Fuchs Dystrophy: What It Is and How It's Treated

What Is Fuchs Dystrophy?

Fuchs Endothelial Dystrophy is a progressive hereditary disorder affecting the endothelial layer of the cornea — the very thin row of cells responsible for pumping fluid out of the cornea and maintaining its clarity. When these cells deteriorate, fluid accumulates in the cornea, causing it to swell and gradually lose transparency.

Why Does It Affect Vision?

Morning blurriness is a hallmark symptom — vision improves through the day as natural evaporation occurs. As the disease progresses, the blurriness becomes permanent and painful blisters appear on the corneal surface (bullous keratopathy).

Stages of the Disease

Stage one: no symptoms. Stage two: morning blurriness that improves. Stage three: persistent blurriness. Stage four: blisters and pain — surgical intervention is required.

Treatment — From Drops to Endothelial Transplant

In early stages: hypertonic saline drops (Sodium Chloride 5%) reduce corneal swelling. In advanced stages: DMEK (Descemet Membrane Endothelial Keratoplasty) is the optimal treatment — replacing damaged endothelial cells with healthy donor cells while preserving the rest of the cornea.

Why DMEK Instead of PKP?

DMEK replaces only the endothelial layer (less than 0.015 mm) without disturbing the rest of the cornea — faster recovery, clearer vision, and significantly lower rejection risk than full-thickness transplant.
