PURPOSE To compare a new insertion method using an EndoGlide (Angiotech/Network Medical Products) with the standard Busin glide (Moria USA) assisted insertion of the posterior lamellar corneal graft in Descemet stripping endothelial keratoplasty (DSEK). DESIGN Prospective, consecutive, comparative, nonrandomized study. METHODS Surgery was performed between October 2008 and October 2010 in 5...
DEEP ANTERIOR LAMELLAR KERATOPLASTY: A NEW MANUAL TECHNIQUE Rama et al report visual outcomes in 288 eyes undergoing deep anterior lamellar keratoplasty with a new manual dissection technique. A deep corneal incision was obtained with a calibrated diamond knife to reach a pre-Descemet plane. At the 2-year postoperative follow-up, the mean logarithm of the minimum angle of resolution best specta...
IMPORTANCE Surgeons starting to perform Descemet membrane endothelial keratoplasty (DMEK) should be informed about the learning curve and experience of others. OBJECTIVE To document the clinical outcome of standardized "no-touch" DMEK and its complications during the learning curves of experienced surgeons. DESIGN, SETTING, AND PARTICIPANTS Retrospective multicenter study. A total of 431 ey...
PURPOSE Descemet stripping automated endothelial keratoplasty (DSAEK) can be performed with donor tissue prepared with a microkeratome either by the surgeon at the time of surgery or by a technician in the eye bank days before surgery. Are the complications and endothelial survival affected by donor preparation by a surgeon vs a technician? METHODS A single surgeon at a referral practice perf...
PURPOSE To assess the clinical outcomes of DMEK in the first series of 120 eyes operated for the treatment of Fuchs endothelial dystrophy in terms of visual acuity and endothelial cell density. METHODS The first 120 consecutive eyes that underwent DMEK (i.e. transplantation of an isolated donor Descemet membrane with its endothelium) were evaluated. In all eyes, the best corrected visual acui...
PURPOSE To report early, specific changes in donor endothelial cell morphology as a predictor of an upcoming allograft rejection after Descemet membrane endothelial keratoplasty (DMEK). DESIGN Retrospective, observational case series. METHODS Out of a cohort of 500 eyes that underwent DMEK at a tertiary referral center, 7 eyes developed typical clinical signs of an allograft rejection. Spec...
PURPOSE To describe the preparation and thickness profiles of endothelial keratoplasty lenticules harvested from eyes with previous photorefractive keratectomy (PRK). METHODS Donor whole eyes that underwent PRK were subjected to microkeratome-assisted dissection for Descemet stripping automated endothelial keratoplasty. Specular microscopy and Visante optical coherence tomography were perform...
To the Editor: Descemet detachment in cataract surgery can compromise visual results and implicate the need for more surgical procedures.1 Since 2009, when femtosecond laserassisted cataract surgery (FLACS) was first introduced, only one case of Descemet detachment has been reported in a study assessing intraoperative complication rates, and it is not clear whether the detachment was caused by ...
