35 Review on endothelial cell loss of corneal transplants and possible correlations.

The Tissue Bank of the Upper Austrian Red Cross in Linz, Austria, is a multi-tissue bank, processing corneal transplants (for PKP, for DMEK, pre-cut DMEK), homografts (aortic valve, pulmonary valve, pulmonal patch), amnion grafts (frozen or cryopreserved), autologous tissues and cells (ovarian tissue, cranial bone, PBSC) as well as investigational medicinal products and ATMPs (Aposec, APN401).This presentation sums up retrospective data of the endothelial cell count of corneae at the time of first evaluation and at the time of reevaluation before transplantation as well as the cell count of pre-cut DMEK before transplantation.Regarding corneal grafts it is advisable to review the data of the previous years to find potential factors influencing the cell count of corneal tissue.
