An apparatus having an inserter device with a shaft disposed in an interior space and an intraocular implant adapted to self-retain to an inner wall of Schlemm's canal. The intraocular implant has a proximal portion sized and shaped to reside within an anterior chamber of the eye, the proximal portion having a proximal opening； a distal portion sized and shaped to reside within Schlemm's canal of the eye, the distal portion having a distal opening, and a passageway extending in a straight line from the proximal opening to the distal opening to conduct fluid from the anterior chamber to Schlemm's canal. The shaft of the inserter device is adapted to advance the intraocular implant out of the interior space and through an inner wall of Schlemm's canal.
