Abstract

Puillary capture in an unusual complication of posterior chamber intraocuIar lens (PCL) implantation and may occur in the early or late postoperative period. An analysis of clinical records was made in 27 pupillary capture cases receiving PCL from Jan 1, 1986 to Mar. 31, 1990. Twenty-two cases (81.5%) were male, and five cases (18.5%) were female. Among the captured PCL, 6.0mm optic and 13.5mm length PCLs were most commonly implanted. All PCLs used in the study had lO degrees angulation of the IOL loops and asymmetric fixation of loop was noted in 5.9% of all pupillary catpure cases. The interval between cataract operation and pupillary capture was variable but most cases (81.5%) of pupillary capture were developed within one year after operation. The subjective symptoms and signs of pupillary capture were decreased vision, glare, double vision, conjunctival injection, tearing and discomfortness while 12 cases (44.4%) had no subjectIve symptoms The reposition of pupillary capture was successfully done by using mydriatics and miotics in 15 of 27 cases (55.6%) and surgical correction was needed in only 2 cases. The recurrence was developed in 53.3% of cases that were corrected with mydriatics Complictions of pupillary capture were iridocapsular or iridolenticular adhesion, atrophy and depigmentation of iris, transient iritis, and pupillary distortion.
