Human corneal endothelium has long been thought to be a non-mitotic cell layer with no endogenous reparative potential. Pathologies that damage endothelial function result in corneal decompensation and, if untreated, blindness. The mainstay of treatment involves partial or complete corneal replacement, amounting to 40% of all corneal transplants performed worldwide. We summarize the case reports describing complications post-operatively in the form of (sub)total graft detachment and those resulting in post-operative bare stroma...

PURPOSE: To report the first case of Candida donor to host transmission following descemet membrane endothelial keratoplasty (DMEK). METHODS: A retrospective case report. RESULTS: A patient underwent uneventful DMEK. Following surgery the donor rim was culture positive for Candida. The patient developed fungal endophthalmitis that was treated medically with multiple injections of voriconazole and amphotericin. Medical treatment was unable to clear the infection and removal of the donor material was required...

Descemet membrane endothelial keratoplasty (DMEK) has evolved into a routine surgical procedure for posterior lamellar keratoplasty. After its introduction more than 10 years ago, several modifications in grafting technique and postoperative treatment regimen helped to improve its safety and reproducibility. Although DMEK offers faster and better improvements in visual acuity, as well as less graft rejections when compared to Descemet's stripping (automated) endothelial keratoplasty (DS[A]EK), difficulties when implementing this technique hamper the widespread use in many areas...

PURPOSE: To evaluate whether donor and/or recipient diabetes status affects the outcomes of Descemet membrane endothelial keratoplasty (DMEK). METHODS: A consecutive, single-center DMEK case series was reviewed. The outcome measures were success of surgeon tissue preparation, air reinjection rate, Kaplan-Meier 4-year graft replacement/failure rate for any reason, and endothelial cell loss. RESULTS: The donor had a history of diabetes in 504 of 1791 cases (28%) and the recipient in 14%...

PURPOSE: To report a case of coexistent Fuchs endothelial corneal dystrophy (FECD) and keratoconus (KCN) in which there was normalization of corneal topography after Descemet membrane endothelial keratoplasty (DMEK). METHODS: Retrospective medical record review. RESULTS: Preoperative findings revealed a best-corrected visual acuity of 20/40 with -1.00 - 2.50 × 147, topographic maximum keratometry of 50.8 D with inferior steeping, and confluent guttae in the left eye...

PURPOSE: To compare the rebubbling rate and clinical outcomes of Descemet membrane endothelial keratoplasty (DMEK) with 5% sulfur hexafluoride (SF6) gas versus 100% air as a tamponade for graft attachment. METHODS: Retrospective, comparative, interventional case series including 368 consecutive pseudophakic eyes with Fuchs endothelial dystrophy or pseudophakic bullous keratopathy that underwent DMEK in a tertiary referral center between October 2010 and August 2015 using either air (group 1, 191 eyes) or 5% SF6 (group 2, 177 eyes) as a tamponade...

Descemet Membrane Endothelial Keratoplasty (DMEK) is a selective replacement of dysfunctional endothelium with healthy donor Descemet's membrane and endothelium. Although the donor preparation and surgical methods still remain a challenge, DMEK is gaining popularity in terms of early rehabilitation and visual outcomes. New and improved donor preparation techniques like pre-stripped DMEK tissues are taken up rapidly due to less manipulation that is required in the surgical theatre. Donor graft delivery in the recipient eye has also been improved due to new products like pre-stripped and pre-loaded membranes...

Objective: To evaluate the clinical outcomes of Descemet's membrane endothelial keratoplasty (DMEK) for treatment of patients with corneal endothelial decompensation in China. Methods: Interventional case series. Ten patients (10 eyes) with the diagnosis of corneal endothelial decompensation received DMEK during July 2016 and September 2016 in Zhongshan Ophthalmic Center. Descemet's membrane of the donor tissue was carefully stripped from the underlying stroma manually and cut with a 7.75- or 8.0-mm-diameter donor punch...

Endothelial keratoplasty (EK) has revolutionized corneal transplant surgery by providing rapid visual recovery and improved visual outcomes. In parts of the world with Fuchs endothelial dystrophy, many patients may present with both cataracts and corneal degeneration requiring surgery. Other forms of endothelial decompensation may also present with cataracts. The staging or combination of transplant surgery and cataract surgery depend on both the abilities of the surgeon and the surgical techniques being considered...

PURPOSE: To present the results of 15 cases in which a modified technique of Descemet membrane endothelial keratoplasty (DMEK) with vent incisions was used to assist unfolding of tight peripheral inward folds. METHODS: This is a retrospective case series of 15 consecutive eyes that underwent a modified vent incision technique for DMEK. Six oblique, small-size (1 mm) vent incisions parallel to the limbus and 3.5 mm from the center were performed after descemetorhexis...

Endothelial keratoplasty (EK) has revolutionized treatment of corneal endothelial dysfunction. Compared with penetrating keratoplasty (PK), EK provides faster and more reliable visual rehabilitation while maintaining the eye's structural integrity. The number of EK procedures is growing annually and surpassed PK in the United States in 2012. The most widely used iteration, Descemet stripping endothelial keratoplasty (DSEK), implants healthy donor endothelium, Descemet membrane, and posterior stroma. Descemet membrane endothelial keratoplasty (DMEK) eliminates the donor stromal layer...

Purpose: Develop a silk fibroin (SF)-based artificial endothelial graft for its use in a rabbit Descemet membrane endothelial keratoplasty (DMEK). Methods: Human and rabbit artificial corneal endothelial grafts were developed through the culture of human and rabbit corneal endothelial cells (CECs) on SF films. Rabbit artificial SF endothelial grafts were transplanted in a DMEK surgery into a rabbit in vivo model. Results: SF artificial endothelial grafts showed the characteristic endothelial markers: zonula occludens (ZO-1) and Na+/K+ ATPase...

Vital staining of the endothelial graft is essential during Descemet's membrane endothelial keratoplasty (DMEK) to ensure surgical success. DMEK surgeons worldwide commonly use trypan blue (TB) to this end. However, TB may exert toxic effects on both the cornea and retina. Recently, Brilliant Blue G (BBG) has become recognized as an alternative stain for use during vitreoretinal surgery; BBG is associated with lower levels of toxicity. We retrospectively analyzed the utility of BBG staining during DMEK. We used 0...

Purpose. To evaluate changes in anterior, posterior, and total corneal astigmatism in patients after Descemet membrane endothelial keratoplasty (DMEK). Methods. We retrospectively included 29 eyes of 23 patients (age 67.6 ± 9.8 years, 13 female, 10 male) after DMEK surgery. The magnitude and axis orientation of anterior, posterior, and total corneal astigmatism before and after DMEK were determined using a rotating Scheimpflug system (Pentacam HR, Oculus). Results. The magnitude of anterior, posterior, and total corneal astigmatism in the central cornea did not change significantly after surgery...

INTRODUCTION: Use of Descemet Membrane Endothelial Keratoplasty (DMEK) has been limited because of problems with donor preparation, i.e. tearing of the Descemet membrane and difficulties in unfolding the Endothelium-Descemet-Membrane-Layer (EDML) in the anterior chamber (AC). The purpose of this work was to describe a novel approach to teaching anatomy-based donor and recipient preparation in a DMEK-Wetlab. MATERIAL AND METHODS: We teach successful mono-manual donor preparation of human corneas in organ culture not suitable for transplantation, including peripheral markers for orientation...
