简要总结
Clinical Study Evaluating Nordlys™ System with Selective Waveband Technology (SWT)® Intense Pulsed Light (IPL) Applicators for Dry Eye Disease (DED) due to Meibomian Gland Dysfunction (MGD).
详细描述
Subjects will be randomized 1:1 to an experimental study group and a sham comparator (control) group.
Subjects in the experimental group will receive four (4) IPL treatments and meibomian gland expression (MGX) at 2-week intervals. IPL pulses will be administered on the skin of the malar region and below the lower eyelids. Following IPL therapy, subjects will undergo MGX of both eyelids in both eyes. Subjects in the control group will receive the same treatment (IPL followed by MGX), except that the IPL administration will be performed with the device off (sham treatment). Follow-up visits will occur at 1 month and 3 months after the final treatment session. At the follow-up, the changes in the outcome measures will be evaluated and compared between the two groups.

结局指标
主要结局
Improvement of Tear Breakup Time (TBUT) from baseline to 4-week follow-up
时间窗: Baseline, 4-Week Follow Up (Week 10)
The difference in the change of TBUT from Baseline to Follow-Up, between eyes in the study group and eyes in the control group. TBUT is measured in seconds. Improvement is defined as a positive change of TBUT from Baseline to Follow Up. Measurement of TBUT will be implemented using fluorescein ophthalmic strips. Three successive readings will be taken and averaged to a single value.
次要结局
- Difference in change of self-assessed symptoms with the Ocular Surface Disease Index (OSDI) questionnaire, from baseline to follow-up.(Baseline, 1 Month Follow Up at Week 10, and 3 Month Follow Up at Week 18)
- The difference in change of self-assessed symptoms of eye dryness via Eye Dryness Score (EDS) via visual analog scale (VAS), from baseline to follow-up(Baseline, 1 Month Follow Up at Week 10, and 3 Month Follow Up at Week 18)
