More Information
Summary: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.
