Ophthalmic lenses and related methods employ subsurface optical structures with enhanced refractive index distributions. An ophthalmic lens includes a lens body and a subsurface optical structure within the lens body. Sub-volumes of the optical structure have refractive indexes that vary spatially between a first limit refractive index for the optical structure and a second limit refractive index for the optical structure. The refractive indexes are equal to the first limit refractive index for the optical structure over a first section of the optical structure. The refractive indexes are equal to the second limit refractive index for the optical structure over a second section of the optical structure.

Subsurface optical structure with enhanced distribution of refractive index values

Ophthalmic lenses include one or more annular sectors configured to provide one or more off-axis corrections to light incident on the peripheral retina to inhibit myopia progression. An ophthalmic lens includes a central zone and an annular zone that includes an annular sector configured to provide a myopia inhibiting wavefront correction to light from a peripheral vision region of a peripheral visual field of the use. The first annular sector is configured so that light from the peripheral vision region passes through the first annular sector to form an image of the peripheral vision region on an annular region of the peripheral retina. The myopia inhibiting wavefront correction reduces a circumferential-to-radial aspect ratio of the image of the first peripheral vision region.

Myopia control treatments

Described refractive correctors, include, but are not limited to, intraocular lenses (IOLs), contact lenses, corneal inlays, and other optical components or devices, incorporating a continuous central phase zone and peripheral phase discontinuities. Further embodiments are directed to a method for using a laser to modify the refractive properties of refractive correctors to form such continuous central phase zone and peripheral phase discontinuities, and other applications. The refractive corrector and methods adapt a Fresnel lens structure to include continuous phase retarding regions having a wavefront height of greater than one design wavelength in a central zone of a refractive corrector to improve human vision applications, while maintaining benefits of phase wrapping in the peripheral region.
