purpose: to evaluate the influence of donor characteristics (age, death-to-preservation time, preservation-to-surgery time, graft rating, and endothelial cell features) on clinical outcomes following deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this retrospective study, 290 consecutive keratoconic eyes underwent dalk using donor corneas of different quali...

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...

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, ...

conclusions we found acceptable short-term survival in both groups; however, living donor recipients continue to have better long-term patient and graft survival rates. results although there were no significant differences in one-year survival rates of patient and graft between study groups, three-years survival rates of patient and graft were significantly longer in living donor kidney transp...

background and aims. localized gingival recession presents as a special therapeutic problem. subjective parameters and donor site morbidity are often overlooked while deciding on any treatment option. materials and methods. 22 subjects were equally divided in group a (lateral pedicle graft) and group b (free mucosal graft). subjective evaluation of post operative sensitivity, discomfort and ble...

Service quality has been recognized as a strategic tool for improving organizational performance. Many non-profit organizations have taken a market-based approach to fundraising, which enhances the importance of service excellence. The purpose of this investigation was to examine donor perceptions of service quality in college athletics. First, an adapted version of Sargeant’s (2001) non-profit...

Disparities in both access to the kidney transplant waiting list and waiting times for transplant candidates have been extensively documented with regard to ethnicity, gender, socioeconomic factors, and region. However, the issue of access to equivalent quality organs has garnered less attention. The principal aim of this study was to determine whether certain patient populations were more like...
