New eye drop shows promise for rare corneal disease
NCT ID NCT04485546
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an eye drop called OXERVATE in 37 adults with stage 1 neurotrophic keratitis, a condition where the cornea loses feeling and doesn't heal properly. The treatment was given for 8 weeks, and patients were followed for 24 weeks to see if the cornea healed safely. The main goal was to check how many patients had complete corneal healing.
