Summary

The aim of the current study is to investigate changes of tear cytokines levels as well as the efficacy and the reduction of demodex infestation after OPT IPL treatment in patients with meibomian gland dysfunction-Associated demodicosis. The effect of OPT IPL will be examined in a study designed as a randomised controlled trial. In the study arm, subjects will undergo 4 treatment sessions, consisting of OPT IPL pulses immediately followed by meibomian gland expression (MGX). In the control arm, subjects will undergo the same treatments, except that the OPT IPL pulses will be disabled. For each subject, the duration of the study will be 2 months , as explained in the detailed description.

Conditions

  • Dry Eye Syndromes

Interventions

DEVICE

OPT IPL

Intense pulsed light (IPL) is a non-invasive and non-laser light treatment that is FDA-approved for various conditions in dermatology. Subjects will receive a total of 4 IPL treatments over the course of the study, at intervals of 2 weeks. Each treatment will include applications of 24 IPL pulses in the malar region and close to the lower eyelids, followed by meibomian gland expression.

DEVICE

Sham OPT IPL

Sham Optimal pulsed technology intense pulsed light IPL will be implemented with an IPL device in which all light is blocked by a filter. Subjects will receive a total of 4 sham treatments over the course of the study, at intervals of 2 weeks. Each treatment will include applications of 24 sham pulses in the malar region and close to the lower eyelids, followed by meibomian gland expression.

PROCEDURE

MGX

Meibomian gland expression (MGX) will be implemented by squeezing the meibomian glands with the aid of stainless steel jaeger lid plate positioned in the inferior fornix space between the tarsal and bulbar conjunctiva, and a cotton swab in another side.
