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

Detailed Description

Randomized, open-label study comparing the Tixel device to LipiFlow System. Up to 110 patients (220 eyes) to be randomized in up to 5 clinical sites in the United States.

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 using in the statistical analysis. The random-effects model adjusts the standard error (SE) and the confidence interval (CI) for within-person correlation between eyes.

Protocol Rev. 7.0 update: Addition of protocol extension to the current protocol: stage 1- main protocol for all patients and stage 2- extension protocol to a sub-group of patients only in the Tixel arm for additional follow-up visit 6 months post last treatment.

Conditions

Meibomian Gland Dysfunction; Dry Eye Syndromes; Dry Eye

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

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.

Group Type: EXPERIMENTAL

Tixel C

Intervention Type: DEVICE

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.

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.

Group Type: ACTIVE_COMPARATOR

LipiFlow

Intervention Type: DEVICE

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.
