Abstract:
We studied the foregin body reaction to the implanted intraocular lens(IOL) and IOL acceptance in the patient's eye by biomicroscopic examination of precipitates on the IOL surface in 432 cases. We divided the cellular and pigment precipitates of the posterior chamber lens(PCL) showed grade 3 until seven days postoperative and then slowly decreased; but, that of the anterior chamber lens(ACL) persisted a little longer. Pigment precipitates on ACL was less than that of PCL, and pigment precipitates stayed longer than cellular precipitates. Round, bipolar small cellular precipitates seem to be identical to fibroblast-like cells, and large, irregular shaped cellular precipitates seem to be foreign body giant cells. A large number of foreign body giant cells precipitated and persisted longer in cases of prolonged postoperative inflammation.
