title: Traumatic pupillary capture of the haptic of an angle-supported phakic intraocular lens.
abstract: A 27-year-old woman had implantation of an angle-supported phakic intraocular lens (pIOL) for myopia in the left eye in 2003. Moderate iris atrophy and pupil ovalization were noted in 2005. In 2006, the eye was hit by a plastic bullet shot from a toy gun. The pupil became distorted as the inferior haptic engaged the pupil edge. Visual acuity was not affected. Surgical repositioning was uneventful, yielding a round pupil with no damage to the iris sphincter or the lens. The endothelium was not affected by the trauma or surgery. Previous iris atrophy may have facilitated pupillary capture because of reduced iris elasticity and pupil ovalization by the haptic. Blunt trauma can dislocate angle-supported pIOLs. Implantation of these IOLs should be discouraged in patients who perform activities that put them at risk for eye trauma.
