5. 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
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.
