光、单用532激光及二者联合3种方法进行击射以松解虹膜后粘连。结果:患者116眼经激光解除粘连使瞳孔散大至直径≥6mm者92眼(79.3%);5～6mm者24眼(20.7%)。粘连全部解除瞳孔圆者86眼(74.1%);粘连大部分解除,瞳孔不圆者30眼(25.9%)。单用Nd∶YAG激光虹膜后粘连松解术者18眼,术后瞳孔扩大直径≥6mm者12眼(66.7%),5～6mm者6眼(33.3%);单用532激光61眼,术后瞳孔扩大至直径≥6mm者52眼(85.2%),5～6mm者9眼(14.8%);532激光联合Nd∶YAG激光虹膜粘连松解术37眼,术后瞳孔散大至直径≥6mm者33眼(89.2%),5～6mm者4眼(10.8%)。结论:虹膜后粘连激光松解术是一种安全有效的方法,值得推广。

AIM:To evaluate the feasibility and efficacy in lysis of posterior synechia by 532 laser combined with Nd∶YAG laser.METHODS: Ninety-seven patients 116 eyes of posterior synechia were divided into three groups: Nd∶YAG laser group, 532 laser group and combined both group. Three kinds of method in order to loosen posterior synechia.RESULTS: Synechia in 116 eyes were dissolved by laser,the pupil diameter ≥ 6mm (n=92 ) accounted for 79.3%; 5-6mm (n=24) accounted for 20.7%. All the pupil adhesions were dissolved accounting for 74.1% (n=86); most of the pupil adhesions were dissolved in 30 eyes accounting for 25.9%. Nd∶YAG laser group (n=18): pupl diameter ≥6mm in postoperation was in 12 eyes accounted for 66.7%, 5-6mm was in 6 eyes accounted for 33.3%; 532 laser group(n= 61): the pupil diameter ≥6mm in postoperation was in 52 eyes accounted for 85.2%, 5-6mm was in 9 eyes accounted for 14.8%; 532 laser combined with Nd∶YAG laser group (n=37) : pupil diameter ≥6mm in postoperation was in 33 eyes accounted for 89.2%, 5-6mm was in 4 eyes accounted for 10.8%.CONCLUSION: Laser lysis is a safe and effective method for posterior synechia.
