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...

Purpose: To evaluate the long-term outcomes of medically or surgically treated patients with atopic keratoconjunctivitis (AKC). Methods: Charts of 16 patients with AKC (32 eyes) observed between 1996 and 2013 were reviewed retrospectively. Outcome measures included demographic features, follow-up duration, and biomicroscopic findings at the first and most recent visits. The corrected distance...

Purpose. To compare the higher-order aberrations (HOAs) due to the anterior and posterior corneal surfaces in patients that underwent either Descemet-stripping-automated-endothelial-keratoplasty (DSAEK) or penetrating keratoplasty (PK) for endothelial dysfunction and age-matched controls. Methods. This retrospective, observational, case series included 28 patients after PK, 30 patients after DS...

A 70-year-old male patient had previously underwent trabeculectomy with mitomycin-C in the left eye because of high intraocular pressure. The was needled 5 fluorouracil 2 weeks after operation. Seven days needling procedure, complained pain, redness, stinging, and decreased vision eye. Abiomicroscopic examination performed. corneoscleral infiltration area, including bleb detected at 12 clock po...
