Analysis of the cornea donor data: an eye bank study

Abstract

Objectives. To analyse 1.5-year data of our newly established eye bank and to evaluate the factors affectingdonor quality. Methods. Our bank's donor cornea data between July 2013 and November 2014 were retrospectively analysed. The effects of donor age, sex, and time from death to harvesting on the findings of specularmicroscopy were assessed. Results. A total of 139 corneas retrieved from 70 donors. The mean age of donorswas 34.2±14.6 years. The mean time from death to harvesting was 6.7±2.9 hours; the mean timefrom collection to transplantation was 5.2±2.8 days. Age had a significant negative correlation withmean endothelial cell count (ECC), a significant positive correlation between mean cell area (MCA) and standard deviation (SD). Time from death to harvesting had a significant negative correlation with cell count and6A; it had a significant positive correlation with SD, the coefficient of variation, and MCA. Conclusion. According to the results of the present study, ECC, MCA, and SD levels were greater in younger donors. Endothelial morphology was altered as the time from death to harvesting was prolonged; however, the alterationin cell morphology was not severe enough to alter transplantation success with the corneas being harvestedwithin the first 13 hours.
