Abstract

Controllers for dry eye treatment apparatus and methods are described herein which generally comprise a patch or strip affixed to the skin of the upper and/or lower eyelids to deliver heat to the one or more meibomian glands contained within the underlying skin. The treatment strip or strips include one or more strips configured to adhere to an underlying region of skin in proximity to one or both eyes of a subject such that the one or more strips allow for the subject to blink naturally without restriction from the one or more patches. A controller is in communication with the one or more strips and is programmable to monitor a temperature of the one or more strips to provide a treatment therapy above a threshold temperature of, e.g., 39° C., and below a maximum temperature of, e.g., 48° C., over a treatment period of 12 minutes.

Claims (26)

1. A treatment system comprising:

a first strip attachable to a first eyelid;

a first connector;

a second strip attachable to a second eyelid;

a second connector;

a coupler; and

a controller,

wherein a first end of the first connector extends from the first strip, wherein a second end of the first connector extends from the coupler, wherein a thermal energy is emittable to the first eyelid via the first strip, and wherein the thermal energy emittable to the first eyelid is controllable via the controller,

wherein a first end of the second connector extends from the second strip, wherein a second end of the second connector extends from the coupler, wherein a thermal energy is emittable to the second eyelid via the second strip, and wherein the thermal energy emittable to the second eyelid is controllable via the controller,

wherein the first strip, the first connector, the second strip, the second connector, and the coupler are configured for placement on the same side of a face between a nose and an ear.

2. The treatment system of claim 1 , wherein the first connector comprises a first curve and a second curve.

3. The treatment system of claim 2 , wherein the first curve and the second curve are between the coupler and the first strip, and wherein the first curve and the second curve are between the coupler and the second strip.

4. The treatment system of claim 1 , wherein the coupler is configured to be closer to the first strip and the second strip than to the controller.

5. A treatment system, comprising:

a strip attachable to an eyelid;

a connector;

a coupler; and

a controller,

wherein a first end of the connector extends from the strip, wherein a second end of the connector extends from the coupler, wherein all of the connector is between the strip and an end of the coupler, wherein a thermal energy is emittable to the eyelid via the strip, wherein the thermal energy emittable to the eyelid is controllable via the controller, and wherein the controller is configured to detect a temperature difference between a first region along the strip and a second region along the strip.

6. The treatment system of claim 5 , wherein the thermal energy emittable to the eyelid is adjustable, and/or wherein a treatment time is adjustable.

7. The treatment system of claim 5 , further comprising a connector indicator configured to electronically display when the strip is connected to the controller.

8. The treatment system of claim 1 , wherein the first strip is farther from the coupler than the first connector and the second connector.

9. The treatment system of claim 1 , wherein the second strip is farther from the coupler than the first connector and the second connector.

10. The treatment system of claim 1 , wherein when the first connector and the second connector are between the first strip and the coupler, the thermal energy is emittable to the first eyelid via the first strip and the thermal energy is emittable to the second eyelid via the second strip.

11. The treatment system of claim 5 , wherein the strip comprises a first sensor and a second sensor, and wherein the temperature difference comprises a difference between a temperature detected by the first sensor and a temperature detected by the second sensor.

12. The treatment system of claim 2 , wherein a middle of the first curve and a middle of the second curve are between the coupler and the first strip, and wherein the middle of the first curve and the middle of the second curve are between the coupler and the second strip.
