To evaluate the affecting factors for graft rejection and graft failure in PKP with imported donor corneas
This is retrospective study that include 110 eyes which PKP with imported donor cornea . Mean follow up period was 18months. Correlation of the graft failure and graft rejection with the following factors were analyzed : donor age, donor sex, donor cause of death, endothelial cell count at the moment of preservation, death-to-preservation time, preservation to surgery time
54 eyes graft rejection and 42 eyes graft failure occurred. Mean endothelial cell count of imported donor corneas at the moment of preservation was 2887 ± 432 cells/mm2, death to preservation time 9.1 ± 4.8 hours, preservation to surgery time 130.0 ± 25.0 hours. There was no significant correlations between surgical outcome and donor age, donor cornea endothelial cell count, death-to-preservation time, preservation to surgery time.(p=0.952, p=0.522, p=0.335, p=0.616)
Environmental change and long preservation time of imported donor cornea does not affect surgical outcome
