摘要
目的:探讨白内障手术行虹膜爪植入术患者的术前、术中指征、术后并发症、继发性青光眼的发生率、视力状况及玻璃体切除术对术后眼压的影响。材料与方法:2016年1月至2020年2月进行回顾性研究。187例行虹膜爪晶状体植入术的患者187只眼,随访至少1个月。分析术前、术中发现的记录,并记录术后最佳矫正视力(BCVA)和IOP。结果:187只眼术前BCVA均值为1.78 logMAR (SD 0.68),术后第1天、第7天、第1个月BCVA均值分别为0.61±0.50、0.36±0.26、0.21±0.16 logMAR。最常见的适应症包括瞳孔缩小(17.65%)、小扩张和不扩张瞳孔(11.22%)、带状透析(6.41%)和假脱落(4.81%)。少数患者(6.94%)术前存在角膜病变,导致术中并发症,导致虹膜爪状植入术。术后1个月玻璃体切除眼的平均IOP为15.53 (SD 2.16) mm Hg,未切除眼的平均IOP为16 (SD 1.90) mm Hg。手术中最常见的指征是后囊膜撕裂和全囊袋丢失。继发性青光眼的发生率为2.13%。不规则瞳孔是术后1个月最常见的前节发现。结论:瞳孔后虹膜爪植入术是一种安全、简单的术中并发症处理方法,能使患者获得良好的视力,避免多次手术的创伤。
Aim: To evaluate the preoperative and intraoperative indications, postoperative complications, incidence of secondary glaucoma, and visual outcome in patient who underwent iris-claw implantation during cataract surgery and effect of vitrectomy on postoperative intraocular pressure (IOP).
