Apparatus for the treatment of glaucoma using visible and infrared ultrashort laser pulses

An apparatus for creating one or more channels in a trabecular meshwork of an eye of a patient to conduct fluid from an anterior chamber into a Schlemm's canal of the eye, the apparatus comprising:

• a femtosecond laser to emit a laser beam comprising a plurality of laser pulses;
• a beam delivery system, comprising:
• a lens;
• a scanner comprising a mirror configured to direct the laser beam from the femtosecond laser through the lens and toward the trabecular meshwork;
• and
• a controller operatively coupled to the femtosecond laser and the beam delivery system, the controller configured to focus and scan the laser beam on a curved surface of a target tissue to create the one or more channels;
• wherein each of the plurality of laser pulses comprises a wavelength of within a range from 0.4 to 2.5 microns, a fluence level to produce optical breakdown, and a pulse duration in a range from 20 femtoseconds to 300 picoseconds.
