摘 要 本文讨论了二期人工晶体植入术的适应证、手术方法及视力预后。方法:51例52只眼行二期人工晶体植入术,28只眼为后房型人工晶体植入,其中8只眼为人工晶体缝线固定术;24只眼为前房型人工晶体植入。结果:术后随访6~42个月,平均14个月,术后最佳矫正视力≥0.5者34只眼(65.4%),术后最佳矫正视力≥术前最佳矫正视力39只眼(75%)。并发症为人工晶体倾斜、继发性青光眼、视网膜脱离、前房出血和前房积脓。结论:二期人工晶体植入是安全有效的。新型弹性开放袢一体型前房型人工晶体具有操作简便、术后反应轻、并发症少的优点,是后房型人工晶体二期植入的重要补充。

this study was to investigate the indication,surgical methods and visual acuity prognosis of se-condary intraocular lens implantation,secondary intraocular lens implantation was performed on 51 patients(52 eyes).28 eyes received posterior chamber lenses. 8 of which had scleral suture fixation.24 eyes received one-piece flexible open-loop anterior chamber lenses.The best corrected postoperative visual acuity was≥0.5 in 34 eyes(65.4%)and the postoperative visual acuity was better than that of preoperation in 39 eyes(75%)during a follow-up of 6-42 months with an average of 14 months.The complications included lens tilt,secondary glaucoma,retinal detachment,hyphema and hypopyon.Our results showed that secondary intraocular lens implantation was safe and effective.The use of one-piece flexible open-loop aC-IOLs had the advantages of easy operation,slight postoperative reaction and less complication.

由于病情、手术技术、设备和经济条件等各种原因,有部分患者不能在白内障摘出的同时一期植入人工晶体。为了能最大限度恢复无晶体眼的正常光学生理状态,二期人工晶体植入作为矫正无晶体眼的重要方法之一,受到临床普遍重视。现将我院51例52只眼二期人工晶体植入术及其临床观察报告如下。
1 资料与方法
1.1 对象 本组51例52只眼,男47例48只眼,女4例4只眼,年龄11~73岁,平均35.8岁。外伤性白内障术后35只眼,老年性白内障囊外摘出术后13只眼,囊内摘出术后1只眼,先天性白内障吸出术后3只眼。无晶体眼时间3个月~13年,平均3.3年。术前最佳矫正视力≥0.5者33只眼(63.5%)。多数眼伴有1种或几种前节结构紊乱,其中后囊不完整23只眼,后发障激光打孔6只眼,粘连性角膜白斑8只眼,瞳孔后粘连20只眼,虹膜缺损9只眼,瞳孔变形或移位9只眼。
1.2 方法 20只眼为二期后房型人工晶体植入术,8只眼为双襻经巩膜人工晶体缝线固定术,24只眼为二期前房型人工晶体植入,均使用新型弹性开放襻一体型PMMA前房型人工晶体(Storz S121UV型)。术中行前部玻璃体切割或前玻璃体剪除者9只眼,前节成形包括瞳孔成形,虹膜前、后粘连松解、后囊膜切开等23只眼。术后随访时间6~42个月,平均14个月。
