Purpose: The purpose of this study is to analyze the course of corneal densitometry (CD), endothelial cell density (ECD), best-corrected visual acuity (BCVA), and central corneal thickness (CCT) 5 years after uneventful Descemet membrane endothelial keratoplasty (DMEK).
Methods: Sixty uneventful cases (51 patients) with a minimum follow-up of 5 years were included. CD of various corneal layers (anterior, central, posterior, and total layer) and zones (0-2 mm, 2-6 mm, and 6-10 mm) were measured with Scheimpflug tomography.
Purpose: To report the outcomes of secondary Descemet Membrane Endothelial Keratoplasty (DMEK) performed for failed primary DMEK.
Methods: The medical records of all patients undergoing secondary DMEK due to failure of primary DMEK were reviewed. Reasons for failure were sought and best-corrected visual acuity (BCVA), endothelial cell density (ECD) and complications of secondary DMEK were evaluated.
Purpose: To evaluate the effect of a single rebubbling procedure after Descemet membrane endothelial keratoplasty (DMEK) on corneal backscatter and endothelial cell loss (ECL).
Methods: Medical records of 130 consecutive DMEK cases (118 patients) were reviewed and 3 groups were formed: group 1 (n = 32), consisting of DMEK cases followed by 1 rebubbling; group 2a (n = 55), including uneventful DMEK cases with complete graft attachment; and group 2b (n = 25), including uneventful DMEK cases with minor peripheral detachment, not requiring rebubbling. Scheimpflug corneal densitometry (CD) of the central (0-2 mm), paracentral (2-6 mm), and mid-peripheral (6-10 mm) zones, endothelial cell density, central corneal thickness, and corneal volume were measured preoperatively and at 3, 6, 12, and 24 months.
Purpose: To compare the course of Scheimpflug corneal densitometry (CD) after Descemet membrane endothelial keratoplasty (DMEK) versus Descemet stripping automated endothelial keratoplasty (DSAEK).
Methods: Fifty-four DMEK and 25 DSAEK cases without previous corneal surgery, complicated intraoperative or postoperative course, or vision-limiting ocular comorbidities were included. Pseudophakic eyes of age-matched subjects were recruited as controls (n = 20).
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. The rebubbling rate, complications, best-corrected distance visual acuity (BCVA), manifest refraction, and endothelial cell density were analyzed before and at 1 week, 1, 3, 6, 12, 24, and 36 months after surgery.
Purpose: To evaluate the learning curve of standardized "no-touch" Descemet membrane endothelial keratoplasty (DMEK) of a single surgeon in a clinic without an in-house eye bank facility.
Methods: For 25 eyes of 22 patients, Descemet graft preparation and DMEK surgery were performed according to the protocols of the Netherlands Institute for Innovative Ocular Surgery with minor modifications. Best spectacle-corrected visual acuity, subjective refraction, Scheimpflug tomography, and endothelial cell density of the donor tissue were documented before and at 1, 3, and 6 months after the surgery; intraoperative and postoperative complications were recorded.
