Delayed glaucoma after implantation of a Choyce intraocular lens.

A Choyce intraocular lens was inserted nine years after a routine intracapsular lens extraction. A year after this second operation, an acute pupil block glaucoma developed. Three weeks after the onset of the glaucoma, repeated laser iridotomies controlled the glaucoma. Pupil block glaucoma may be a complication long after intraocular lens implantation.
