Abstract

An ophthalmic patient interface system includes an interface device and an ocular device. The interface device includes a frame having a first end and a second end, a lens disposed at the first end, and a skirt affixed to the first end. The second end is adapted to couple with a surgical laser system, and the skirt is adapted to seal against an anterior surface of an eye. The ocular device includes magnifying optics and is adapted to be removably seated within the second end. The magnifying optics image a region on a corneal side of the lens when the ocular device is seated within the second end.

Claims

1. A patient interface system for supporting therapy provided by a surgical laser to an eye, the patient interface system comprising:

an interface device comprising;

a frame having a first end and a second end, wherein the second end is adapted to couple with the surgical laser,

a corneal interface lens disposed at the first end, and

a skirt affixed to the first end, wherein the skirt is adapted to seal against an anterior surface of the eye; and

a centration device comprising;

a first portion adapted to be removably coupled within the second end, the first portion comprising an indicator identifying an optical axis of the interface device when the centration device is coupled to the interface device; and

a second portion contiguous with the first portion, the second portion adapted to secure the first portion to the second end and release the first portion from the second end.

2. The system of claim 1, wherein the interface device further comprises a flexible support affixing the corneal interface lens to the frame, and wherein the flexible support is adapted to displace a pre-determined distance towards the eye when the centration device is seated within the second end, the pre-determined distance based on a pre-applanation of the eye by the corneal interface lens.

3. The system of claim 1, wherein the first portion is adapted to radially bias against an interior surface of the second end when the second portion secures the first portion to the second end.

4. The system of claim 3, wherein the second end of the frame is angled away from the optical axis of the interface device, and wherein the second portion comprises first and second arms, the first and second arms both angled away from the optical axis of the interface device and substantially parallel with the second end of the frame.

5. A system for interfacing a surgical laser with an eye, the surgical laser having an output surface, the system comprising:

a first piece having a first end and a second end, the first end of the first piece adapted to couple to the surgical laser, the second end of the first piece comprising an interface lens contiguous with the output surface when the surgical laser is coupled to the first end of the first piece; and

a second piece having a first end and a second end, the first end of the second piece adapted to receive the second end of the first piece, the second end of the second piece adapted to couple to the eye.
