Objectives: To evaluate the efficacy of Eusol-C as a corneal storage medium on the survival of donor endothelium.
Materials and Methods: Twenty-seven corneas not suitable for transplant were included in this study. All donor corneas were stored in Eusol-C at 4°C. Daily donor corneal endothelial cell counting was performed with an eye bank specular microscope. All corneas were discarded after the study process.
Results: Mean donor age was 51.3 ± 18.8 years (range, 25-94 y). The mean duration between death and corneal excision was 9.5 ± 6.7 hours (range, 3-23 h). Mean endothelial cell density was 2195 ± 383 cells/mm² at the beginning of the preservation (range, 1361-2899 cells/mm²). Donor endothelial cell density was between 1500 to 2000 cells/mm² in 9 corneas, 2000 to 2500 in 11 corneas, 2500 to 3000 in 5, and higher than 3000 in 2 corneas at baseline. Mean endothelial cell density was found 1658 cells/mm² on the eighth day of storage, with a mean endothelial cell loss rate of 24.5%. Corneas stored 9 to 24 days in Eusol-C had a rate of endothelial cell damage of 3.1% per day.
Conclusions: Although our results revealed a higher endothelial cell loss than previous reports, overall performance of Eusol-C in preserving the donor endothelium may be satisfactory for clinical use.
