[Cellular reactions after intraocular lens implantation]

The surgical trauma and the presence of the artificial lens in the eye causes inflammatory reactions. The cellular response is a result of 1) the breakdown of the blood-aqueous barrier, 2) foreign body reaction induced by lens material. The presence of cellular deposits (small, fibroblast-like, epithelioid, giant cells) on the surface of intraocular lenses is related to many factors such as surgical technique, risk factors of inflammation, postoperative treatment and the kind of lens material. The aim of this paper is to present contemporary knowledge about cytopathology of intraocular lenses and chances to improve the surface characteristic to avoid the adhesion of cells.
