The LipiFlow™ Thermal Pulsation System is designed to treat Dry Eye Disease resulting from MGD, or Meibomian Gland Disorder, a common cause of Dry Eye discomfort. The Meibomian glands, which are located in the upper and lower eyelids, secrete meibum, a protective lipid layer that prevents evaporation of the aqueous tear film. At times, these glands can become obstructed, causing ocular irritation and dry eye resulting from rapid evaporation of the aqueous tear film, which protects your eyes by keeping them lubricated.
