A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the tissue proximate the patient's meibomian glands to provide conductive heat transfer to the meibomian glands, which assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force application device may also apply force to tissue proximate the patient's meibomian glands during the application of heat to improve conductive heat transfer and reduce blood flow in tissue that causes convective heat loss, and to help express obstructions from the meibomian gland, including from a channel of the meibomian gland, with reduced discomfort to the patient. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands.
