Surface reaction on a posterior chamber lens seven days after implantation

Seven days after extracapsular cataract extraction and intraocular lens implantation, a posterior chamber lens was removed following the patient's sudden death. The lens was studied with the implant cytology technique, which demonstrated a continuous and optically clear separating film of proteinaceous nature. The film was fully developed and covered the entire implant. A few macrophages were found in one area on the surface of the otherwise acellular film; these were involved in blood phagocytosis and did not appear to have been involved in the formation of the acellular proteinaceous film.
