摘要： Subsurface optical elements are formed within an ophthalmic lens using modulation of depth to which refractive index change inducing laser pulses are focused within the ophthalmic lens. A system for forming one or more subsurface optical structures within an ophthalmic lens comprises a control unit operatively coupled with a laser pulse source and a focusing assembly. The control unit is configured to control operation of the focusing assembly to sequentially focus each of the sequence of laser pulses onto a respective sub-volume of a sequence of sub-volumes of the ophthalmic lens. The sub-volumes of the sequence of sub-volumes have modulated depths within the ophthalmic lens and varying transverse locations within the ophthalmic lens.

摘要： 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.
