Claim 13:
14. A device for severing a trabecular meshwork, the device comprising:
a handle;
a shaft extending along a longitudinal axis;
a platform extending from the shaft for elevating a portion of the trabecular meshwork away from an outer wall of Schlemm's canal, the platform comprising:
a tip at a distal side of the platform configured to pierce the trabecular meshwork;
a bottom surface;
a planar ramp having a single plane extending from the distal side to a proximal side of the platform opposite the distal side;
a right edge and a left edge extending towards the proximal side of the platform from the tip, the right edge and the left edge extending upwards from the bottom surface, where the right edge and the left edge have a first height at the tip and a second height near the proximal side of the platform, the second height being greater than the first height;

wherein when the planar ramp is advanced between the trabecular meshwork and the outer wall of Schlemm's canal, a portion of the trabecular meshwork on the planar ramp is elevated away from the outer wall of the Schlemm's canal without cutting the portion of the trabecular meshwork from surrounding portions of the trabecular meshwork and the portion of the trabecular meshwork is guided to the right and left edges; and
wherein top portions of the right and left edges extending away from the bottom surface are configured to sever trabecular meshwork tissue as the trabecular meshwork tissue advances in a rearward direction over the platform.
