Quantum Molecular Resonance Electrical Stimulation as a Beneficial and Safe Treatment for Multifactorial Dry Eye Disease

Introduction: To assess the clinical benefits obtained with transcutaneous low-power, high-frequency quantum molecular resonance (QMR) electrotherapy in a group of multifactorial dry eye patients. Methods: Fifty-one patients (total of 102 eyes) with dry eye symptoms were enrolled in the study. Included clinical conditions were meibomian gland dysfunction, glaucoma, cataract surgery within the past six months, and autoimmune disease-related superficial punctuate keratitis. The QMR treatment was administered using the Rexon-Eye device (Resono Ophthalmic, Sandrigo, Italy) for four consecutive weeks, with one 20-minute treatment session per week. The measured ocular parameters included non-invasive tear break-up time (NIBUT), corneal interferometry, lower eyelid meibography, and tear meniscus height, all measured at baseline, at the end of treatment, and two months after the end of treatment. The Ocular Surface Disease Index (OSDI) questionnaire was gathered at the same time. The study has received approval from our institution’s ethics committee. Results: At the end of treatment, interferometry, tear meniscus height, and OSDI score improved at a statistically significant level. No statistically significant change was observed in NIBUT or meibography. At two months after the end of treatment, all parameters showed a statistically significant improvement, namely NIBUT, meibography, interferometry, tear meniscus, and OSDI score. No adverse events or side effects were reported. Conclusions: The QMR electrotherapy by the Rexon-Eye device shows statistically significant improvement of dry eye clinical signs and symptoms with a duration of at least two months.
