Anticoagulation, intraocular bleeding and pupillary paralysis following Choyce intraocular lens implantation.

Four cases of pupillary paralysis are presented which followed implantation of the Surgidev version of the Choyce Mark VIII implant. In three of these cases the lenses were removed. Of the four cases, two had been anticoagulated and showed massive vitreous or anterior chamber hemorrhages, the appearance of which was related by time, or in severity, to the anticoagulation with coumadin.
