1. An ophthalmic lens for correcting a refractive error of an eye, the eye comprising a cornea with a refractive shape extending across an optical region of the cornea, the ophthalmic lens comprising:
an inner optic portion configured to be disposed over the optical region of the cornea, wherein the inner optic portion comprises a central portion, an anterior portion disposed anteriorly to the central portion, and a posterior portion disposed posteriorly to the central portion; a posterior surface extending along the inner optic portion adjacent the eye and configured so that engagement of the posterior surface against the cornea deforms the posterior surface and so that the posterior surface has a shape diverging from the refractive shape of the cornea and providing one or more lenticular volumes between the posterior surface and the cornea; an anterior surface extending along the inner optic portion characterized by a spherical profile without a cylindrical component; a peripheral portion of the ophthalmic lens disposed radially outward of the inner optic portion; and a plurality of fenestrations disposed within the inner optic portion, the peripheral portion, or both the inner optic portion and the peripheral portion; and at least some of the plurality of fenestrations are configured to maintain tear fluid within the one or more lenticular volumes between the posterior surface of the inner optic portion and the cornea; wherein the central portion comprises a material characterized by a center modulus from about 20 MPa to about 1500 MPa. |
