PURPOSE To describe the utility of a new intraoperative optical coherence tomographer (OCT) to evaluate endothelio-Descemet graft orientation during Descemet membrane endothelial keratoplasty (DMEK) procedures. METHODS Prospective, observational, and single-center pilot case series including 14 eyes of 14 patients consecutively scheduled for DMEK surgery. After injecting the graft into the an...

Penetrating corneal transplant (PKP) surgery has been performed for centuries as the procedure of choice to restore vision in cases of advanced corneal disease. However, the last two decades have seen the introduction of lamellar corneal surgery (deep anterior lamellar keratoplasty, DALK; Descemet stripping-automated endothelial keratoplasty, DSAEK; and Descemet membrane endothelial keratoplast...

PURPOSE The demands for precut lamellar grafts for Descemet stripping automated endothelial keratoplasty rose in our eye bank from 74 in 2007 to 408 in 2010. To meet this expanding requirement, we explored the possibility to preserve these preparations in organ culture. METHODS Organ cultured corneas, stored in a medium containing 6% dextran, were mounted on a Moria artificial anterior chambe...

Deep anterior lamellar keratoplasty (DALK) is a surgical technique for cornea replacement, which the healthy host corneal endothelium is preserved. Keratoconus patients are those who benefit most from a successful DALK procedure, once the endothelium of these patients is usually normal and should therefore be maintained. Several studies comparing visual outcomes between penetrating keratoplasty...
