Performance of a Translucent Activator for LipiFlow Vectored Thermal Pulse (VTP) Treatment of Meibomian Gland Dysfunction

Abstract

Purpose: Investigator feedback was used to assess the clinical use of the LipiFlow^® System with the new translucent Activator Clear to successfully complete LipiFlow^® treatments.

Patients and methods: This was a prospective, open-label clinical investigation. A total of 88 eyes (44 subjects) were treated using the LipiFlow^® System with the new Activator Clear. Subjects diagnosed with bilateral meibomian gland dysfunction (MGD) were enrolled in the study. Each investigator performed a complete LipiFlow^® treatment with the translucent Activator on both eyes of each subject. Investigators completed a questionnaire assessing the clinical use of the Activator Clear on a 5-point scale (1 - very difficult or strongly disagree, 3 - neutral, 5 - very easy or strongly agree).

Results: The new translucent Activator provided successful LipiFlow^® treatments in 100% of cases, with 95% confidence interval of (96%, 100%). Additionally, the investigators agreed or strongly agreed that the translucent components of the Activator Clear made it easy to access and position the activator with confidence on the subject's eye.

Conclusion: The overall investigators' impressions on usage and functionality of LipiFlow^® System with the translucent Activator were very positive. The Activator Clear enables doctors with efficient and confident positioning around patient eyelids to ensure successful LipiFlow^® treatment when used as indicated.
