Complications of Scleral-Fixated Intraocular Lenses.

INTRODUCTION

Understanding the evolution of complications after scleral-fixated lens placement demonstrates advantageous surgical techniques and suitable candidates.

MATERIALS/METHODS: A literature search in PubMed for several terms, including "scleral intraocular lens complication," yielded 17 relevant articles.

RESULTS

Reviewing complication trends over time, lens tilt and suture erosion have decreased, cystoid macular edema has increased, and retinal detachment has remained the same after scleral-fixated lens placement. The successful reduction in complications are attributed to several alterations in technique, including positioning sclerotomy sites 180 degrees apart and using scleral flaps or pockets to bury sutures. Possible reduction in retinal risks have been proposed by performing an anterior vitrectomy prior to lens placement in certain settings.

DISCUSSION

Complications after scleral-fixated lens placement should assist patient selection. Elderly patients with a history of hypertension should be counseled regarding risk of suprachoroidal hemorrhage, while young patients and postocular trauma patients should be considered for concurrent anterior vitrectomy.
