Summary

This study tests whether adding a light-activated dye (rose bengal) to standard antibiotic drops helps people with severe bacterial eye infections see better after 6 months. About 60 adults with moderate to severe vision loss from a corneal ulcer will receive either antibiotics plus the light treatment or antibiotics plus a sham light treatment. The goal is to see if the light treatment reduces scarring and improves vision.
