Modified dagger-tip Sheets glide to facilitate 2-point fixation across the anterior chamber in aniridic aphakic eyes.

Abstract

Presented is a modified technique for removing a failed endothelial allograft in an aniridic aphakic eye that reduces the risk of posterior dislocation. This technique involves the creation of an artificial iris plane using a Sheets glide by trimming it into the shape of a dagger so that it can be pulled through the anterior chamber and fixated by both its passage through a paracentesis incision and the main incision. The Sheets glide then acts as a physical barrier, or scaffold, to allow safe removal of the failed endothelial allograft and subsequent repeat endothelial keratoplasty while avoiding posterior dislocation of the tissue into the vitreous cavity.
