Histopathologic and scanning electron microscopic study of one type of intraocular lens.

We performed clinicopathologic analyses of 28 explanted anterior chamber intraocular lenses (Stableflex). Two factors strongly indicated that this lens can be difficult to remove: (1) the clinical histories obtained from the explanting surgeons who, with few exceptions, stated that removal was extremely difficult; and (2) our scanning electron microscopic findings, which documented extensive tissue encapsulation around loops as well as multiple sites of loop severance required at the time of lens removal. The general efficacy of this intraocular lens compared with other anterior chamber lenses was not addressed in this study.
