Summary

This trial tests whether implanting a fresh, donated corneal lenticule into the eye can reshape the cornea and reduce irregular astigmatism in people who have already had a full cornea transplant. The goal is to improve visual acuity and stabilize the cornea's shape. Twenty-four participants with irregular astigmatism and low vision will receive the implant using a minimally invasive SMILE surgery technique.

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 implanted into the cornea to reshape it
What this could lead to
If it works, this could offer a new way to improve vision and reduce astigmatism in people who have already had a cornea transplant.
What could go wrong
This is a small, early-stage trial with only 24 participants. The procedure carries risks such as infection, inflammation, or the implant not improving vision as hoped.
