The investigators have previously studied the effect of the BlephEx instrument (debridement of lid debris) in relieving signs and symptoms of blepharitis (Connor CG et al, ARVO 2014). This previous study demonstrated positive results from the BlephEx treatment. Warming the eyelids (e.g., using warm wash cloths) still remains a viable treatment option for this disease. However, patients are often non-compliant with warm compress therapy due to the requirement of performing it at least twice per day. The MiBoflo delivers uniform and consistent amounts of heat to the eyelid. It is suggested that two treatments over 30 days is adequate to relieve signs and symptoms of Meibomian gland dysfunction. This equipment is currently used in optometric practices in this country.
