Brief Summary:
This study will test the efficacy and safety of application of LED light to meibomian glands in upper and lower eyelids in eyes of patients suffering with meibomian gland disease.

Condition or disease Intervention/treatment Phase
Meibomian Gland Dysfunction Device: 2-3 Joule LED blue light device Not Applicable

Detailed Description:

This study will test the efficacy and safety of application of LED light to meibomian glands in upper and lower eyelids in eyes of patients suffering with meibomian gland disease.

The primary objective of the study is to investigate the safety and efficacy of blue LED light with meibomian gland expression of the upper and lower eyelids in dry eye disease by change from baseline in subjective questionnaire and by measurement of non-invasive tear break up time.

Primary Endpoint: Improvement of tear break up time over the length of the study

Secondary endpoint: subjective patient comfort over the length of the study using a validated dry eye comfort questionnaire administered at each study visit, VAS, 0= no pain and 100 = maximal discomfort, Improvement in the number of corneal SPK that stain with fluorescein.

20 study subjects 18-85 will be enrolled with male or female in the Nashville and Memphis, TN areas who are generally healthy but have signs and symptoms of dry eye disease with Meibomian gland dysfunction.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Intervention Model: Single Group Assignment
Intervention Model Description: Single site prospective study with no control group to assess the safety and clinical efficacy of a low power LED light device on the signs and symptoms of dry eye disease.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 4 Study to Assess the Clinical Efficacy and Safety of Meibomian Gland Dysfunction and Dry Eye With an LED Blue Light Treatment Device
Actual Study Start Date : February 12, 2019
Estimated Primary Completion Date : June 1, 2020
Estimated Study Completion Date : August 1, 2020

Arm Intervention/treatment
Experimental: 2-3 Joule light device for MGD/Dry eye
patients who qualify for the study will receive interventional in office treatments with the light treatment device in the upper and lower lids for defined periods of time twice weekly for a total of one month. Non-invasive tear break up, subjective questionnaires and corneal fluorescein staining will be measured through the course of the study.
Device: 2-3 Joule LED blue light device
application of blue light LED light device for 2 minutes in the central lower lids, temporal lower lids and upper temporal lids twice weekly under observation for one month

Primary Outcome Measures :
  1. change of non invasive tear break up time over the course of the study [ Time Frame: one month ]
    3 measurements of non invasive tear break up time by investigator with average recorded

Secondary Outcome Measures :
  1. subjective patient comfort as measured by validated VAS (visual analog scale) dry eye comfort questionnaire [ Time Frame: one month ]
    patient completed questionnaire 10 mm in length minimum score 0=no pain and maximal score 100= maximal pain

  2. change of number of corneal spk stained with fluorescein over the course of the study [ Time Frame: one month ]
    manual counting of number of corneal spk
