Abstract
An ocular implant adapted to be disposed within Schlemm's canal of a human eye with a body extending along a curved longitudinal central axis in a curvature plane, a first strut on one side of the implant and a second strut on an opposite side of the implant, the circumferential extent of the first strut with respect to the plane of curvature being greater than the circumferential extent of the second strut with respect to the plane of curvature. The invention also includes methods of using the implant.
Claims8
A method of treating glaucoma in a human eye, the method comprising:
- inserting a cannula through a cornea of the eye into an anterior chamber of the eye;
- placing a distal opening of the cannula in communication with Schlemm's canal of the eye;
- moving an ocular implant out of the cannula through the opening and into Schlemm's canal, the ocular implant comprising a central channel, a central channel opening and first and second landing surfaces on first and second sides of the implant, respectively, the first and second sides being unequal in height, the first and second landing surfaces being disposed on opposite sides of the central channel and the central channel opening, the central channel and the first and second landing surfaces extending longitudinally along Schlemm's canal;
- and
- engaging a scleral wall of Schlemm's canal with the first and second landing surfaces such that reaction forces on the first and second landing surfaces from engagement with the scleral wall as the ocular implant is moving out of the cannula and into Schlemm's canal are substantially equal.
