Lacrima VR for Dry Eye Disease and Meibomian Gland Dysfunction (CLN-0154)

May 11, 2026 updated by: Demaod Ltd

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.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Experimental: Active Lacrima VR
Participants receive treatment using the Lacrima VR headset delivering controlled light pulse sequences at a luminance of approximately 125 cd/m². Four treatment sessions are administered at two-week intervals.
Device: Lacrima VR System
This is a prospective, randomized, sham-controlled, evaluator-masked 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). Eligible participants will be randomized in a 1:1 ratio to receive either active Lacrima VR treatment or a sham device with reduced luminance. The intervention consists of four non-invasive treatment sessions administered at two-week intervals using a virtual reality headset that delivers controlled sequences of light pulses. All participants will undergo standardized ophthalmic assessments and patient-reported outcome evaluations at baseline and at predefined follow-up visits conducted 4 and 10 weeks after the final treatment session. Safety will be assessed throughout the study by monitoring adverse events, discomfort, and changes in ocular parameters.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Tear Break-Up Time (TBUT) at 4 Weeks
Time Frame: Baseline to 4 weeks after final treatment
Change from baseline to the 4-week follow-up in Tear Break-Up Time (TBUT) will be assessed as an objective measure of tear film stability. TBUT will be measured in seconds using fluorescein dye by a masked evaluator who is not involved in treatment administration. The outcome is defined as the change from baseline in TBUT at specified follow-up visits, with measurements averaged across repeated assessments per eye.ear Break-Up Time (TBUT), measured in seconds by a masked evaluator.
Baseline to 4 weeks after final treatment

Secondary Outcome Measures

Secondary Outcome Measures
