Brief Summary:
The purpose of this study is to investigate whether electrical stimulation of the nerve innervating the tear gland results in tear production in subjects with severe Dry Eye.

Condition or disease Intervention/treatment Phase
Dry Eye Device: Electrode device Not Applicable

Detailed Description:
A non-randomized, open-label study designed to investigate the feasibility of a novel treatment for severe Dry Eye Disease, which involves safe delivery of small electrical currents to the lacrimal nerve to induce tear production.
