Systems and methods for the treatment of eye conditions
Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material.
1. A method of treating meibomian gland disease in at least a portion of an eyelid by a clinician, comprising:
positioning a back plate of a treatment device between an eyeball and an eyelid of a patient;
using the treatment device to heat tissue of the eyelid adjacent to the meibomian glands of the patient to a temperature sufficient to melt or soften meibum of the meibomian glands;
positioning a compressive element of the treatment device adjacent to the outer surface of the eyelid while the back plate of the treatment device is positioned between the eyeball and the eyelid, wherein the compressive element is mechanically linked to the back plate and an aperture exists between the back plate and the compressive element which permits viewing of the eyelid margin by the clinician through the aperture;
applying a compressive force to the eyelid using the compressive element or the back plate;
visually monitoring through the aperture the eyelid margin along the portion of the eyelid being treated while the compression force is being applied;
adjusting treatment to the eyelid while the compressive force is being applied and the eyelid margin is being viewed through the aperture in order to increase an amount of meibum expressed from the orifices.
2. The method of claim 1 , wherein adjusting treatment to the eyelid comprises adjusting an amount of compressive force or an amount of heat applied to the eyelid.
3. The method of claim 1 , wherein adjusting treatment to the eyelid comprises adjusting an amount of compression applied to the eyelid by sliding the compressive element along a movement path relative to the eyelid and the back plate.
4. The method of claim 1 , wherein the compressive element and the back plate are connected to a single housing.
5. The method of claim 1 , wherein the compressive element compresses a portion of the eyelid without obstructing the clinician's view of the eyelid margin adjacent to a compressed eyelid portion.
6. The method of claim 1 , wherein the eyelid margin is visually monitored through a magnifying lens.
7. The method of claim 6 , wherein the compressive element, magnifying lens, and the back plate are connected to a single housing.
8. The method of claim 6 , wherein the back plate and the magnifying lens are mechanically connected to maintain a fixedly spaced relationship.
9. The method of claim 6 , wherein the back plate and the magnifying lens are mechanically connected to maintain an adjustably spaced relationship.
10. The method of claim 6 , wherein the compressive element and the magnifying lens are mechanically connected to maintain a fixedly spaced relationship.
11. The method of claim 6 , wherein the compressive element and the magnifying lens are mechanically connected to maintain an adjustably spaced relationship.
12. The method of claim 6 , wherein the compressive element, magnifying lens, and the back plate are mechanically linked to a handheld housing.
13. The method of claim 1 , wherein the eyelid margin is viewed by the clinician via a camera and a display.
14. The method of claim 1 , wherein the compressive element and the back plate are mechanically linked to a handheld housing.
15. The method of claim 1 , wherein the back plate is rigidly linked to a handheld housing and the compressive element is movably linked to the handheld housing.
16. The method of claim 1 , wherein the compressive element is rigidly linked to a handheld housing and the back plate is movably linked to the handheld housing.
17. The method of claim 1 , wherein the both the compressive element and the back plate are movably linked to a handheld housing.
