OBJECTIVES To investigate visual outcome and postoperative complications in patients undergoing Descemet membrane endothelial keratoplasty with graft failure after penetrating keratoplasty. MATERIALS AND METHODS A retrospective analysis was performed with 5 patients who underwent Descemet membrane endothelial keratoplasty after failed penetrating keratoplasty. Intraoperative and postoperative...

PURPOSE To investigate the incidence, mechanisms, characteristics, and visual outcomes of traumatic wound dehiscence following keratoplasty. METHODS Medical records of 32 consecutive patients with traumatic globe rupture following keratoplasty who had been treated at our center from 2001 to 2009 were retrospectively reviewed. RESULTS The study population consisted of 32 eyes of 32 patients ...

BACKGROUND High-risk keratoplasties are usually performed after an uninflamed and quiescent interval in corneas with partly regressed blood and lymphatic vessels. We analysed whether the inhibition of post-keratoplasty revascularisation in mice with partly regressed corneal vessels ("intermediate-risk") improves graft survival. METHODS Three interrupted stromal sutures (11-0) in corneas of Ba...

To present 2 cases with long-term relapse-free intervals only after limbo-keratoplasty but not after conventional penetrating keratoplasty in granular dystrophy.Retrospective review of the patient charts and photographs taken during long-term follow-up of 2 cases with granular dystrophy, in which 1 eye received penetrating keratoplasty and the fellow eye received penetrating limbo-keratoplasty....

BACKGROUND In this paper, we report our experience of the clinical features of single and repeated globe rupture after penetrating keratoplasty. METHODS We undertook a retrospective analysis of single and repeated globe ruptures following keratoplasty in eight eyes from seven consecutive patients referred to Kanazawa University Hospital over a 10-year period from January 2002 to March 2012. W...

Corneal transplantation has evolved rapidly over the past decade, as surgeons strive to refine selective tissue transplantation to treat diseases that affect specific layers of the cornea. The first successful penetrating corneal transplantation was performed by Eduard Zirm in 1905. In 1931, Ramon Castroviejo, MD, while a fellow at Mayo Clinic, refined the techniques for penetrating keratoplast...

PURPOSE The purpose of this study was to evaluate sutureless keratoplasty using a chemically-defined bioadhesive (CDB) made from food or medical additives. METHODS Sutureless automated lamellar therapeutic keratoplasty (ALTK) using a CDB was performed on three rabbit eyes. Allogenic lamellar graft was transplanted onto the recipient bed using either suture fixation or a sutureless technique u...
