Can be a complication of anterior chamber IOLs, especially in eyes with oversized angle-supported AC IOLs or secondary to iris tuck.
Usually asymptomatic, but in certain cases may cause significant symptoms of night glare, halos or diplopia.
The axis of the pupillary distortion usually coincides with the major axis of the AC IOL
Chronic haptic loop compression against the iris root could induce ischemic and inflammatory changes as well as sector iris atrophy.
Correct positioning of the haptics and precise measurement of limbus-to-limbus diameter are essential for an optimal surgical result.
Topical steroids may be appropriate for inflammation reaction.
IOL explantation may be required in cases with severe symptoms and compromised anterior chamber structures that cause uveitis, glaucoma, hyphema (UGH) syndrome, corneal endothelial loss or pseudophakic bullous keratopathy.
