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.
