5. The device (10) of claim 4 further comprising a third valve (42a) operatively coupled to the second eyecup (12b) for introducing the fluid into the cavity (18b) of the second eyecup (12b).

6. The device (10) of claim 5 further comprising a fourth valve (42b) operatively coupled to the second eyecup (12b) for venting air from the cavity (18b) of the second eyecup (12b) when the second eyecup (12b) is being filled with the fluid.

7. The device (10) of claim 1 further comprising a sensor (80a) for sensing a temperature of the fluid in the first eyecup (12a).

8. The device (10) of claim 7 further comprising a thermal generator (82a) operatively coupled to the first eyecup (12a) and configured to generate heat so as to increase the temperature of the fluid in the first eyecup (12a).

9. The device (10) of claim 8 further comprising a controller (84) operatively coupled to the sensor (80a) and the thermal generator (82a), the controller (84) configured to receive from the sensor (80a) the temperature of the fluid in the first eyecup (12a) and activate the thermal generator (82a) to increase the temperature of the fluid in the first eyecup (12a) when the temperature drops below a desired temperature.

10. The device (10) of claim 1 further comprising an electrode (66a) in the first eyecup (12a) configured to apply an electrical current to the liquid for a duration sufficient to disrupt and remove debris from the tissue in conjunction with the applied ultrasonic energy.

11. A device (10) for removing debris from tissue of and around an eye including an eyelid margin, the device comprising:

first and second eyecups (12a, 12b), each eyecup (12a, 12b) having an opening (20a, 20b) and a cavity (18a, 18b), wherein each opening (20a, 20b) is of a size and shape sufficient to cover the eye;

first and second valves (40a, 42a), the first valve (40a) operatively coupled to the first eyecup (12a), the second valve (42a) operatively coupled to the second eyecup (12b), each of the first and second valves (40a, 42a) configured to introduce a fluid into each eyecup (12a, 12b);
