Excimer laser fiber illumination

A system for performing an intraocular procedure comprising a laser trabeculostomy, the system comprising an excimer laser probe and an excimer laser source, said laser probe comprising:

• a fiber optic core comprising a proximal end couplable to an excimer laser source and a distal end comprising a delivery tip configured to transmit laser energy from said excimer laser source to create transverse channels in a trabecular meshwork of an eye relative to a Schlemm's canal of the eye, wherein:
• the excimer laser source comprises an excimer laser and a gas cartridge,
• the gas cartridge is configured to provide an excimer gain medium to the excimer laser,
• the excimer gain medium comprises a gas mixture comprising a noble gas and a reactive gas, and
• the excimer laser is configured to output ultraviolet light in nanosecond pulses;
• and
• an illumination member for providing illumination in a field of view proximate to said delivery tip of said fiber optic core,
• wherein:
• the delivery tip of the laser probe is angled such that a portion of the delivery tip at a first edge of a circumference of the delivery tip is further away from the proximal end of the fiber optic core than a second edge of the circumference of the delivery tip,
• the first edge and second edge are opposite one another, and
• both of the illumination member and the fiber optic core are angled at the delivery tip.

• and
• an illumination member for receiving an illumination signal from the illumination source and for providing illumination in a field of view proximate to said delivery tip of said fiber optic core,
• wherein:
• the delivery tip of the laser probe comprises an angled surface that forms a plane across an entire diameter of the fiber optic core and the illumination member,
• the fiber optic core is generally cylindrical in shape, and
• the plane is not perpendicular to an axis of the fiber optic core.
