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.
