Trial Outcomes & Findings for Evaluate the Safety and Effectiveness of The Tixel Fractional System in the Treatment of Meibomian Gland Disfunction (NCT NCT04889950)

NCT ID: NCT04889950

Last Updated: 2024-11-15

Results Overview

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

Timeframe: 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).

Population: Tixel subects and lipiflow subjects completed baseline, 4 weeks OSDI and 12 weeks OSDI.

Change from baseline in patient symptoms using Ocular Surface Disease Index (OSDI) at 4-weeks and 12-weeks follow-up exam. The Ocular Surface Disease Index (OSDI) is a questionnaire designed to assess the severity of dry eye disease. OSDI Questionnaire The questionnaire consists of 12 questions divided into three subscales: Ocular Symptoms Visual Functioning Environmental Triggers Scoring System The scoring for the OSDI is based on a scale from 0 to 100, where higher scores indicate more severe symptoms. Each question is scored as follows: 0: None of the time 1. Some of the time 2. Half of the time 3. Most of the time 4. All of the time Interpretation of OSDI Scores The OSDI scores are generally interpreted as follows: 0-12: Normal or no dry eye 13-22: Mild dry eye 23-32: Moderate dry eye 33-100: Severe dry eye

The Meibomian Gland Score (MGS) is a clinical tool used to evaluate the function of the meibomian glands. Scoring Criteria Each gland is assessed and scored based on the quality of the expressed secretion: 0: No secretion 1. Inspissated 2. Cloudy 3. Clear liquid Interpretation of MGS Minimal MGS score = 0 in each eye (15 glands evaluated in each eye) Maximal MGS score = 45 in each eye (15 glands evaluated in each eye) Low MGS: (below 12) Indicates poor function or obstruction of the meibomian glands, suggesting MGD.
