1. A cannula for delivering an ocular implant into Schlemm's canal of an eye, comprising:
a curved body member adapted to extend along a medial plane through an anterior chamber of the eye to achieve tangential entry into Schlemm's canal, the body member comprising a lumen configured to direct the ocular implant from a location outside of the eye to a location within Schlemm's canal;
an opening at a distal end of the lumen; and
an asymmetric tip disposed at a distal end of the body member offset from, and asymmetric about, the medial plane, the asymmetric tip being located at an intersection between an upper camming surface and a lower camming surface, the upper camming surface being configured to contact scleral tissue of the eye, and the lower camming surface being configured to contact a scleral spur of the eye to guide the distal end of the body member and at least part of the opening into Schlemm's canal.
