1. A device for severing a trabecular meshwork, the device comprising:
a handle;
a shaft;
a platform extending from the shaft, the platform comprising:
a tip at a distal side of the platform;
a bottom surface;
a planar ramp extending from the tip to a proximal side of the platform;
first and second angled sides extending from the bottom surface to the planar ramp and from the tip toward the proximal side of the platform, wherein a width between the first and second angled sides increases toward the proximal side of the platform; and
first and second lateral sides, wherein a portion of the first lateral side defines a first lateral element and a portion of the second lateral side defines a second lateral element,
wherein the planar ramp is configured to elevate a first portion of the trabecular meshwork away from an outer wall of a Schlemm's canal without cutting the first portion of the trabecular meshwork from second portions of the trabecular meshwork and to guide the first portion of the trabecular meshwork to the first and second lateral elements, and
wherein the first and second lateral elements define cutting blades configured to sever the first portion of the trabecular meshwork from the second portions of the trabecular meshwork.
