Recurrent suprachoroidal dislocation of an anterior chamber intraocular lens.

We present a patient with a history of posterior chamber intraocular lens (PC IOL) implantation and trabeculotomy 9 years previously who recently had IOL exchange for an angle-based anterior chamber IOL. Twenty-four hours after the exchange, he was referred to us with hypotony and "loss" of the IOL. Ultrasound revealed a rigid choroidal detachment and echoes suggestive of a suprachoroidally dislocated IOL. Anterior vitrectomy and resuturing of the incision were performed. Subsequently, the IOL repeatedly migrated in and out of the suprachoroidal space, allowing atraumatic removal. Angle-based IOL implementation should be avoided in eyes with a history of trabeculotomy or cyclodialysis.
