Embodiment Construction

[0101] The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention and illustrate the best mode of carrying out the invention. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications are within the scope of this disclosure and the appended claims.

[0102] One embodiment of the present invention includes a breakthrough and previously unknown method of applying heat to the inner surface of the eyelid to treat dry eye caused by meibomian gland dysfunction (MGD). Application of heat to the inside of the eyelid is effective and efficient at raising the temperature at the meibomian glands to a temperature sufficient to melt, loosen or soften more severe occlusions or block...

Abstract

Apparatuses, systems, and methods of treating meibomian gland dysfunction. Heat is applied to the patient's eyelid or surrounding tissue to apply heat to the patient's 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 may also be applied to the patient's eyelid or surrounding tissue to improve conductive heat transfer and reduce blood flow in the 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 while reducing the amount of time to reached desired temperature levels and / or aid in reducing discomfort to the patient during treatment.
