1. An implant-free method for treating conditions of the eye comprising:
- advancing a conduit via the anterior chamber into Schlemm'"'"'s canal and along an arc of Schlemm'"'"'s canal by actuating a drive assembly in a first direction; and
delivering viscoelastic fluid through the conduit by actuating the drive assembly in a second direction opposite the first direction, wherein the viscoelastic fluid is delivered along the arc of Schlemm'"'"'s canal at a volume sufficient to disrupt the trabeculocanalicular tissues to reduce intraocular pressure.

Abstract
Described here are systems and methods for accessing Schlemm'"'"'s canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm'"'"'s canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

20. A method for reducing intraocular pressure comprising:
-
a) advancing a cannula at least partially through the anterior chamber of the eye, wherein the cannula is connected to a unitary handle having a fluid reservoir located entirely therein; b) entering Schlemm'"'"'s canal at a single access point using the cannula; c) advancing a conduit along an arc of Schlemm'"'"'s canal, and d) operating the handle to deliver a volume of fluid from the fluid reservoir through the conduit along the arc of Schlemm'"'"'s canal, wherein the conduit is slidable within, and extendable from, the cannula, and wherein the volume of delivered fluid is sufficient to disrupt the structure of Schlemm'"'"'s canal and surrounding tissues to reduce intraocular pressure. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 73, 79, 80, 81, 82, 83, 84)

49. A method for treating conditions of the eye comprising:
-
a) entering Schlemm'"'"'s canal via the anterior chamber using a conduit extendable from a unitary handle having a fluid reservoir located entirely therein; b) advancing the conduit along an arc of Schlemm'"'"'s canal; and c) delivering a volume of a viscoelastic fluid from the fluid reservoir through the conduit by decreasing the volume of the fluid reservoir, wherein the volume of delivered viscoelastic fluid is sufficient to disrupt the structure of Schlemm'"'"'s canal and surrounding tissues to reduce intraocular pressure. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 85, 86, 87, 88, 89)
