Abstract

A method of treating dry eye includes delivering light energy from outside an eyelid toward the eyelid, and maintaining the delivery of the light energy toward the eyelid for a period of time sufficient to soften an obstruction of at least one meibomian gland. The light energy may be delivered specifically to the obstruction within the at least one meibomian gland without physically contacting the at least one meibomian gland, or the light energy delivered toward the eyelid may conductively apply heat to the meibomain gland sufficient to melt the obstruction. A corresponding apparatus includes a light energy source positionable outside an eyelid and configured to deliver the light energy from outside an eyelid toward the eyelid, and a controller configured to control the light energy source to maintain the delivery of the light energy toward the eyelid for a period of time sufficient to soften the obstruction.
