We compare the intraocular reaction to posterior chamber lens implants placed inside, with the reaction to implants placed outside the capsular bag during uncomplicated cataract extraction. Two otherwise normal eyes were obtained postmortem from a 93-year-old woman with clinically successful posterior chamber lens implants--one mostly in and the other outside of the capsular bag. While all parts of one implant in the bag were found to be free of reactive elements on their surface, the other whole implant and the one haptic outside of the bag were covered by a well-developed reactive membrane composed of a proteinaceous film with sessile macrophages and a few giant cells. Despite these remarkably different surface reactions, both eyes showed about equal pathologic evidence of associated chronic uveitus.
我们比较了在无并发症的白内障摘除术中，眼内对置于囊袋内的后房型人工晶状体植入物的反应与对置于囊袋外的植入物的反应。从一名93岁女性尸检中获得了两只在临床上后房型人工晶状体植入成功的正常眼睛——一只人工晶状体大部分位于囊袋内，另一只位于囊袋外。发现囊袋内一只人工晶状体的所有部分表面均无反应性成分，而另一只完整的人工晶状体以及位于囊袋外的一个袢被一层发育良好的反应膜覆盖，该反应膜由含有固定巨噬细胞和一些巨细胞的蛋白质膜组成。尽管表面反应存在显著差异，但两只眼睛显示出的相关慢性葡萄膜炎的病理证据大致相同。
