Method and apparatus for treating gland dysfunction employing heated medium
First Claim
Patent Images
1. A method of treating dry eye in humans wherein the flow of naturally occurring secretion to the eye is occluded due to the presence of an obstruction of the meibomian gland in the eyelid and comprising the steps of:
- softening the obstruction; and
applying a regulated force to the eyelid to express the obstruction from the meibomian gland.

14. A method of treating dry eye in humans wherein the flow of naturally occurring secretion to the eye is occluded due to the presence of an obstruction in the meibomian gland in the eyelid and comprising the steps of:
-
softening the obstruction by application of thermal energy to the eyelid to heat the obstruction to a temperature of between about 37°
C. to about 47°
C.;
applying a first force to the eyelid;
applying a second pulsatile force to the eyelid while continuing to apply the first force. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method of treating dry eye in humans wherein the flow of naturally occurring secretion to the eye is occluded due to the presence of an obstruction in the meibomian gland in the eyelid and comprising the steps of:
-
softening the obstruction by application of thermal energy to the eyelid to heat the obstruction to a temperature of between about 37°
C. to about 47°
C., the thermal energy being delivered by conduction from a heated medium contained in an expandable bladder applied to the surface of the eyelid;
applying a first force to the eyelid by positioning the bladder proximate the eyelid and selectably expanding the bladder;
applying a second pulsatile force to the eyelid by applying a pulsatile force to the bladder. - View Dependent Claims (24)
