Enhanced fiber probes for ELT

1. A system for treatment of glaucoma comprising:

an excimer laser;

a plurality of fiber probes, each fiber probe of the plurality of fiber probes attachable to the excimer laser to treat a subject having glaucoma by delivering shots from the excimer laser;

a display; and

a processor configured to monitor and limit a number of shots delivered by each fiber probe of the plurality of fiber probes, the number of shots delivered by each fiber probe of the plurality of fiber probes programmable by the processor,

wherein the processor is further configured to cause the display to indicate a number of laser shots that have already been fired from a first probe of the plurality of fiber probes while the first probe is connected to the excimer laser.

2. The system of claim 1 , wherein the number of shots is a variable number programmable within a range from a minimum to a maximum.

3. The system of claim 2 , wherein a maximum number of shots is greater than about 10 shots per eye.

4. The system of claim 1 , wherein a delivery tip of each fiber of the plurality of fiber probes comprises an optical fiber jacketed in a metal.

5. The system of claim 4 , wherein the delivery tip is beveled.

6. The system of claim 1 , wherein an interactive user interface is communicatively coupled to the processor for programming each fiber probe of the plurality of fiber probes.

7. A method of treating glaucoma comprising:

programming a fiber probe to deliver a number of shots from an excimer laser source;

inserting the fiber probe into an eye of a subject having glaucoma;

adjusting placement of the fiber probe to a position transverse to the Schlemm's canal in the eye;

applying a plurality of shots from the excimer laser source while the fiber probe is in the position transverse to the Schlemm's canal, thereby treating the glaucoma by creating a plurality of perforations in the Schlemm's canal and/or trabecular meshwork of the eye; and

updating, after each of the plurality of shots is fired, a display to indicate an updated number of laser shots fired by the fiber probe.

8. The method of claim 7 , wherein the number of shots is a variable number programmable within a range from a minimum to a maximum.

9. The method of claim 7 , wherein a maximum number of shots is greater than about 10 shots per eye.

10. The method of claim 7 , wherein a light source aids in adjusting placement of the fiber probe.

11. The method of claim 7 , wherein each perforation of the plurality of perforations has a diameter of about 200 μm.

12. The method of claim 7 , wherein the fiber probe is inserted into an incision in the eye.

13. The method of claim 12 , wherein the incision has a length of about ⅛ inch or smaller.

14. The method of claim 7 , further comprising analyzing effectiveness of at least one shot of the plurality of shots by visualizing drainage of at least one of aqueous humor or bloody reflux.

15. The method of claim 7 , further comprising closing an incision in the eye through which the fiber probe was inserted using one or more sutures.

16. A system for treatment of glaucoma comprising:

an excimer laser;

a plurality of fiber probes, each fiber probe attachable to the excimer laser to treat a subject having glaucoma by delivering shots from the excimer laser;

a display; and

a processor configured to:

cause the display to indicate a number of laser shots that have already been fired from a first probe of the plurality of fiber probes while the first probe is connected to the excimer laser;

cause a subsequent laser shot to be fired from the first probe; and

after the subsequent laser shot is fired from the first probe, cause the display to change to indicate an updated number of laser shots fired by the first probe based on the subsequent laser shot being fired.

17. The system of claim 16 , wherein the system further comprises a user input button configured to receive a user input, wherein the processor is configured to adjust at least one aspect of a laser shot to be delivered by the first probe based on the user input.

18. The system of claim 17 , wherein the at least one aspect of the laser shot is a pulse width of the laser shot.

19. The system of claim 17 , wherein the at least one aspect is an amplitude of the laser shot.

20. The system of claim 16 , wherein the system further comprises a user interface, and wherein the processor is further configured to:

receive a first signal from the user interface based on a first user input, wherein the first signal is indicative of a first user specified number of maximum shots deliverable by the first probe; and

cause the display to show the first user specified number of maximum shots.

21. The system of claim 1 , wherein the processor is further configured to cause, after a subsequent laser shot is fired from the first probe, cause the display to change to indicate an updated number of laser shots fired by the first probe based on the subsequent laser shot being fired.

22. The method of claim 7 , further comprising displaying, on the display, a number of laser shots that have already been fired from the fiber probe while the fiber probe is connected to the excimer laser.

23. A system for treatment of glaucoma comprising:

an excimer laser;

a plurality of fiber probes, each fiber probe attachable to the excimer laser to treat a subject having glaucoma by delivering shots from the excimer laser;

a display; and

a processor configured to:

cause the display to indicate a number of laser shots that have already been fired from a first probe of the plurality of fiber probes while the first probe is connected to the excimer laser.

24. The system of claim 23 , wherein the processor is further configured to, after a laser shot is fired from the first probe, cause the display to change to indicate an updated number of laser shots fired by the first probe based on the laser shot being fired.
