1. A device for severing a trabecular meshwork, the device comprising:
a shaft;
a platform extending from the shaft, the platform comprising:
a tip configured to pierce the trabecular meshwork;
a bottom surface;
a planar ramp having a single plane extending from the tip to an opposing side of the platform;
first and second angled sides extending from the bottom surface to the planar ramp and from the tip toward the opposing side of the platform; and
first and second lateral sides, extending above the planar ramp,
wherein when the planar ramp is advanced between the trabecular meshwork and an 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 is guided to and severed by top portions of the first and second lateral sides.
