A histopathologic study of the Choyce VIII intraocular lens.

We performed a postmortem ocular examination on a 52-year-old man who had had Choyce VIII intraocular lenses implanted in both eyes. Visual acuity with both lenses was 6/6 (20/20). There were no clinical complications before the patient's death. Marked stretching of the chamber angle occurred at all points of fixation, with ultimate loop fixation into the substance of the ciliary body and, in some instances, erosion close to the greater arterial circle of the ciliary body. Where iris tucking had occurred, the iris tucked over the foot of the lens was extremely thin with the foot and the tucked iris in the pars ciliaris region.
