Abstract

An apparatus for occluding the upper and lower eyelids of a patient at risk of developing corneal keratopathy. A magnet is attached to or placed within a polymer base that conforms to the normal curvature of the external skin surface of the human eyelid. The conforming base is then attached to the upper eyelid using a removable adhesive such as double-sided tape. A similar conforming base and magnet is attached to the lower eyelid. The magnetic attraction from the opposing magnets pulls the upper and lower eyelids together so as to close the eye, but can be broken by gently spreading apart the conforming bases for examination of the eye or application of medicaments when necessary. Variations of the device can be made where one of the magnets is replaced by a metal plate or other magnetic, or where a pair of electromagnets are used with a control for switching polarity to the electromagnets for reversal between magnetic attractive and repulsive forces and hence opening and closing the eyelids.

Claims

1. An apparatus attachable to the external skin surfaces of upper and lower eyelids for maintaining eyelids in a closed position, comprising:

(a) a first support member for attachment to the external skin surface of a first eyelid;

(b) a second support member for attachment to the external skin surface of a second eyelid opposing said first eyelid;

(c) a magnet carried by said first support member; and

(d) a magnetic material carried by said second support member.

2. An apparatus as recited in claim 1, further comprising adhesive means for detachably coupling said first and second support members to said external skin surfaces of said eyelids.

3. An apparatus as recited in claim 1, wherein said magnetic material carried by said second support member comprises a second magnet.

4. An apparatus as recited in claim 3, wherein opposing poles of said magnets are aligned for magnetic coupling when said support members are attached to said external skin surfaces of said eyelids.

5. An apparatus as recited in claim 1, wherein each said support member comprises an eyelid conforming base having a outer face, and inner face, and a lip projecting outward from said outer face.

6. An apparatus as recited in claim 5, wherein said magnet is attached to said lip of said first support member, and said magnetic material is attached to said lip of said second support member.

7. An apparatus as recited in claim 6, wherein said magnetic material carried by said second support member comprises a second magnet and wherein opposing poles of said magnets are aligned for magnetic coupling when said support members are attached to said external skin surfaces of said eyelids.

8. An apparatus as recited in claim 5, wherein said adhesive means is applied to said inner faces of said eyelid conforming bases.

9. A magnetic eyelid closing apparatus, comprising:

(a) a first eyelid occluder;

(b) a second eyelid occluder;

(c) means for magnetically coupling said first and second eyelid occluders; and

(d) adhesive means for detachably coupling said eyelid occluders to external skin surfaces of eyelids.

10. An apparatus as recited in claim 9, wherein said means for magnetically coupling said first and second eyelid occluders comprises:

(a) a magnet attached to said first eyelid occluder; and

(b) a magnetic material attached to said second eyelid occluder.

11. An apparatus as recited in claim 9, wherein said magnetic material comprises a second magnet.

12. An apparatus as recited in claim 11, wherein opposing poles of said magnets are aligned for magnetic coupling when said eyelid occluders are attached to said external skin surfaces of said eyelids.

13. An apparatus as recited in claim 9, wherein each said eyelid occluder comprises an eyelid conforming base having a outer face, and inner face, and a lip projecting outward from said outer face.

14. An apparatus as recited in claim 13, wherein said magnet is attached to said lip of said first eyelid occluder, and said magnetic material is attached to said lip of said second eyelid occluder.

15. An apparatus as recited in claim 13, wherein said magnetic material carried by said second eyelid occluder comprises a second magnet and wherein opposing poles of said magnets are aligned for magnetic coupling when said eyelid occluders are attached to said external skin surfaces of said eyelids.

16. An apparatus as recited in claim 13, wherein said adhesive means is applied to said inner faces of said eyelid occluders.

17. An eyelid occlusion apparatus for attachment to upper and lower eyelids, comprising:

(a) a first base capable of conforming to the shape of the upper eyelid;

(a) a second base capable of conforming to the shape of the lower eyelid;

(c) a first lip projecting outward from said first base;

(d) a second lip projecting outward from said second base;

(e) a first magnet attached to said first lip; and

(f) a second magnet attached to said second lip;

(g) wherein opposing poles of said magnets are aligned for magnetic coupling when said bases are attached to external skin surfaces of opposing eyelids.
