Observational study shows similar graft survival rates and visual outcomes in corneas from different sources, suggesting need for further exploration of failure rates.
Graft survival rates and visual outcomes did not differ between imported and domestic corneas, despite significant baseline differences, which include preoperative endothelial cell count, death-to-preservation time, and death-to-transplant time. A trend toward higher primary failure rates with imported corneas warrants further investigation.
