Official title: Effect of Descemet Membrane Polishing in Fuchs Endothelial Corneal Dystrophy
Run by Centre Hospitalier Universitaire de Saint Etienne · NCT07539012 · Data updated 2026-11-12
This trial tests whether polishing the diseased Descemet membrane before injecting cultured endothelial cells helps improve graft adhesion and outcomes for people with Fuchs endothelial corneal dystrophy.

Is this trial a fit for you?
✓Likely a good fit
Adults with Fuchs endothelial corneal dystrophy scheduled for endothelial keratoplasty who can provide informed consent.
✕Probably not a fit
Patients whose corneal pathology or overall eye health limits benefit from this approach or who do not respond to endothelial cell therapy may not experience improvement.

What this trial studies
This interventional study in patients with Fuchs endothelial corneal dystrophy evaluates the effect of Descemet membrane polishing prior to endothelial cell injection. Eligible participants are adults undergoing endothelial keratoplasty who can provide informed consent. The intervention involves polishing the pathological Descemet membrane to remove guttae before cell therapy, with outcomes focused on graft adhesion and cell survival. The study is conducted at multiple centers in France, led by CHU Saint-Etienne, to determine whether this step enhances treatment effectiveness. Safety and feasibility data will be collected to inform future adoption of the approach.
Why it matters
Potential benefit: If successful, polishing the Descemet membrane could improve graft adhesion and survival of transplanted endothelial cells, potentially leading to better vision for FECD patients.
How similar studies have gone: Previous reports on endothelial polishing have shown mixed results, so this in vivo evaluation is needed to determine effectiveness.
