Postoperative tilting of a well-enclaved retropupillary iris claw intraocular lens: A rare complication

Abstract

Here, we report a rare complication of the retropupillary iris claw intraocular lens (IOL) which in recent times has emerged as a good option for implantation in cases with inadequate capsular support following cataract surgery. Three weeks after undergoing iris claw IOL implantation, our patient presented with sudden decrease in visual acuity. On examination, we found the iris claw IOL to be tilted by 90° and lying perpendicular to the pupillary plane with the haptics still enclaved. Resurgery was done to reposition the IOL. The tremulousness of the iris causing an anterior movement of the iris diaphragm and IOL, aided by prolapse of vitreous could have caused the tilt.
