Ophthalmic knife and methods of use

An ophthalmic knife, comprising:

• a shaft;
• a first platform connected to an end of the shaft and extending at an angle from a longitudinal axis of the shaft, the first platform comprising:
• a first top surface extending from a first tip;
• a first bottom surface opposing the first top surface;
• and
• first and second sides extending from the first bottom surface to the first top surface and from the first tip laterally toward the shaft, wherein the first and second sides define cutting blades;
• and
• a second platform connected to the shaft adjacent to the first platform, the second platform comprising:
• a second top surface extending from a second tip;
• and
• a second bottom surface opposing the second top surface,
• wherein the first platform is configured to sever trabecular meshwork in a human eye as the trabecular meshwork advances over the first top surface of the first platform, and the second bottom surface of the second platform is configured to engage but not sever the trabecular meshwork.
