简要总结
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
详细描述
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.

结局指标
主要结局
Changes in Tear Break Up Times (TBUT) to the 4-weeks Follow-up Exam
时间窗: Tixel arm: Baseline and 4 weeks after last treatment (8 weeks post baseline). LipiFlow arm: Baseline and 4 weeks after treatment (4 weeks post baseline).
Change from baseline to the 4-weeks follow-up exam in Tear Break Up Times (TBUT), as assessed by a masked rater. TBUT - Tear Break-Up Time, is a clinical test used to evaluate the stability of the tear film on the surface of the eye. It measures the time it takes for dry spots to appear on the cornea after a blink. A shorter TBUT indicates a more unstable tear film, which can be a sign of dry eye disease or other ocular surface disorders. Tear Break-Up Time (TBUT) is typically scored by the time (in seconds). The general interpretation of TBUT scores is as follows: Normal TBUT: More than 10 seconds Borderline TBUT: 5 to 10 seconds Abnormal/Low TBUT: Less than 5 seconds
Comparison of the Incidence of Device-related Ocular Adverse Events
时间窗: Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).
