Summary
Brief summary
Microbial keratitis is a significant cause of ocular morbidity and visual loss, as well as a significant health cost to the community. Ultraviolet light is known to be microbicidal. We think it is likely that the proposed treatment will lead to quicker recovery from this serious eye infection and better visual outcomes.
