5. Study Description
Brief Summary
The goal of this clinical trial is to compare the quality of corneal grafts cultured in a serum-free culture medium with a defined composition versus corneal grafts cultured in a standard serum supplemented culture medium transplanted in patients with decompensated corneal dystrophy
Detailed Description
The primary objective of this clinical trial is to test the equivalence of the quality of the corneal grafts cultured under serum free conditions to corneal grafts cultured in the Minimal Essential Medium supplemented with 2% fetal calf serum, based on a parallel comparison of the endothelial cell density of paired corneal grafts deriving from single donors at different time points before and after the grafting procedure. In addition, the safety of the clinical use of corneal grafts cultured in both media will be determined. The graft survival rate during the follow-up period will be quantified in regard to immune mediated graft rejection and non-immune mediated graft failure, as well as the incidence of corneal edema, corneal opacities and corneal neovascularisation.
