About this study
This study is a non-randomized, open-label, interventional trial of TearCare® eyelid warming and manual meibomian gland expression in young adults with clinically significant meibomian gland dysfunction (MGD). Intervention is with TearCare® performed at Visit 1. A single follow-up examination occurs at Day 28.
Read the detailed description
This study is a non-randomized, open-label, interventional trial of TearCare® eyelid warming and manual meibomian gland expression in young adults with clinically significant MGD. Intervention is with TearCare® performed at Visit 1. A single follow-up examination occurs at Day 28.
The primary objective is to evaluate the safety and efficacy of TearCare® in teenage and young-adult patients with MGD. A secondary objective includes a predictive analysis to determine which baseline clinical parameters best predict success with a TearCare treatment.
Co-primary efficacy endpoints include change from baseline in non-invasive keratograph break-up time (NIKBUT) at Day 28 and change from baseline in ocular surface disease index (OSDI) at Day 28. Secondary endpoints include the proportion of subjects with pre-defined baseline clinical characteristics who experience a clinically meaningful improvement in NIKBUT or OSDI. Exploratory endpoints include change from baseline in Dry Eye-Related Quality of Life Score (DEQS) at Day 28. The primary safety endpoint is the incidence of adverse effects that are probably or definitely related to the intervention.
The study population will include 45 young adults with clinically significant MGD (30 participants who are ≥18 to <22 years of age and 15 participants who are ≥22 to <30 years of age). The study duration is 4 weeks. TearCare® eyelid warming and manual gland expression will be performed once at Visit 1.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TearCare®Device
The TearCare system is designed to deliver controlled, precise heat to the tarsal plates and underlying MGs of the eyelids for 15 minutes. The TearCare system comprises a reusable Smart-hub and single-use Smart-lids. The single-use Smart-lid pair comprises four flexible, sensor-controlled strips that adhere to each of the four eyelids. They contain flexible circuits, sensors, and a microprocessor which provide accurate and precise thermal energy to the eyelids to melt oil in the meibomian glands. Medical-grade adhesive on the skin-facing surface of the Smart-lids allows them to be affixed to the external surface of the eyelids during the procedure and easily removed at the end of the procedure. The Smart-lids are connected to the Smart-hub. When attached to the Smart-hub, the Smart-lids deliver thermal energy (i.e., heat) to the eyelids. Embedded software and a closed loop sensor system ensure that the temperature delivered at the eyelids is maintained within a precise range.
| Study group | Role | What they receive |
|---|---|---|
| Treatment | Experimental | TearCare® eyelid warming and manual gland expression performed once at Visit 1 and followed for 4 weeks. All participants will undergo standardized ocular assessments including OSDI questionnaires, non-invasive keratograph break-up time, Habitual High contrast LOGMAR Visual Acuity, Bio microscopy, posterior lid margin hyperemia, Fluorescein tear break-up time, corneal fluorescein staining, conjunctival staining with lissamine green, lid wiper epitheliopathy with lissamine green, Surveys - DEQS, SANDE, Screen time-use, Lipview II lipid imaging, Keratograph R-scan, Keratograph Meibography, meibomian gland expression by meibomian gland evaluator. Receives: Device: TearCare® |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ocular Surface Disease Index (OSDI) Score From Baseline to 4 Weeks
The Ocular Surface Disease Index (OSDI) is a 12-item questionnaire used to assess dry eye symptoms and their impact on vision-related functioning. Total scores range from 0 to 100, with higher scores indicating greater symptom severity and worse outcomes. The change in OSDI score from baseline to Week 4 will be assessed.
Measured: Baseline to 4 weeks
Non-Invasive Keratograph Break-Up Time (NIKBUT) From Baseline to Week
Non-Invasive Keratograph Break-Up Time (NIKBUT) refers to an imaging modality used to image the pre-corneal tear film and measure the time it takes for the tear film to destabilize or break up. Change in NIKBUT from baseline to Day 28 will be assessed.
Measured: Baseline to Week 4
