Claim of US Patent No. 11,110,006


1. A method of reducing intraocular pressure in an eye, the eye having a Schlemm's canal with fluid therein, and one or more collector channels branching from the Schlemm's canal, the method comprising:placing a focus of a laser beam into the Schlemm's canal; and
delivering the laser beam into the Schlemm's canal to initiate a photo-disruptive interaction with the fluid inside the Schlemm's canal to create a pneumatic effect that expands the Schlemm's canal by operating the laser beam with a pulse duration between 10 femtoseconds and 1 nanosecond and a pulse wavelength between 330 nanometers and 2000 nanometers; and
maintaining the focus of the laser beam inside the Schlemm's canal to avoid photo-disruptive interactions with tissue surrounding the Schlemm's canal.
