Fibrinoid reaction after extracapsular cataract extraction and relationship to exfoliation syndrome.

A transitory deposit of a fibrin-like material in the anterior chamber following extracapsular cataract extraction and intraocular lens (IOL) implantation is described. In two studies, one retrospective of 352 operations and one prospective of 189 operations, the fibrinoid reaction was observed in 17% and 11% of the eyes, respectively. The reaction appeared in the early postoperative period in an otherwise quiet eye and the signs varied from a few threads in the pupil area to a dense pupillary membrane in front of the IOL.
