System for providing heat treatment and heat loss reduction for treating meibomian gland dysfunction
First Claim
1. A system for treating meibomian gland dysfunction, comprising:
- a lid warmer containing a heating element, wherein the lid warmer is adapted to be applied to tissue proximate a patient'"'"'s meibomian gland to a temperature level to melt, loosen, or soften an obstruction located within a meibomian gland channel of a meibomian gland;
a force application device positioned on the tissue, wherein the force application device applies a compressive force to the tissue; and
a controller communicatively coupled to the lid warmer and the force application device,wherein the controller is further adapted to;
send a signal to the lid warmer to apply heat to the tissue to a temperature level to melt, loosen, or soften an obstruction located within the meibomian gland channel of a meibomian gland;
control the force application device to generate a compressive force on the tissue to reduce the blood flow in the area of the tissue to reduce thermal dissipation in the tissue and to express the obstruction located within the meibomian gland channel and from within the meibomian gland channel through a meibomian gland orifice of the meibomian gland; and
maintain the signal to the lid warmer to maintain the heat on the tissue for a period of time.

Abstract
A system for treating meibomian gland dysfunction. A controller controls heat applied to the tissue proximate the patient'"'"'s meibomian glands to provide conductive heat transfer to the meibomian glands. The application of heat 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 is also applied 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. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands. Reducing the amount of time to reached desired temperature levels an aid in reducing discomfort to the patient during treatment.
