MULTIFOCAL BIMODULUS CONTACT LENSES
First Claim
1. An ophthalmic lens for correcting presbyopia of an eye, the eye having a cornea characterized by a refractive shape extending across an optical region of the cornea, the ophthalmic lens comprising:
- an inner optic portion and a peripheral portion disposed radially outward of the inner optic portion, wherein,the inner optic portion is configured to be disposed over the optical region of the cornea;
the inner optic portion is characterized by an inner rigidity the peripheral portion is characterized by a peripheral rigidity;
the inner rigidity is greater than the peripheral rigidity; and
the inner rigidity is from about 1E8 MPa-μ
m3 to about 1E11 MPa-μ
m3; and
an anterior surface and a posterior surface opposite the anterior surface, wherein,a portion of the anterior surface is configured to correct presbyopia; and
the posterior surface is configured to provide one or more lenticular volumes between the posterior surface and the optical region of the cornea.

Abstract
Bimodulus multifocal ophthalmic lenses for correcting presbyopia include an inner optic portion characterized by a rigidity greater than a rigidity of an outer peripheral portion. When applied to an eye, the ophthalmic lenses are configured to provide one or more lenticular volumes between the posterior surface of the lens and the cornea. The ophthalmic lenses are further characterized by features on a surface of the lens for improving multifocal visual acuity. The disclosure further relates to methods of correcting presbyopia using the ophthalmic lenses.

20. A method for correcting presbyopia 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 eye so that an inner optic portion of the ophthalmic lens is disposed over the optical region of the cornea, wherein at least a portion of a posterior surface of the positioned ophthalmic lens extends adjacent the eye and is deformed by the eye; and wherein a shape of the posterior surface diverges from the refractive shape of the cornea so that the ophthalmic lens mitigates the presbyopia and mitigates refractive error.
