[Pupil capture of the posterior chamber intraocular lens: cause and management].

Pupil capture is a rare complication in posterior chamber intraocular lens implantation. Among 259 eyes with PC IOLs, pupil capture was noted in 6 eyes (2.3%), all J-loop planar lenses (6/119 or 5%), while none of the other 140 eyes with angled or modified J-loop lenses had pupil capture. The complication was successfully corrected by a loop compression maneuver through the sclera, and the patients had visual acuities over 1.0 on follow-up. Based on clinical observations and an experimental model, it was presumed that the arching forward of planar lenses could be the major cause of pupil capture.
