AIM To study the demographic, clinical, and microbiological profile and the risk factors for graft infection following penetrating keratoplasty. METHODS 50 eyes of 50 consecutive patients with graft infection after an optical penetrating keratoplasty were included as cases; 50 eyes of 50 patients with no graft infection were included as controls. The main variables evaluated in this study inc...

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: to compare clinical outcomes following penetrating keratoplasty (pk) versus deep anterior lamellar keratoplasty (dalk) for keratoconic patients with vernal keratoconjunctivitis (vkc). methods: in this retrospective comparative study, the records of 69 keratoconic eyes with vkc that underwent pk (n=43, group 1) or dalk (n=26, group 2) were compiled. postoperative best-corrected visual a...

BACKGROUND Indications for corneal transplantation in developed and developing nations differ according to the different spectrum of corneal disease in each country. OBJECTIVE The purpose of this study is to analyze the changing indications and surgical techniques for corneal transplantation over the past 20 years at a tertiary referral center in Turkey. METHODS We retrospectively reviewed ...

Corneal transplantation or keratoplasty has developed rapidly in the past 10 years. Penetrating keratoplasty, a procedure consisting of full-thickness replacement of the cornea, has been the dominant procedure for more than half a century, and successfully caters to most causes of corneal blindness. The adoption by specialist surgeons of newer forms of lamellar transplantation surgery, which se...

INTRODUCTION We describe a case of refractory Pasteurella Canis keratitis that initially failed antimicrobial treatment but was successfully treated with a conjunctival flap followed by a penetrating keratoplasty. CASE DISCUSSION A 70-year-old male had persistent corneal edema related to previous herpes zoster keratouveitis with visual acuity of 20/400. An endothelial keratoplasty was perform...

To measure the corneal thickness and the depth of the precorneal tear film of contact lens wearers with keratoconus or keratoplasty and to reconfirm the identification and classification of the keratoconus with optical coherence tomography (OCT). The cornea and precorneal tear film of 123 eyes with keratoconus, of 39 eyes after keratoplasty and 8 eyes after LASIK were examined with an OCT (Zeis...
