Purpose Iridocorneal endothelial (ICE) syndrome is a progressive anterior segment disorder that can be tricky to treat. Keratoplasty commonly used treat corneal edema in ICE syndrome. However, glaucoma an important risk factor affecting graft survival. To address this question, we designed retrospective cohort study evaluate the effect of Spokewise Iridotomy (SI) on Descemet Stripping Automated...
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...
Penetrating keratoplasty (PKP) has a long track record of high success rates compared to other tissue and organ transplantations. Despite the immunologic privilege of the cornea, the issue of immunological rejection cannot be overlooked and endothelial rejection is observed in up to 20% of eyes undergoing PKP. 1 Repeat keratoplasties after rejection are increasingly more prone to rejection and ...
Considerable interest has been generated for the development of suitable corneal endothelial graft alternatives through cell-tissue engineering, which can potentially alleviate the shortage of corneal transplant material. The advent of less invasive suture-less key-hole surgery options such as Descemet's Stripping Endothelial Keratoplasty (DSEK) and Descemet's Membrane Endothelial Keratoplasty ...
PURPOSE To report a case of progressive fibrotic contraction of the posterior lamellar graft after initially successful Descemet's stripping automated endothelial keratoplasty (DSAEK). METHODS Retrospective report of clinical data and histopathological analysis of excised corneal tissue. RESULTS A 63-year-old woman underwent uncomplicated DSAEK in her left eye due to endothelial dystrophy. ...
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 Few complications have been reported for deep lamellar endothelial keratoplasty (DLEK). Endothelial graft failure has rarely been disclosed as a complication. Although the histopathologic and ultrastructural analysis of a failed DLEK graft has been previously described, we are not aware of any reports of these features in a case of traumatic endothelial graft failure. METHODS We repor...
