An ocular implant adapted to reside at least partially in a portion of Schlemms canal of an eye. The implant includes a spine extending along a longitudinal axis of the implant, a plurality of curved supports extending from the spine, each support comprising a first end extending from a first location on a first side of the spine and a second end extending from a second location on a second side of the spine, the second location being proximal to the first location, so that each support forms a portion of a helix, the spine and supports defining a volume having a maximum width perpendicular to the longitudinal axis between 0.005 inches and 0.04 inches, the ocular implant being configured to bend preferentially in a preferential bending plane.
