Surgical treatment of dislocated iris-plane intraocular lenses.

This report describes a patient with a Binkhorst four-loop intraocular lens dislocated in the vitreous. The implant was repositioned by means of a combination of the Barraquer-Chowdhury needle-fixation method with a McCannel suture. The pupil was maximally dilated, and the patient was placed in the prone position. When the implant drifted into the anterior chamber, it was anchored with a 25-gauge spinal needle through the limbus. It was then refixated to the iris with a 10-0 prolene suture.
