    摘要: An ophthalmic lens for providing a plurality of foci has an optic comprising an anterior surface, a posterior surface, and an optical axis. The optic has a first region and a second region. The first region has a refractive optical power and comprises a multifocal phase plate for forming a first focus and a second focus. The second region has a refractive optical power and comprises a monofocal phase plate for forming a third focus. The multifocal phase plate and the monofocal phase plate may be disposed on first and second base curvatures, respectively, that may have different radii of curvature. The ophthalmic lens may also have an intermediate phase plate located between the multifocal phase plate and the monofocal phase plate, the intermediate phase plate comprising a third plurality of echelettes disposed on a third base curvature having a third radius of curvature.

    摘要: An ophthalmic lens for providing a plurality of foci includes an optic having an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens has a first region and a second region. The first region has a first refractive optical power and includes a first base curvature having a finite radius of curvature and a first phase plate having at least one diffraction order with a diffractive optical power. The first region is configured for forming a first focus and a second focus. The second region has a second refractive optical power and includes a second base curvature having a finite second radius of curvature that is different from the first radius of curvature and a second phase plate having at least one diffraction order with a diffractive optical power.

    摘要: An ophthalmic lens for providing a plurality of foci has an optic including an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a central phase plate, an intermediate phase plate surrounding the central phase plate, and an outer refractive region. The central phase plate comprises a first base curvature having a first radius of curvature and is configured such that the lens is able to direct light to a first focus and a second focus corresponding different diffraction orders of the phase plate. The intermediate phase plate is configured to change the overall resultant distribution of light directed to the second focus. The outer refractive region has no diffractive optical power and surrounds the intermediate phase plate. The outer refractive region is configured to direct light to the second focus and has an aspheric shape configured to reduce an optical aberration.
