The Belgian Endothelial Surgical Transplant of the Cornea

This study is designed as a randomised multicentric parallel group pragmatic trial of Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) versus Descemet Membrane Endothelial Keratoplasty (DMEK) in corneal endothelial decompensation. the purpose is to compare the clinical and patient reported outcomes of both therapies across a broad range of indications.

The current problem concerns variability in the provision of corneal endothelial keratoplasties available to patients in Belgium. Some patients receive DSAEK and some (albeit fewer) receive DMEK. Currently the type of corneal graft that a patient receives depends on the treating surgeon opinions. In this study 220 patients in 11 surgical centres will be recruited and allocated to one of the two surgical options. Both the Ultrathin DSAEK and DMEK grafts will be prepared by corneal banks in the University Hospital of Liege and University Hospital of Antwerp respectively. Patients will be examined preoperatively and postoperatively at 3, 6 and 12 months. Clinical information such as best-corrected visual acuity and refraction will be collected as well as quality of life information based on the EQ-5D-5L and the VFQ 25 assessment tools. These data be used to compare the interventions both on the clinical level as well as from the patient perspective.
