A device that zaps nerves inside the nasal cavity can significantly reduce symptoms of dry eye disease, a multifactorial disease that can be difficult to treat, researchers report.
The procedure involves a neurostimulator – consisting of a reusable base that produces microcurrents, a disposable tip that inserts in to the nasal cavity, and a battery charger – which delivers microcurrents to the trigeminal nerve in the nasal cavity, inducing endogenous tear production through the nasolacrimal pathway.
