[Identification of cells in deposits on the intraocular lens surface]

We performed posterior chamber lens implantation in a monkey eye and removed the lens on the 14th day after implantation. Cellular deposits on the IOL were observed by a dissecting microscope. Two kinds of cells, large and small, were observed on the lens surface. The large cells constituted the major proportion of the deposits. The same cellular deposits, which were observed by the dissecting microscope, were examined by scanning electron microscopy and then by transmission electron microscopy. The large cells had the structural features of multinucleated giant cells, and the small cells were macrophages.
