Efficacy and Safety of Meibomian Gland Dysfunction and Dry Eye With an LED Blue Treatment Device

Not Applicable

Withdrawn

• Conditions: Meibomian Gland Dysfunction
• Interventions: Device: 2-3 Joule LED blue light device

• Registration Number: NCT03788486
• Lead Sponsor: Toyos Clinic

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.

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 Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
2-3 Joule light device for MGD/Dry eye	2-3 Joule LED blue light device	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.

Primary Outcome Measures

Name	Time	Method
change of non invasive tear break up time over the course of the study	one month	3 measurements of non invasive tear break up time by investigator with average recorded

Secondary Outcome Measures

Name	Time	Method
change of number of corneal spk stained with fluorescein over the course of the study	one month	manual counting of number of corneal spk
subjective patient comfort as measured by validated VAS (visual analog scale) dry eye comfort questionnaire	one month	patient completed questionnaire 10 mm in length minimum score 0=no pain and maximal score 100= maximal pain
