| Popis: | OBJECTIVES We evaluated 23 years of data for cornea donors at the Istanbul Faculty of Medicine Lions Eye Bank. MATERIALS AND METHODS Annual statistics of corneal donors between 1996 and 2019 were reviewed retrospectively. Records for 2008 and previous years were compared with records for 2009 and years thereafter,to assess donor demographics and reasons for discard of corneas. RESULTS A total of 3849 corneas were obtained from 2018 donors during a 23-year period. Of these, 26 donors (11.2%) were registered, whereas 1792 (88.8%) did not register any decision for donation. There were 210 (5.46%) corneas discarded for positive serology and 291 (7.56%) for unsuitable tissue morphology, and 3348 (86.98%) corneas were determined to be suitable for transplant. For the cause of death in 2009 and subsequent years, the incidence of trauma was lower (P = .001) compared with the years previous to 2009, whereas incidence of cardiac pathology (P = .014) was higher. The number of donors older than 50 years was higher for 2009 and years thereafter, compared with data from earlier years (P = .024). The rate of discarded corneas for unsuitable tissue morphology (P = .004) and total discarded corneas (P = .027) decreased in 2009 and years thereafter. The rate of discarded corneas for HIV was higher after for 2009 and years thereafter (P = .047), whereas the rate of discarded corneas for syphilis was significantly higher for 2015 and years thereafter (P = .001). CONCLUSIONS This study evaluated the most extensive eye bank data in Turkey and found that advances in lamellar surgery techniques and improvements in specular microscopic facilities have expanded the pool for cornealtransplants to include tissues from older donors. Moreover, the incidence rates for HIVpositive and syphilis-positive serology tests in discarded corneas have increased over time. |
