Direct vitreous reaction to intraocular lens implants.

Three intraocular lens implants removed during keratoplasty between 1 1/2 and 5 years after implantation revealed attachments of reactive vitreous strands and membranes contained bundles of fibers with associated small bipolar cells, pigment, and blood remnants. Some of the fibrous vitreous strands were wound around the haptics of the implants for firm anchoring. The usual reactive cell membranes on the surface of the implants were interrupted in the areas of the attachment of formed vitreous and vitreous membranes.
