purpose: to evaluate bacterial and fungal contamination of donor corneas before and after decontamination at eye bank of i.r. of iran based on cultures. methods: this descriptive study was performed on 131 donor eyes (whole globe or cut cornea) used for corneal transplantation at labbafinejad hospital during a 6-month period. microbiologic culture was performed at three stages: before enucleati...

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 adverse effects of intravitreal injection of sterile chloramphenicol eye drops on corneal endothelial cells of donated corneas. methods: 100 donor corneas were enrolled in the study. one eye of each donor underwent intravitreal injection of sterile chloramphenicol eye drops following vitreous tap and the fellow eyes were served as controls. after corneo-scleral excision...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...

purpose: to describe a new noninvasive method to assure correct orientation of donor lenticules in descemet stripping automated endothelial keratoplasty (dsaek) surgery. methods: dsaek surgery was performed in three eyes with the diagnosis of pseudophakic bullous keratopathy (pbk). for the laboratory part of the study, two whole globes and two precut corneoscleral buttons were used. the donor l...

purpose: to report the possible transmission of zygomycetes infection by a corneal graft harvested from a donor with signs of trauma to the orbital region to a keratoconic patient who underwent deep anterior lamellar keratoplasty (dalk). case report: a 19-year-old keratoconic man underwent dalk in the right eye. the corneal graft was harvested from a donor with signs of orbital trauma. on posto...

purpose: to report a case of pseudoexfoliation syndrome in young keratoconus patient following penetrating keratoplasty. case report: a 37 year old man who underwent penetrating keratoplasty 13 years ago in his left eye due to keratoconus developed pseudoexfoliation (pex) syndrome in the operated eye. apart from pex material deposition on the crystalline lens ophthalmic exam was within normal l...

Descemet's Membrane Endothelial Keratoplasty (DMEK) is a form of corneal transplantation in which only a single cell layer, the corneal endothelium, along with its basement membrane (Descemet's membrane) is introduced onto the recipient's posterior stroma(3). Unlike Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK), where additional donor stroma is introduced, no unnatural stroma-...

PURPOSE To evaluate the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (PK) for keratoconus. METHODS This retrospective interventional case series included 252 keratoconic eyes which underwent PK. Donor data included age and sex, cause of death, death-to-preservation time, preservation-to-surgery time, epithelial and stromal s...
