Lacrima VR for Dry Eye Disease and Meibomian Gland Dysfunction

A Randomized, Masked (Evaluator), Sham-Controlled, Prospective Study to Evaluate the Safety and Effectiveness of the Lacrima VR System in Subjects With Dry Eye Disease and Meibomian Gland Dysfunction

This is a prospective, multi-center, randomized, sham-controlled clinical investigation designed to evaluate the safety and effectiveness of the Lacrima VR system in adult subjects with Dry Eye Disease (DED) and Meibomian Gland Dysfunction (MGD). Subjects will be randomized in a 1:1 ratio to receive either active Lacrima VR treatment or a sham device with reduced luminance. Effectiveness will be assessed primarily by change in Tear Break-Up Time (TBUT), and safety will be evaluated by the incidence of device-related adverse events.

Dry Eye Disease (DED) and Meibomian Gland Dysfunction (MGD) are common ocular surface disorders associated with tear film instability, ocular discomfort, and impaired visual function. The Lacrima VR system is a non-invasive medical device that delivers controlled sequences of light pulses using virtual reality technology, intended to activate reflex pathways associated with lacrimal and meibomian gland function.

This randomized, evaluator-masked study compares the Lacrima VR system with a sham device that is identical in appearance but operates at substantially reduced luminance. Subjects will undergo four treatment sessions at two-week intervals, followed by follow-up visits at 4 and 10 weeks after the final treatment. Effectiveness will be assessed using objective measures (TBUT) and patient-reported outcomes (OSDI). Safety assessments will include monitoring of adverse events, intraocular pressure, visual acuity, and discomfort questionnaires.
