Summary
The aim of the current study is to examine the contribution of intense pulsed light (IPL) for relieving signs and symptoms of dry eye due to meibomian gland dysfunction. The effect of IPL will be examined in a study designed as a randomized controlled trial. In the study arm, subjects will undergo 4 treatment sessions, consisting of IPL pulses immediately followed by meibomian gland expression (MGX). In the control arm, subjects will undergo the same treatments, except that the IPL pulses will be disabled. For each subject, the duration of the study will be 10 weeks, as explained in the detailed description.
