研究概览
简要总结
The purpose of this study was to compare changes in meibomian gland dysfunction (MGD), tear break-up time (TBT) and evaporative dry eye (EDE) symptoms after treatment with either the iLux® 2020 System or the LipiFlow® Thermal Pulsation System.
详细描述
At the Baseline visit (Day 0), subjects were assessed pre-treatment, during treatment, and post-treatment.

结局指标
主要结局
Change From Baseline to Week 4 in Tear Break-Up Time (TBT)
时间窗: Baseline, Week 4
Tear break-up time (defined as the time required for dry spots to appear on the surface of the eye after blinking) was assessed by the examiner using a slit lamp and fluorescein strips. Fluorescein was instilled onto the patient's eye, after which the patient blinked three times, then kept the eye open. Immediately thereafter, the examiner used a stopwatch to record the time between the last blink and the first appearance of a dark spot on the cornea (formation of dry area). Three consecutive measurements were taken and averaged for actual TBT. A positive change value represents a lengthening in the tear break-up time and greater comfort.
Incidence (Number) of Device- or Procedure-related Adverse Events
时间窗: Week 4
The number of device- or procedure-related adverse events was calculated, including changes from baseline (Yes/No) in any of the following eyelid characteristics: lid margin assessment or development of floppy eyelids or entropion (eyelid rolled inward) or ectropion (eyelid sagging outward) or loss of lash integrity.
Change From Baseline to Week 4 in Meibomian Gland Score (MGS)
时间窗: Baseline, Week 4
Meibomian glands on the lower eyelid were assessed by the examiner using a Meibomian Gland Evaluator while viewing the eyelid margin using a slit lamp microscope. 5 glands in 3 zones (nasal, medial, temporal) were evaluated. Each gland was scored from 0-3 for a maximum MGS of 45 in each eye. MGS scoring was as follows: 0 = no secretion (worst), 1 = inspissated, 2 = cloudy, 3 = clear liquid (best). A positive change value indicates an improvement.
