In this study, the investigators aim to examine the efficacy of the Rexon eye device for the treatment of dry eye signs and symptoms in a randomized double-blind placebo-controlled fashion among a cohort of prospectively recruited patients with dry eye. The control group will receive a similar application of treatment with the device goggles disconnected from the device, effectively receiving no treatment. The treatment will be performed by research assistants following thorough instruction by the manufacturing company representatives and/or provided material. Participants will be actively questioned on any harms or side effects in every meeting.~Outcomes will be assessed based on clinical signs and by validated questionnaires on dry eye symptoms (OSDI).~Informed written consent will be obtained from all participants involved in the study prior to enrollment. The goal of the study is to evaluate the Rexon device as a possible additional treatment option for patients with dry eye or to establish it has no added benefit.
The Rexon Eye device (Resono Ophthalmic Inc, Trieste, Italy) is a new device based on QMR technology. Quantum Molecular Resonance (QMR) is a technique in which low-intensity, high-frequency electric currents are administered to a biological tissue through contact electrodes. The device applies stimulation to the epidermis of closed eyelids up to the lid margin by means of specially designed goggles. Previous studies have shown that it is relatively safe with high patient satisfaction. Preliminary studies have also shown it is effective for accelerating healing in chronic wounds and treating dry eye symptoms.
