Claim Text:
1. A corneal inlay comprising: an anterior surface configured to reside adjacent a first corneal layer; a posterior surface configured to reside adjacent a second corneal layer; an opening configured to transmit light therethrough, the opening sized to increase depth of focus sufficiently to treat presbyopia in a human patient; an outer zone adapted to substantially prevent transmission of light therethrough, the outer zone having nutrient transport structures disposed therein, the outer zone being configured to provide a peak nutrient flow at locations having nutrient transport structures that are spaced away from an inner periphery of the outer zone compared with locations having nutrient transport structures that are adjacent to the inner periphery of the outer zone; an inner peripheral region disposed between an inner periphery of the corneal inlay and the inner periphery of the outer zone, the inner peripheral region being substantially devoid of holes; an outer peripheral region disposed between an outer periphery of the outer zone and an outer periphery of the corneal inlay, the outer peripheral region being substantially devoid of holes; wherein the outer zone comprises a plurality of annular bands, each of the plurality of annular bands having nutrient transport structures, at least some of the plurality of annular bands having different rates of nutrient transport; and wherein the peak nutrient flow is located in an annular band of the plurality of annular bands that is closer to the inner periphery of the corneal inlay than the outer periphery of the corneal inlay.
