1. A method of reducing intraocular pressure comprising:
a) securing a treatment device to an eye, the treatment device comprising a continuous plate structure that enables aqueous humor to flow from a first end to a second end, the first end having a maximum width that is narrower than a maximum width of the second end, the treatment device comprising:
an uppermost surface opposite a lowermost surface, the uppermost surface including a plurality of open cells; and
a fluid pathway including a plurality of open channels formed into the lowermost surface, the plurality of open channels configured in an intersecting grid pattern extending from the first end to the second end,
wherein the treatment device enables aqueous humor to flow along the fluid pathway, thereby reducing intraocular pressure within the eye, and
wherein the first end of the treatment device is inserted into an anterior chamber of the eye and the second end of the treatment device is inserted into at least one of an uveoscleral outflow pathway, Schlemm's canal, a collector channel, a supraciliary space, a trabecular meshwork, a subconjunctival space, or a suprachoroidal space of the eye.
