advancing a device at least partially through an anterior chamber of an eye and into Schlemm's canal, wherein the device comprises a conduit for delivering viscoelastic fluid to Schlemm's canal;
advancing the conduit along an arc of Schlemm's canal;
delivering about 50 μl of viscoelastic fluid to Schlemm's canal; and
after delivering the about 50 μl of viscoelastic fluid, disrupting trabecular meshwork to improve flow through a trabeculocanalicular outflow pathway.
