Corneal donation for research versus for transplantation: A-year prospective study of acceptance rates in a French University Hospital

Fresh corneal donation is essential for basic and preclinical research, but more unknown to public and the medical teams than donation for transplantation: it may raise concerns. We prospectively compared the acceptance rates and the characteristics of targeted corneal donation for research versus donation for transplantation during one year. The Agence de la Biomédecine authorized us to procure fresh corneas targeted for research, only from the donors with medical contraindications for transplantation, in order not to increase grafts shortage. Three nurses from the hospital coordination team of Saint-Etienne University Hospital, obtained consent for research and transplantation in parallel, screening all intra-hospital deaths cases, following standard protocol to check no refusal from families, despite the French opt-out system. They contacted 127 families for research and 244 for transplantation, in 71% of cases by telephone. Consent was obtained in 62% of cases for research and 54% for transplantation (P = 0.135). The main contraindication for transplantation was the cognitive disorders (66%) followed by the blood cancers (8%). This new specific activity, providing new source of fresh corneas for research immediately usable without any eyebank storage steps, didn’t reduce the number of corneas procured for transplantation versus previous years (P = 0.998). Donors in the research group were 10 years older (P
