The iTEAR Extranasal Neurostimulator is a non-invasive, drug-free device designed to improve natural tear production for the management of dry eye disease. Cleared by the U.S. FDA, iTEAR uses gentle mechanical vibration to stimulate the external nasal nerve, activating the lacrimal functional unit and encouraging the eyes to produce their own natural tears.
By stimulating the trigeminal nerve pathway, iTEAR promotes secretion from the lacrimal glands, meibomian glands, and conjunctival goblet cells, supporting the production of the aqueous, lipid, and mucin components of the tear film. The rechargeable device requires no consumables or ongoing running costs, making it a convenient long-term solution for dry eye management.
iTEAR delivers gentle mechanical vibrations to the external nasal nerve at the junction of the nasal cartilage and bone. This stimulation activates neural pathways connected to the lacrimal functional unit, triggering natural tear production and supporting a healthier, more stable tear film.
Locate the treatment area at the junction between the nasal cartilage and the nasal bone.
Hold the device parallel to the face and gently place it on the treatment area without applying pressure.
Stimulate each side of the nose for 30 seconds, twice daily.
