Study Overview
Brief Summary
The investigators will be evaluating the use of broadband light in Dry Eye and Meibomian Gland Dysfunction.
Detailed Description
Broadband light (BBL) is a widely used treatment for improvement of inflammatory dermatologic conditions such as acne and rosacea, and may have similar therapeutic benefits on the treatment of dry eye disease by targeting inflammation of the eyelids. The investigators propose a prospective study to determine the safety and efficacy of BBL treatment on patients with dry eye disease and meibomian gland dysfunction. Each participant will have three treatments of BBL at monthly intervals to the cheek and periorbital area with subsequent follow up. Measured endpoints will include signs and symptoms of dry eye control including full ophthalmic exam, dry eye diagnostic testing, photographs, and standardized questionnaires.

- Parallel
- Primary Purpose
- Treatment

Masking Description
Patients will be randomized to protocol 1, 2, or sham but will not be aware of their assignment; investigators grading dry eye at baseline and after treatment will not be aware of which protocol the patients underwent.
