New eye drop could heal corneal wounds that Won't close

This study tests an eye drop containing a human nerve growth factor (cenegermin) to see if it can heal persistent corneal epithelial defects (PCED) — stubborn wounds on the eye's surface that haven't healed with standard treatments. About 150 adults with PCED will receive either the active eye drop or a placebo for up to 16 weeks, and doctors will check if the cornea is fully healed after 4 weeks. The goal is to find a safe and effective way to close these hard-to-treat eye injuries.
