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.
Claims13
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, the first and second landing surfaces being disposed on opposite sides of the central channel opening;
- 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 are substantially equal.
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 extending along a curved longitudinal axis in a curvature plane, the implant comprising a central channel, a central channel opening and first and second landing surfaces disposed on first and second struts disposed on opposite sides of the central channel opening, the first strut extending further out of the curvature plane than the second strut such that the first and second struts are not symmetric about the curvature plane;
- and
- engaging a scleral wall of Schlemm's canal with the first and second landing surfaces during the moving step.
