1. A system for delivering an ocular implant into Schlemm'"'"'s canal through an incision associated with cataract surgery, the system comprising:

  • a cannula defining a central axis and a passageway extending from a proximal end to a distal end along the central axis, the cannula having a distal opening extending through a side wall and the distal end of the cannula to form a trough, a curved distal portion, a curved intermediate portion, and a proximal portion;

    an ocular implant disposed within the passageway of the cannula; and

    a delivery tool having a distal interlocking portion engaging a complementary interlocking portion of the ocular implant; and

    wherein the intermediate portion of the cannula has a first radius of curvature along the central axis and the distal portion has a second radius of curvature along the central axis, the first radius of curvature being greater than the second radius of curvature to allow for substantially tangential entry of the cannula into Schlemm'"'"'s canal through the incision.
