Quantum Molecular Resonance Electrotherapy in Severe Dry Eye Disease

In this prospective, interventional study, 81 patients were randomly allocated to received 4 treatment sessions of QMR at one-week intervals (Rexon-Eye ® , Resono Ophthalmic, Trieste, Italy) (QRM group) or tear substitute 4 times daily, containing 0.15% sodium hyaluronate and 3% trehalose (Thealoz Duo ® , Thea Pharma, France) (SH-TH group). Outcomes measures included ocular surface disease index (OSDI) questionnaire, tear meniscus height (TMH), tear breakup time (TBUT), non-invasive breakup time (NIBUT), corneal fluorescein staining (CFS), lipid layer thickness (LLT), tear film osmolarity (OSM) and meibomian gland dysfunction (MGD) grade, which were assessed at baseline, 1-month and 3-months follow-up.
