Fibroblast-like cells on intraocular lens implants: phagocytosing erythrocytes

An intraocular lens implant had to be removed 4 years after its implantation from the eye of a patient on warfarin (Coumadin) medication because of repeated intraocular haemorrhages. Implant cytology staining revealed a continuous membrane on the removed implant that contained relatively few large foreign body giant cells and great numbers of small fibroblast-like cells. An impressive clean-up function of the fibroblast-like cells with phagocytosis of whole erythrocytes was observed.
