Pupil capture: prevention and management.

Pupil capture occurs in a small percentage of patients following posterior chamber lens implantation. We noted a 3% incidence in 100 patients using sulcus fixated planar J-loop lenses, a 1% incidence using sulcus fixated angulated J-loop lenses, and a 1% incidence in capsular bag fixated flexible Y-loop lenses. No patients lost vision from pupil capture, and no clinically significant late complications were observed. Pupil capture may be successfully treated in the early postoperative period in some patients by mydriasis and a noninvasive loop compression technique using Q-tips.
