LipiFlow is a medical treatment device used to manage meibomian gland dysfunction (MGD), one of the leading causes of dry eye disease. The meibomian glands, located in the eyelids, produce oils that form part of the tear film, preventing the eyes from drying out. When these glands become blocked or dysfunctional, it can lead to irritation, dryness, and inflammation. LipiFlow addresses this by using a combination of gentle heat and pulsating pressure to unclog and stimulate the glands.
