First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether a specific hands-on technique inside the mouth can increase tear production in healthy adults aged 18-45. Thirty volunteers will have their tears measured before and after the procedure, with follow-up visits at 2 days and 1 week. The goal is to see if this simple, non-invasive method could help people with dry eyes.
