1. A method of delivering an ocular implant into Schlemm's canal of an eye, the method comprising:
inserting a distal portion of a cannula into an anterior chamber of the eye, the cannula distal portion comprising an opening a beveled edge portion, and a curved trough extending from a proximal extent of the beveled edge portion;
inserting the beveled edge portion into Schlemm's canal;
advancing the ocular implant distally through the cannula into the trough and into Schlemm's canal, wherein the ocular implant is advanced using a delivery tool having a first interlocking portion engaged with a complementary second interlocking portion of a proximal end of the ocular implant;
ceasing advancement of the ocular implant through the cannula when the proximal end of the ocular implant is disposed in the trough;
disengaging the delivery tool from the ocular implant when the proximal end of the ocular implant is positioned in the trough; and
removing the cannula while leaving at least a distal portion of the ocular implant in Schlemm's canal.
