A slice of donor cornea may patch thinning eyes — a trial puts it to the test

NCT ID NCT04848740

First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time

Summary

This trial tests whether implanting a thin layer of fresh donor corneal tissue — complete with living cells — can thicken the cornea and improve vision in people with progressive corneal disease. Using a femtosecond laser, surgeons create a pocket in the patient's cornea and insert the lenticule. The study will measure changes in corneal thickness and transparency.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a fresh human corneal lenticule (stromal tissue with stem cells and live keratocytes) implanted into the cornea using the ReLex-Smile femtosecond laser technique
What this could lead to
If it works, this could offer a way to restore corneal thickness and transparency in people with progressive corneal disease, potentially improving vision without a full corneal transplant.
What could go wrong
This is an early-stage, non-randomized trial with no control group. Risks include infection, graft rejection, or failure to improve vision. Long-term safety and effectiveness are not yet known.
