Abstract

A patient interface device adapted to provide an interface between a cornea and a surgical laser system. A frame has an applanation end and an attachment end which is adapted to couple to the surgical laser system. A skirt is affixed to the applanation end of the frame and is adapted to seal against the anterior surface of the cornea to form a chamber. A lens is disposed near the applanation end of the frame and is supported by a flexible support which affixes the lens to the frame.

Claims

1. A patient interface device adapted to provide an interface between a cornea and a surgical laser system, the device comprising:

a frame having an applanation end and an attachment end, wherein the attachment end is adapted to couple to the surgical laser system;

a skirt affixed to the applanation end of the frame, wherein the skirt is adapted to seal against an anterior surface of the cornea to form a chamber;

a lens disposed near the applanation end of the frame; and

a flexible support affixing the lens to the frame.

2. The device of claim 1, wherein the attachment end comprises non-perforated sidewalls.

3. The device of claim 1, wherein the sidewalls form a conical cavity.

4. The device of claim 1, wherein the applanation end of the frame includes a vent port.

5. The device of claim 1, wherein the flexible support comprises a biological barrier.

6. The device of claim 1, wherein the flexible support is annular.

7. The device of claim 6, wherein the lens is centered on the annular flexible support.

8. The device of claim 1, wherein the attachment end is adapted to seal against the surgical laser system.

9. The device of claim 1, wherein the attachment end comprises a ferromagnetic material.

10. The device of claim 1 further comprising a vacuum pump in fluid communication with the chamber.

11. The device of claim 1, wherein the skirt is annular.

12. A patient interface device adapted to provide an interface between a cornea and a surgical laser system, the device comprising:

a frame having an applanation end and an attachment end, wherein the attachment end includes non-perforated sidewalls and the attachment end is adapted to couple to and seal against the surgical laser system;

a skirt affixed to the applanation end of the frame, wherein the skirt is adapted to seal against an anterior surface of the cornea to form a chamber;

a lens disposed near the applanation end of the frame; and

a flexible biological barrier affixing the lens to the frame.

13. The device of claim 12, wherein the sidewalls form a conical cavity.

14. The device of claim 12, wherein the applanation end of the frame includes a vent port.

15. The device of claim 12, wherein the biological barrier is annular.

16. The device of claim 15, wherein the lens is centered upon the annular biological barrier.

17. The device of claim 12, wherein the attachment end includes a ferromagnetic material.

18. The device of claim 12 further comprising a vacuum pump in fluid communication with the chamber.

19. The device of claim 12, wherein the skirt is annular.

20. A patient interface device adapted to provide an interface between a cornea and a surgical laser system, the device comprising:

a frame having an applanation end and an attachment end, wherein the attachment end includes non-perforated sidewalls forming a conical cavity, the attachment end is adapted to couple to and seal against the surgical laser system, and the applanation end includes at least one vent port;

an annular skirt affixed to the applanation end of the frame, wherein the skirt is adapted to seal against an anterior surface of the cornea to form a chamber;

a lens disposed near the applanation end of the frame;

an annular, flexible biological barrier affixing the lens to the frame, wherein the lens is centered upon the biological barrier; and

a vacuum pump in fluid communication with the chamber.

21. The device of claim 20, wherein the attachment end includes a ferromagnetic material.
