Cataract surgery in the setting of trauma

Abstract

Purpose: To review the changes in the surgical techniques used for cataract removal in the setting of trauma and their postoperative outcome.

Recent findings: Primary cataract removal with intraocular lens (IOL) implantation is the commonly followed procedure for penetrating injuries with cataract. IOL implantation has evolved through various techniques namely 'in the bag', 'in the sulcus', epilenticular implantation, anterior chamber IOL, scleral fixated IOL and recently glued IOL.

Summary: Certain lacerating injuries of the anterior segment are particularly amenable to cataract extraction and IOL implantation at the time of primary laceration repair. This approach obviates additional operative and anesthetic risks, while affording timelier visual rehabilitation. Secondary lens removal may also be indicated in cases of severe corneal injury and marked edema, which may interfere with intraocular visualization.
