Dry Eye, Meibomian Gland Dysfunction
Conditions
Brief summary
This study is a multicentric, comparative, randomized, investigator-blinded, in parallel groups study to demonstrate the non-inferiority of Neovis® Total Multi in comparison with Systane® Balance, in terms of improvement of stability of Tear film in patients with eye dryness associated to meibomian gland dysfunction, after 28 days of treatment.
Interventions
