title: Anterior tucking of the iris caused by posterior chamber lenses with polypropylene loops.
abstract: One hundred ten eyes that had extracapsular cataract extraction with posterior chamber lens implantation were examined gonioscopically to ascertain the frequency of anteriorly displaced polypropylene loops "tucking" into the posterior iris surface. The association with iris transillumination defects and the development of postoperative uveitis, hyphema, and raised intraocular pressure were also recorded. Sixty-six eyes (60%) had one or two anteriorly tucked loops; 28 of them (25%) had some associated iris transillumination defect related to the implant. Twenty eyes (18%) developed persistent postoperative uveitis; 15 of them had anteriorly tucked loops. Two eyes had postoperative hyphema and in both these eyes the loops were anteriorly tucked. The means of recognizing and preventing potential complications are discussed.
