Peripheral iridectomy for atraumatic haptic externalization in large eyes having anterior sclerotomy for glued intraocular lens

摘要

We describe a simple technique of vitrector-assisted peripheral iridectomy performed along the base of the scleral flap and beneath a corneal mark at the 180-degree axis for atraumatic haptic externalization in large eyes having glued intrascleral haptic fixation of an intraocular lens (IOL). Anterior sclerotomy is often performed in large eyes, which shifts the IOL plane anteriorly, often leading to peripheral iris damage during the anterior sclerotomy or haptic externalization. The vitrector-assisted peripheral iridectomy helps to prevent iatrogenic iris tissue damage during the surgical procedure.
