The aim of this study was to investigate the effects of using LC-DCP versus fresh corneas on graft transparency after penetrating keratoplasty. The observation group (25 eyes of 25 patients) was performed penetrating keratoplasty with LT-DCP cornea, while the control group (23 eyes of 23 patients) was performed penetrating keratoplasty with fresh cornea form human corpses. The follow-up was 3 t...

To present 2 cases with long-term relapse-free intervals only after limbo-keratoplasty but not after conventional penetrating keratoplasty in granular dystrophy.Retrospective review of the patient charts and photographs taken during long-term follow-up of 2 cases with granular dystrophy, in which 1 eye received penetrating keratoplasty and the fellow eye received penetrating limbo-keratoplasty....

OBJECTIVE To report the results of penetrating keratoplasty performed by residents. METHOD A retrospective medical record review of all patients undergoing penetrating keratoplasty performed by residents at our institution from April 1998 to April 2002. RESULTS Forty penetrating keratoplasty procedures were performed by 8 residents. The most common indication was keratoconus (17 eyes [43%])...

PURPOSE To determine the main causes of penetrating keratoplasty indications at "Hospital das Clínicas-UNICAMP" (January, 1999 to December, 2003). METHODS A non-comparative, retrospective series of case studies. The authors reviewed the files of 857 patients who underwent penetrating keratoplasty at "Hospital das Clínicas-UNICAMP" between 1999-2003 and classified them into different categorie...

The long-term follow-up of patients undergoing penetrating keratoplasty for pseudophakic corneal oedema is reported. The cause and frequency of corneal decompensation following intracapsular cataract extraction with insertion of an iris supported lens was assessed and found to be unrelated to the implant in the majority of cases. The most common cause of decompensation was endothelial touch dur...

BACKGROUND Using a rat penetrating keratoplasty model, this study aims to explore the inhibitory effect of hachimycin on corneal graft rejection, to provide new basis for its clinical application. MATERIALS AND METHODS Female adult Sprague-Dawley (SD) rats weighing between 220-250 g were used as acceptors and male or female Wistar rats weighing between 220-250 g were used as donors. The rats ...

purpose: to report a case of recurrent keratoconus after penetrating keratoplasty (pk). patient and findings: a 31-year-old male patient who had undergone pk in his right eye for keratoconus 10 years ago presented with gradually decreased vision in the right eye. clinical, topographic, and histopathologic features of the cornea including irregular myopic astigmatism, central and paracentral cor...

purpose: to report the outcomes of graft refractive surgery (grs) together with clear-cornea phacoemulsification and intraocular lens (iol) implantation in post-penetrating keratoplasty (pkp) eyes. methods: fourteen eyes of 13 patients who had received pkp underwent simultaneous grs (relaxing incisions with or without counter-quadrant compression sutures) and clear-cornea phacoemulsification wi...

PURPOSE To evaluate the data of penetrating keratoplasty over a 10-year period and to compare indications and outcomes of eyes undergoing single graft with those of eyes requiring regrafting. METHODS A total of 652 eyes of 613 patients required single graft (Group I). Sixty-one regrafts were performed on 53 eyes (Group II). The mean follow-up time was 23.4+/-21.3 months (range 6-132 months). ...
