CONTACT LENSES HAVING A REINFORCING SCAFFOLD
First Claim
1. An ophthalmic lens for correcting a refractive error of an eye, whereinthe ophthalmic lens comprising:
- an inner optic portion configured to be disposed over an optical region of the cornea and comprising a center portion configured so that a posterior surface of the inner optic portion is characterized by a shape diverging from a refractive shape of the cornea, wherein the center portion comprises a scaffold; and
a peripheral portion disposed radially outward of the inner optic portion.

Abstract
Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include an inner optic portion having a scaffold between an anterior portion and a posterior portion. The scaffold is characterized by a substantially uniform thickness formed from a material characterized by a modulus that his higher than the modulus of the peripheral portion. Openings within the scaffold are filled with a low modulus material. When applied to an eye, the lenses are configured to provide one or more lenticular volumes between the posterior surface of the lens and the cornea. The disclosure further relates to methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses.

22. A method for correcting a refractive error of an eye, the eye having a cornea with a refractive shape extending across an optical region of the cornea, the method comprising:
-
positioning an ophthalmic lens on the cornea so that an inner optic portion of the ophthalmic lens is disposed over the optical region of the cornea, wherein the ophthalmic lens comprises; an inner optic portion configured to be disposed over the optical region of the cornea and comprising a center portion configured so that a posterior surface of the inner optic portion has a shape diverging from the refractive shape of the cornea, wherein the center portion comprises a scaffold; and a peripheral portion disposed radially outward of the inner optic portion.
