LipiFlow is a novel treatment device for meibomian gland dysfunction and evaporative dry eye syndrome. The meibomian glands are responsible for producing an oil layer to the tears that prevents the tears from evaporating. If the meibomian glands become obstructed oil will not flow from them, causing dry eye symptoms. The LipiFlow activator opens obstructed meibomian glands by gently warming the inside of the eyelids while applying light pulsatile pressure to the outer eyelids to remove hardened oils. This restores normal function to the meibomian glands and relieves dry eye symptoms.
