Formation of proteinaceous capsules on plastic lens implants--by mouse macrophages under tissue culture conditions.

Formation of continuous proteinaceous capsule-like layers is demonstrated in tissue culture on plastic lens implants as part of cellular membranes created by mouse macrophages after 48, 56, and 96 hours of incubation. The capsules resemble similar formations seen on lens implants removed from human eyes and their existence is considered part of a clinically beneficial adaptation of man-made materials to the inner eye.
