1. A method for reducing intraocular pressure of an eye comprising:
advancing a device at least partially through an anterior chamber of the eye and into Schlemm's canal, wherein the device comprises a handle, a fluid reservoir, and a conduit for delivering a volume of viscoelastic fluid to Schlemm's canal;
advancing the conduit along an arc of Schlemm's canal; and
delivering about 8 μl to about 50 μl of viscoelastic fluid to Schlemm's canal to dilate associated collector channels.
