Abstract

Systems for treatment of glaucoma comprise an excimer laser, a plurality of fiber probes, and a processor. Each fiber probe is attachable to the excimer laser to treat a subject having glaucoma by delivering shots from the laser. The processor is configured to monitor and limit a variable number of shots delivered by each fiber probe, the number of shots delivered by each fiber probe programmable within a range. Methods of treating glaucoma include programming a fiber probe to deliver a number of shots from an excimer laser. The fiber probe is inserted into an eye of a subject having glaucoma and adjusted to a position transverse to Schlemm's canal in the eye. A plurality of shots is applied from the excimer laser source while the probe is in the transverse position, thereby treating glaucoma by creating a plurality of perforations in Schlemm's canal and/or the trabecular meshwork.

Claims20

Dependent claims

A method for treating glaucoma comprising:

receiving, at a processor of an excimer laser apparatus, a first signal and a second signal via a user interface based on a first user input and a second user input, respectively, wherein the first signal is indicative of a first user specified number of maximum shots deliverable by a first fiber probe of a plurality of fiber probes and the second signal is indicative of a second user specified number of maximum shots deliverable by a second fiber probe of a plurality of fiber probes, each fiber probe attachable to an excimer laser of the excimer laser apparatus to treat a subject having glaucoma by delivering shots from the excimer laser, wherein each of the shots delivered from the excimer laser comprises pulses of photoablative energy;
causing, by the processor, a display of the excimer laser apparatus to show the first user specified number of maximum shots while the first fiber probe is connected to the excimer laser apparatus or the second user specified number of maximum shots while the second fiber probe is connected to the excimer laser apparatus;
controlling the excimer laser to deliver no more than the first user specified number of maximum shots from the first fiber probe and no more than the second user specified number of maximum shots from the second fiber probe;
monitoring, by the processor, a first number of shots delivered by the first fiber probe and a second number of shots delivered by the second fiber probe;
and
causing, by the processor, the display to show the first number of shots delivered by the first fiber probe or the second number of shots delivered by the second fiber probe.
