Evaluation of Screening Methods for Treatment of Meibomian Gland Dysfunction

Pilot Study for Evaluation of LipiFlow Screening Methods

The objective is to evaluate the feasibility of using additional screening methods to optimize effectiveness outcomes with the LipiFlow System for application of heat and pressure therapy in adult patients with chronic cystic conditions of the eyelids, including meibomian gland dysfunction, also known as evaporative dry eye or lipid deficiency dry eye, and chalazia. The screening methods include diagnostic expression of the meibomian glands and interferometry assessment of the tear film.
