Simultaneous correction of aniridia and aphakia

摘要

Li et al.'s technique for black diaphragm iris implantation and the accompanying editorial raise important issues about the management of traumatic aniridia. Although the article does not mention the make or model of the intraocular lens (IOL) used, from the figures and accompanying video, it appears to be the Morcher type 67B or type 68 (Morcher GmBH). These IOLs consist of an opaque black polymethyl methacrylate (PMMA) diaphragm with a central transparent 3.0 mm optic and a 4.5 mm optic, respectively.The black PMMA from which these particular iris device-IOL complexes are made is a rather stiff material. While we have no objection to placing sutures in front of the IOL for augmented stabilization, we think the proposition that the IOL flexing forward is the origin of increased risk for corneal decompensation in such cases is speculative without data to support it.
