Abstract

A method and apparatus are provided by which eyelid diseases may be treated and eyelid hygiene may be performed. In particular, the method and apparatus stimulate eyelid muscles and facial muscles, allowing stimulation of glandular eyelid components that allow optimization of the tear film and the ocular surface. In this manner, the symptoms associated with ocular irritation or with eyelid disorders may be treated by maintaining proper tear film composition.

Claims

1. A method for treating eyelid disorders, the method comprising:

applying an electrical stimulus to one or more facial muscles associated with one or more eyelid glands; and

promoting the expression of a tear film component from the one or more eyelid glands by application of the stimulus.

2. The method of claim 1, wherein applying the electrical stimulus comprises applying a direct current less than or equal to 1.0 milliamps.

3. The method of claim 1, wherein applying the stimulus to the one or more facial muscles comprises applying the stimulus to one or more periocular muscles.

4. The method of claim 3, wherein applying the stimulus to the one or more periocular muscles comprises applying the stimulus to one or more muscles of Riolan.

5. The method of claim 1, wherein promoting the expression of the tear film component from the one or more eyelid glands comprises promoting the expression of a lipid composition from one or more meibomian glands.

6. The method of claim 1, wherein applying the stimulus comprises:

disposing two or more electrical contacts upon an eyelid; and

applying an electrical current to the eyelid via the two or more electrical contacts.

7. The method of claim 6, wherein the two or more electrical contacts are disposed a fixed distance apart upon an applicator.

8. The method of claim 1, wherein applying the stimulus comprises applying a direct current.

9. The method of claim 1, wherein applying the stimulus comprises applying a direct current having a current density of less than or equal to 2.0 milliamps/cm².

10. The method of claim 1, wherein applying the stimulus comprises applying a direct current having a pulse waveform.
