For two and a half years this 99-year-old man had done well with his anterior chamber lens of the Choyce type. He donated the eye for pathological evaluation after his death. The eye exhibited some superior corneal edema, distortion of the lower iris with formation of pockets to hold the inferior feet of the implant, some iris atrophy, slight iritis, minimal bleeding, slight neovascularization, and vacuolic degeneration of the pigment epithelium. The observation of a callus-like formation of connective tissue on all those parts of the iris surface that have had contact with the lens implant is the most important finding. This indicates that the iris can not only adjust to the foreign substance of the implant, but it can also give it firm and lasting support. The authors suspect a mild stage of cystoid macular edema with fibrinous exudation into vitreous and preretinal spaces to be present in this case.
这位99岁的男性使用乔伊斯（Choyce）型前房晶状体两年半，情况良好。他死后捐献了眼睛用于病理评估。该眼睛表现出一些角膜上部水肿、下部虹膜变形并形成囊袋以容纳植入物的下脚、一些虹膜萎缩、轻度虹膜炎、少量出血、轻度新生血管形成以及色素上皮的空泡变性。最重要的发现是在虹膜表面所有与晶状体植入物接触的部位观察到结缔组织的胼胝样形成。这表明虹膜不仅可以适应植入物的异物，还可以给予其牢固而持久的支撑。作者怀疑该病例存在轻度的黄斑囊样水肿，并伴有纤维蛋白渗出到玻璃体和视网膜前间隙。
