A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the inside of the eyelid 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
A system for treating meibomian gland dysfunction comprising a heating element that applies heat to the inside of the eyelid 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. Temperatures at the meibomian glands reach desired higher temperature levels more quickly and efficiently when heating the inside of the eyelid, which may assist in removing obstructions in the meibomian glands. Less time may also be required to reach desired temperature levels when applying heat to the inside of the eyelid. A force application device may also apply force to the patient's eyelid to express the obstruction from the meibomian gland, including from a channel of the meibomian gland, and to increase the temperature level and/or reduce the time to reach desired temperature levels.
