Claim 0:
1. A method of creating one or more openings in a trabecular meshwork of an eye of a patient to conduct fluid from an anterior channel into a Schlemm's canal of the eye, comprising:
ablating a first region to a first depth in the trabecular meshwork with first laser pulses;
ablating a second region to a second depth in the trabecular meshwork with second laser pulses; and
extending the first region with third laser pulses to a third depth and extending the second region with fourth laser pulses to a fourth depth, wherein the first region is extended to the third depth and the second region is extended to the fourth depth after the second region has been extended to the second depth, so as to form a channel between the Schlemm's Canal and the trabecular meshwork, to form the one or more openings to conduct fluid from the anterior channel into the Schlemm's canal;
wherein each of the 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.
