Abstract

Claims (26)

1. A system comprising:

a therapeutic laser for providing a therapeutic laser beam;

a laser delivery conduit coupled to the therapeutic laser;

a determining device for determining a shape and position of a structure of an eye;

a patient interface device (PID) configured to couple to and decouple from the laser delivery conduit and to maintain a constant distance between the determining device and the structure of an eye without attaching to the eye;

a control system comprising a predetermined minimally-invasive glaucoma surgeries (MIGS) procedure laser shot pattern; wherein (i) the determining device for determining the shape and position of the structure of the eye and (ii) the therapeutic laser for providing the therapeutic laser beam are in control communication with the control system; and

a near eye beam directing device comprising a beam director, wherein the near eye beam directing device is physically detached from the PID and the laser delivery conduit, and is configured to:

attach to a surface of the eye to optically couple the beam director with the therapeutic laser to receive the therapeutic laser beam,

maintain the beam director less than 5 mm above the surface of the eye, and

direct the therapeutic laser beam along a directed laser beam path having a beam path angle of greater than 25° relative to an optical axis of the eye; and

wherein, the near eye beam directing device, the control system and the determining device are configured to provide the therapeutic laser beam in the predetermined MIGS procedure laser shot pattern along the directed laser beam path to an area of the eye where an iris and a cornea meet while the PID is the constant distance from the eye and the near eye beam directing device is physically detached from the PID and attached to the eye.

2. The system of claim 1 , wherein the determining device comprises an OCT device.

3. The system of claim 1 , wherein the area of the eye where the iris and the cornea meet comprises one of a drain angle and a trabecular mesh.

4. The system of claim 1 , wherein the beam director comprises a plurality of digital micromirrors (DM).

5. The system of claim 1 , wherein the determining device is configured to provide images of the area of the eye where the iris and the cornea meet along the directed laser beam path.

6. The system of claim 1 , wherein the determining device is configured to determine one or more of the shape and the position of the area where the iris and the cornea meet along the directed laser beam path.

7. The system of claim 1 , wherein:

the near eye beam directing device comprises a suction ring,

the beam director is part of the suction ring, and

the suction ring is configured to couple to the surface of the eye.

8. The system of claim 7 , wherein the near eye beam directing device comprises a handle coupled to the suction ring.

9. The system of claim 1 , wherein the determining device is positioned on the laser delivery conduit.

10. The system of claim 1 , wherein:

the determining device comprises a Scheimpflug device positioned relative to the near eye beam directing device and configured to output a light beam into the near beam directing device, and

the near beam directing device is configured to direct the light beam along a light path coincident with the directed laser beam path and to direct an image beam along an image path coincident with the directed laser beam path back to the Scheimpflug device.

11. The system of claim 1 , further comprising a light illuminating and receiving subsystem positioned relative to the near eye beam directing device and configured to output a light beam into the near beam directing device, wherein the near beam directing device is configured to direct the light beam along a light path coincident with the directed laser beam path and to direct an image beam along an image path coincident with the directed laser beam path back to the light illuminating and receiving subsystem.
