ABSTRACT Objective: To describe a new surgical maneuver to position the graft in a Descemet Stripping with Automated Endothelial Keratoplasty (DSAEK) surgery. Methods: Case series. Results: This technique allows a correct repositioning of the graft in a minimally invasive way. Conclusion: This new su...

ABSTRACT Purpose: This study aimed to investigate the effect of using a viscoelastic substance in Descemet's membrane rupture in "double bubble" deep anterior lamellar keratoplasty. Methods: The medical records and videos of surgeries of 40 patients who underwent surgery between January 2014 and July 2...
ABSTRACT Description of a patient with Fuchs endothelial dystrophy submitted to a corneal transplant, performed by Descemet membrane endothelial keratoplasty, which evolved with sudden, paroxysmal pain in the frontotemporal region, postoperatively. Due to the ophthalmologic picture of the patient, the at...

ABSTRACT Purpose: The length of Descemet's membrane and donor graft sizes in deep anterior lamellar keratoplasty do not match in very steep corneas, which can lead to Descemet's membrane folds. The aim of this study is to establish a theoretical model for graft size calculations for deep anterior lamell...
ABSTRACT Here, we describe the result of a Descemet's membrane endothelial keratoplasty for acute corneal hydrops in a 45-year-old female with keratoconus, who presented with severe visual loss in her OS. The patient's best-corrected visual acuity was 20/80 in the right eye and hand motion in the OS. Sli...
ABSTRACT Purpose: We report a simplified Descemet's membrane endothelial keratoplasty (DMEK) technique that involves safe and effective preparation and introduction, correct orientation, and easy unfolding of the donor graft inside the recipient anterior chamber. Methods: In this retrospective study, w...

ABSTRACT We report intraoperative finding of Granular Corneal Dystrophy Type-1 (GCD1) deposits after stromal pneumodissection in deep anterior lamellar keratoplasty (DALK) in a 61-year-old female. Pneumodissection was performed from the center to the periphery of the cornea, characterizing a big bubble t...

Abstract We report an unusual case of a 65-year old patient that developed localized bilateral Descemet membrane detachment during non-simultaneous femtosecond laser-assisted cataract surgery (FLACS). The detachment occurred when the laser was performing the secondary incision. In the operating room, the...
ABSTRACT Purpose: The optical quality of the interface after deep anterior lamellar keratoplasty (DALK) using the big-bubble technique has been shown to be excellent, leading to results comparable to penetrating keratoplasty. However, there is little in the literature with respect to the controversy sur...

ABSTRACT Purpose: To compare the effect of 20% sulfur hexafluoride (SF6) with that of air on graft detachment rates for intraocular tamponade in Descemet membrane endothelial keratoplasty (DMEK). Methods: Forty-two eyes of patients who underwent DMEK by a single surgeon (A.S.J.) at Wilmer Eye Institute...
