Abstract
Example embodiments include methods for forming a subsurface optical structure in an ophthalmic lens. The method may include defining a phase-wrapped wavefront for causing the ophthalmic lens to diffract light to multiple focal points; defining a spherical wavefront configured for inducing a spherical aberration in the ophthalmic lens; and generating, based on the wavefronts, energy output parameters for forming a subsurface optical structure in the ophthalmic lens using an energy source, wherein the subsurface optical structure is configured to correct presbyopia by providing extended depth of focus that produces increased intermediate vision quality. Also disclosed are ophthalmic lenses with Fresnel rings that effect a phase-wrapped wavefront with a spherical aberration.
