Abstract

Corneal implant retaining devices and their methods of use. The retaining devices can be a cap adapted to be disposed over a portion of a corneal implant insertion device.

Claims

1. A corneal implant insertion system, comprising:

a corneal implant insertion device comprising a corneal implant holding area; and

a cap adapted to be disposed over at least a portion of a distal region of the insertion device and adapted to be removed from the distal region of the corneal implant insertion device prior to insertion of a corneal implant, the cap and the insertion device defining a fluid space in which a fluid is maintained,

wherein the cap comprises

a front end that comprises a distal flat face and

an opening passing through the distal flat face, the opening in fluid communication with the fluid space,

wherein the cap has a length less than a length of the corneal implant insertion device, wherein the cap has a proximal end that is disposed distal to a proximal end of the corneal implant insertion device.

2. The system of claim 1 wherein the cap comprises a fluid channel extending therethrough in fluid communication with the opening and the fluid space.

3. The system of claim 1 wherein the cap has a generally cylindrical configuration.

4. The system of claim 3 wherein the distal region of the insertion device has a generally flat configuration.

5. The system of claim 1 wherein the cap includes an inner surface adapted to prevent the corneal implant from escaping the holding area.

6. The system of claim 5 wherein the channel extends from the opening to the inner surface.

7. The system of claim 1 wherein the cap completely surrounds the distal region of the insertion device.

8. The system of claim 1 wherein the holding area is defined by a first surface and a second surface of the insertion device.

9. The system of claim 8 wherein the first and second surfaces are generally flat surfaces.

10. The system of claim 1, wherein the opening is one of a plurality of openings, each of the plurality of openings passing through one of the front end of the cap and the peripheral wall of the cap, each of the plurality of openings being in fluid communication with the fluid space.

11. A corneal implant insertion system, comprising:

a corneal implant insertion device comprising a corneal implant holding area and a distal region with generally flat top and bottom surfaces; and

a cap adapted to be disposed over at least a portion of the distal region of the insertion device and adapted to be removed from the distal region of the corneal implant insertion device prior to insertion of a corneal implant, the cap and the insertion device defining a fluid space in which a fluid is maintained, wherein the cap comprises an opening passing through one of a front end of the cap and a peripheral wall of the cap, the opening in fluid communication with the fluid space,

wherein the cap has a length less than a length of the corneal implant insertion device, wherein the cap has a proximal end that is disposed distal to a proximal end of the corneal implant insertion device.

12. The system of claim 11, wherein the cap comprises a fluid channel extending therethrough in fluid communication with the opening and the fluid space.

13. The system of claim 11, wherein the cap has a generally cylindrical configuration.

14. The system of claim 11, wherein the cap includes an inner surface adapted to prevent the corneal implant from escaping the holding area.

15. The system of claim 11, wherein the cap completely surrounds the distal region of the insertion device.

16. The system of claim 11, wherein the holding area is defined by flat top and bottom surfaces.

17. The system of claim 11, wherein the opening is one of a plurality of openings, each of the plurality of openings passing through one of the front end of the cap and the peripheral wall of the cap, each of the plurality of openings being in fluid communication with the fluid space.
