虹膜后粘连白内障人工晶状体植入术

Intraocular lens implantation in cataract cases with posterior synechia.

目的 探讨伴虹膜后粘连的人工晶状体植入术的手术方法及效果。方法 对 19眼行虹膜根部切除 ,并通过根切口及下方角膜缘辅助切口分离粘连 ,放射状瞳孔缘切开 ,前段切割器顺序切除已切开的呈锯齿状瞳孔缘虹膜组织行瞳孔成形。截囊完成后房型人工晶状体的植入。结果 19眼经上述方法均完成人工晶状体的植入 ,瞳孔保持基本圆形 ,17眼 (89 5 % )视力改善。结论 对后粘连及小瞳孔只要进行适当处理 。

Objective To evaluate surgical technique and postoperative effectiveness in intraocular lens implantation cases with posterior synechia.Methods 19 eyes(19 cases)were performed with iridectomy at first procedure,through the opening of iridectomy and lower limbus assistant incision seperating posterior synechia,making radial small cuts at pupillary margin,undertaking iridoplasty by using anterior vitrectomy cutter to smooth the saw toothed pupillary margin,and using capsulotomy technique to fulfil the IOL implantation.Results 19 eyes were wellperformed with IOL implantation,round pupils were well remained postoperativly,vision improved in 17 cases.Conclusion IOL implantation could be finished successfully and postoperative good effectiveness could be achieved if managements to small pupil with posterior synechia were performed properly
