An aqueous humor outflow device includes an arcuate scaffold that fits within a conventional aqueous humor outflow pathway of a mammalian eye to receive aqueous humor from a trabecular meshwork of the mammalian eye and allow flow of the aqueous humor through the arcuate scaffold to one or more collector channels that originate in a posterior wall of a Schlemm’s canal. The arcuate scaffold includes a first arcuate rail, and a second arcuate rail spaced apart from, and substantially parallel to, the first arcuate rail. The first and second arcuate rails each have an anterior edge that is adjacent to the trabecular meshwork when inserted in the Schlemm’s canal, and a posterior edge that is adjacent to the posterior wall of the Schlemm’s canal. Structural components coupled to the first arcuate rail and the second arcuate rail maintain the respective anterior and posterior edges of the first and second arcuate rails spaced apart from, and substantially parallel to, each other.
