摘要:
The corrector of refraction is described, including but not limited to, intraocular lens (IOLs), contact lenses, corneal inlay and other optical elements or device include a continuous central phase area and periphery phase discontinuity. Further embodiment is related to for being formed this continuous central phase area and periphery phase discontinuity and other application by using the refraction correction device of laser modified refracting characteristic. Refraction correction device and method make Fresnel lens structure include the central area refraction correction device that there is wavefront height to be greater than a design wavelength for continuous phase decelerating area, in the vision application for improving people, while keeping the neighboring area of benefit wrapped phase.
