NCT05692739

Brief Summary

This is a parallel randomized controlled trial for the treatment of dry eye disease. The main objective is to investigate the efficacy and safety of the use of insulin eye drops in the control of moderate-severe dry eye disease. Topical insulin drops will be compared to the current gold standard treatment, cyclosporin and placebo (artificial tears).
