Abstract

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.

Claims

1. A system for treating meibomian gland disease in at least a portion of an eyelid by a clinician, comprising:

a back plate sized to be positioned between an eyeball and an eyelid of a patient;

a compressive element mechanically linked to the back plate, the compressive element positionable 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 back plate and the compressive element collectively define an aperture between the back plate and the compressive element such that the aperture provides a line of sight that permits viewing of an eyelid margin by the clinician through the aperture when the back plate is positioned between an eyeball and an eyelid of a patient;

a light-emitting device that emits light energy, the light-emitting device positionable outside of the eyelid while the back plate is positioned between the eyeball and the eyelid, wherein the light-emitting device can emit light 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;

a housing, wherein the back plate, the light-emitting device, and the compressive element are mechanically coupled to the housing.

2. The system of claim 1, wherein the compressive element is mechanically linked to the back plate such that the compressive element is slidable along a movement path relative to the eyelid and the back plate when the backplate is positioned between an eyeball and an eyelid of a patient.

3. The system of claim 1, wherein the compressive element can compress a portion of the eyelid without obstructing the clinician'"'"'s view of the eyelid margin adjacent to a compressed eyelid portion when the backplate is positioned between an eyeball and an eyelid of a patient.

4. The system of claim 1, further comprising a magnifying lens coupled to the housing.

5. The system of claim 4, wherein the compressive element, magnifying lens, and the back plate are connected to a single housing.

6. The system of claim 4, wherein the back plate and the magnifying lens are mechanically connected to maintain a fixedly spaced relationship.

7. The system of claim 4, wherein the back plate and the magnifying lens are mechanically connected to maintain an adjustably spaced relationship.

8. The system of claim 4, wherein the compressive element and the magnifying lens are mechanically connected to maintain a fixedly spaced relationship.

9. The system of claim 4, wherein the compressive element and the magnifying lens are mechanically connected to maintain an adjustably spaced relationship.

10. The system of claim 1, further comprising a camera and a display.

11. The system of claim 1, wherein the housing is a handheld housing.

12. The system of claim 1, wherein the back plate is rigidly linked to the housing and the compressive element is movably linked to the housing.

13. The system of claim 1, wherein the compressive element is rigidly linked to the housing and the back plate is movably linked to the housing.

14. The system of claim 1, wherein the both the compressive element and the back plate are movably linked to the housing.
