ELECTROLYTIC DEVICE FOR TREATING AN EYE DISORDER
Devices and methods are described for electrolytically, ultrasonically, or both electrolytically and ultrasonically disrupting debris on an eyelid margin. A method contacts debris on an eyelid margin with a first electrode and contacting a surface of an eyelid with a second electrode and supplying electrical energy to one of the first or second electrodes to disrupt the debris on the eyelid margin. Another method applies ultrasonic energy to the eyelid margin to disrupt debris on the eyelid margin. In yet another method electrical energy is supplied to a structure within the eyelid to disrupt debris within that structure while not harming the underlying the eyelid margin, the eyelid, or the structure within the eyelid.
1 . A method of disrupting debris within a structure within an eyelid comprising:
providing a device with an eye contacting portion with a surface, the surface having a first electrode and a second electrode;
contacting an eyelid margin with the first electrode;
contacting a surface of an eyelid adjacent to but spaced apart from the eyelid margin with a second electrode; and
supplying electrical energy to one of the first or second electrodes in an amount sufficient to disrupt debris within a structure within the eyelid while not harming the underlying the eyelid margin, the eyelid, or the structure within the eyelid.
2 . The method of claim 1 , wherein the structure within the eyelid is at least one meibomian gland.
3 . The method of claim 1 , wherein the structure within the eyelid is at least one eyelash follicle.
4 . The method of claim 1 , wherein the structure within the eyelid is at least one lacrimal gland.
5 . The method of claim 1 , further comprising:
expressing the debris out of the structure within the eyelid; and
supplying a wash solution to remove debris disrupted by the electrical energy and expressed from the structure within the eyelid.
6 . The method of claim 1 , wherein the electrical energy has a voltage between about 0.1 volts and 20 volts.
7 . The method of claim 1 , wherein the electrical energy has a current of less than about 3 milliamps.
8 . The method of claim 1 , further comprising contacting the eye with an eye contacting portion and applying ultrasonic energy to the eyelid via eye contacting portion.
9 . A method of disrupting debris within a structure within an eyelid comprising:
providing a device with an eye contacting portion with a surface, the surface having a first electrode and a second electrode;
contacting a portion of an eyelid across at least fifty percent of the width of the eyelid with the eyelid contacting portion;
applying ultrasonic energy to the portion of the eyelid via the eyelid contacting portion, and
disrupting, with the ultrasonic energy, debris within a structure within the eyelid.
10 . The method of claim 9 , wherein the structure within the eyelid is at least one meibomian gland.
11 . The method of claim 9 , wherein the structure within the eyelid is at least one eyelash follicle.
12 . The method of claim 9 , wherein the structure within the eyelid is at least one lacrimal gland.
13 . The method of claim 9 , wherein the portion of the eyelid is selected from the group consisting of external portion of an upper eyelid, an external portion of a lower eyelid, a upper eyelid margin between the external surface of the upper eyelid and an internal surface of the upper eyelid, a lower eyelid margin between the external surface of the lower eyelid and an internal surface of the lower eyelid, the internal surface of the upper eyelid, the internal surface of the lower eyelid, or combinations thereof.
