purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

A 39-year-old woman presented to our hospital with a history of photorefractive keratectomy (PRK), performed two weeks prior; slit-lamp examination revealed diffuse conjunctival congestion, corneal ulcer and stromal infiltration. After 5 days of antifungal and antibacteric treatment, the infiltrate progressively increased so that a therapeutic penetrating keratoplasty was necessary. The microbi...

Introduction Urrets-Zavalia syndrome is an uncommon complication of the deep anterior lamellar keratoplasty in keratoconus. The manifestations of this syndrome are an irreversible mydriasis, iris atrophy and secondary glaucoma. Case report Deep anterior lamellar keratoplasty was done for keratoconus with a presumably healed corneal hydrops in a 21-year-old Caucasian man. The graft remained cl...

AIM To analyse ocular biomechanical properties, central corneal thickness (CCT) and intraocular pressure (IOP) in post-keratoplasty eyes, as compared to normal subjects, with a new Scheimpflug-based technology. Moreover, biomechanical data were correlated with the size and age of the donor and recipient corneas. METHODS Measurements were conducted on 46 eyes of 46 healthy patients without any...

Descemet stripping endothelial keratoplasty (DSEK) is an alternative to penetrating keratoplasty in the surgical management of endothelial disorders. The major advantage of DSEK over penetrating keratoplasty is that the integrity of the anterior cornea is largely maintained in DSEK. Hence, patients undergoing DSEK have a lower risk of complications such as suprachoroidal hemorrhage and postoper...

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...

OBJECTIVES Study aims to evaluate the indications and surgical techniques for corneal transplantation and to report changes in trends for preferred keratoplasty surgical techniques. METHODS Clinical records of 815 consecutive corneal transplantations between January 1, 2004 and December 31, 2014 in Haydarpasa Numune Training and Research Hospital Eye Clinic were analyzed and classified into s...

The accuracy of intraocular pressure measurement with the minified Goldmann applanation tonometer, the pneumatonometer, and the Tono-Pen tonometer were compared in post-mortem human eyes which had undergone penetrating keratoplasty. Enucleated post-mortem human eyes underwent same sized (7.75 mm) or 0.5 mm oversized (8.25 mm) autologous penetrating keratoplasty. Intraocular pressure was then se...
