Primary Outcome Measures:

The primary outcome is the endothelial cell density of the corneal grafts prior to and after the transplantation procedure [ Time Frame: The measurment will be performed prior to and 1, 4, 12, 24, 36, 48 and 60 months after the transplantation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Secondary study outcomes are immune mediated graft rejection, non-immune mediated graft failure, as well as the incidence of corneal edema, corneal opacities and corneal neovascularisation. [ Time Frame: 1,4,12, 24, 36, 48 and 60 month after the transplantation ] [ Designated as safety issue: No ]

Estimated Enrollment:	60
Study Start Date:	April 2011
Estimated Study Completion Date:	October 2012
Estimated Primary Completion Date:	April 2012 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: 1 Patients in this arm randomly receive a corneal graft cultured in a serum free culture medium	Procedure: Corneal transplantation Full thickness penetrating keratoplasty
Active Comparator: 2 Patients in this arm randomly receive a corneal graft cultured in a serum supplemented culture medium	Procedure: Corneal transplantation Full thickness penetrating keratoplasty

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.
