In the first case, pseudophacodonesis secondary to zonular laxity from pseudoexfoliation syndrome caused chafing of the posterior iris by the square-edged haptic. In the second case, focal capsular fibrosis around the square-edged haptics combined with anteriorly rotated ciliary processes in plateau iris configuration caused points of chafing. Extensive capsular fibrosis of the haptic in both cases precluded IOL exchange. In the first case, a capsular tension ring redistributed zonular tension and reduced symptoms. In the second case, endoscopic cyclophotocoagulation relieved areas of chafing and resolved symptoms. In-the-bag square-edged haptics of single-piece acrylic IOLs are a potential source of iridociliary chafing in certain situations. The mechanisms observed here should be considered to promptly diagnose and treat UGH.
