Dislocation of intraocular lens

Abstract

BACKGROUND: Cataract surgery with implantation of an artificial intraocular lens (IOL) in the lens capsule ('in-the-bag') is one of the world's most common surgeries. After many years, this IOL capsule complex may dislocate. This condition, called late in-the-bag IOL dislocation, has an estimated incidence of 0.5-1 %, with increasing frequency. CASE PRESENTATION: A man in his late seventies presented with monocular decreased vision and high intraocular pressure. Pupil dilation revealed the diagnosis of late in-the-bag IOL dislocation. Surgery was performed with repositioning of the dislocated complex by scleral suturing. The patient's visual acuity normalised after surgery. INTERPRETATION: Late in-the-bag IOL dislocation is no longer a rare condition. It requires surgery, which may be performed either as repositioning of the dislocated complex or by exchanging it for a new IOL. Both operation methods give a good visual outcome.
