Abstract

A method of inserting an ocular implant into a patient's eye, the ocular implant being mounted on a carrier, the method comprising: inserting a cannula into an anterior chamber of the eye; moving a distal exit port of the cannula into communication with Schlemm's canal; and advancing the ocular implant and carrier through an exit port of the cannula into Schlemm's canal. The invention also provides an ocular implant and delivery system comprising: a cannula comprising a distal exit port adapted to be inserted into a Schlemm's canal portion of an eye; an ocular implant; a carrier disposed within the implant and movable with the implant within the cannula; and a proximal control adapted to be operated from exterior to an eye to move at least one of the carrier and the implant when the distal exit port of the cannula is within the eye.
