PURPOSE To describe the preparation and thickness profiles of endothelial keratoplasty lenticules harvested from eyes with previous photorefractive keratectomy (PRK). METHODS Donor whole eyes that underwent PRK were subjected to microkeratome-assisted dissection for Descemet stripping automated endothelial keratoplasty. Specular microscopy and Visante optical coherence tomography were perform...

PURPOSE Many corneal surgeons are making the transition from penetrating keratoplasty to endothelial keratoplasty techniques such as Descemet's stripping endothelial keratoplasty and Descemet's stripping automated endothelial keratoplasty in the routine treatment of corneal endothelial failure. Donor dislocation is the commonest complication of these newer techniques. We set out to determine wh...

purpose: to evaluate endothelial cell density (ecd) and morphology of clear corneal grafts after descemet stripping automated endothelial keratoplasty (dsaek) and to determine the factors that influence graft ecd postoperatively. methods: seventy-seven eyes (38 right eyes) of 64 patients (34 female subjects) who underwent dsaek for fuchs’ endothelial dystrophy (n=38) or pseudophakic bullous ker...

Corneal endothelial transplantation or endothelial keratoplasty has become the preferred choice of transplantation for patients with corneal blindness due to endothelial dysfunction. Currently, there is a worldwide shortage of transplantable tissue, and demand is expected to increase further with aging populations. Tissue-engineered alternatives are being developed, and are likely to be availab...

PURPOSE To report the indications and techniques of corneal transplantation at a tertiary referral center in Tehran over a 3-year period. METHODS Records of patients who had undergone any kind of corneal transplantation at Labbafinejad Medical Center, Tehran, Iran from March 2004 to March 2007 were reviewed to determine the indications and types of corneal transplantation. RESULTS During th...

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...

Descemet-stripping automated endothelial keratoplasty (DSAEK) has become the procedure of choice to treat corneal endothelial dysfunction. The technique involves replacing the diseased host endothelium with a graft consisting of a thin layer of posterior stroma, Descemet membrane, and endothelium. In comparison to penetrating keratoplasty (PK), DSAEK confers quicker visual and structural recove...
