Study Details
Study Description
Brief Summary
A Randomized, Masked (Evaluator), Controlled, Prospective Study Evaluating the Effectiveness and Safety of the Tixel® Medical Device, Versus LipiFlow® in the Treatment of Meibomian Gland Dysfunction

N/A |
Detailed Description
A randomized, open-label study comparing the Tixel device to LipiFlow® System. Up to 110 patients (220 eyes) to be randomized in up to 4 clinical sites in Europe and Israel.
Evaluators will be masked as to the randomization assignments. Both eyes will receive the same randomized assignment and both eyes of each patient will be evaluated at all time points.
Data from both eyes will be used in the statistical analysis. The random-effects model adjusts the standard error (SE) and the confidence interval (CI) for within-person correlation between eyes.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tixel Group Screening and baseline visits, Treatment- 3 treatment sessions, followed by 2 Follow up sessions, 1and 3 months after the last treatment visit. Subject will be questioned about Discomfort and Pain Questionnaires (self-assessed) and OSDI questionnaire. |
Device: Tixel C
Tixel C by Novoxel®, Israel is a thermomechanical system developed for fractional treatment. The system is designed for the treatment of soft tissue by direct conduction of heat, enabling tissue coagulation combined with micro ablation with low thermal damage to the surrounding tissue.
|
| Active Comparator: LipiFlow LipiFlow: Screening and baseline visits,Treatment session, followed by 2 Follow up sessions, 1and 3 months after the last treatment visit. Subject will be questioned about Discomfort and Pain Questionnaires (self-assessed) and OSDI questionnaire. |
Device: LipiFlow
Thermal pulsation (LipiFlow) consists of the localized application of heat and therapeutic pressure on the four eyelids (upper and lower) with the aim of improving drainage of the Meibomian glands.

Outcome Measures
Primary Outcome Measures
- Changes in Tear Break Up Times (TBUT) to the 4-weeks follow-up exam [Up to 18 months include Follow up visits.]
Change from baseline to the 4-weeks follow-up exam in Tear Break Up Times (TBUT)
- Comparison of the incidence of device-related Ocular adverse events [Up to 18 months include Follow up visits.]

Secondary Outcome Measures
- Changes in patient OSDI [Up to 18 months include Follow up visits.]
Changes from baseline in patient symptoms using Ocular Surface Disease Index (OSDI) at 4-weeks and 12-weeks follow-up exam. OSDI is assessed on a scale of 0 to 100, with higher scores representing greater disability. A patient's score between 1-12 is defined as normal, A patient's score between 13 - 22 is defined as mild, A patient's score between 23 - 32 is defined as moderate, and a patient's score between 33 - 100 is defined as severe dry eye diseases.
- Changes in Tear Break Up Times (TBUT) to the 12-weeks follow-up exam [Up to 18 months include Follow up visits.]

Change from baseline to 12-weeks follow-up exam in Meibomian Gland Score (MGS).
- Adverse events [Up to 18 months include Follow up visits.]
The evaluation of discomfort and pain during treatment.(VAS score of 1-10)
