    摘要: A calibration component for use in calibrating and certifying the accuracy of an ophthalmic wavefront sensor comprises a monolithic, plano-convex refractive optic having known amounts of one or more selected aberrations induced by the spherical, axisymmetric aspherical, or non-axisymmetric aspherical convex surface. An alignment tool is described, along with a procedure for calibrating an aberrometer.

    摘要: An embodiment of the invention is directed to a method for determining an anterior or posterior surface parameter of an ophthalmic correcting surface (e.g., custom contact lens 'CCL,' customized IOL, custom inlay, customized corneal surface) from a wavefront aberration measurement of an eye. A preferred embodiment relates to determining an anterior surface parameter of a dry, CCL designed to operate at 555nm. An algorithm sets forth the method comprising misalignment correction, chromatic aberration correction, and power shift correction due to differences between aberration measurement wavelength and peak vision wavelength, and differences between aberration measurement location and aberration correction location. A device readable medium is the preferable vehicle for the algorithm.

    摘要: An IOL (100), comprising a first diffractive region (110), and a second diffractive region (120) having a power of a different magnitude than the first diffractive region (110), the first region adapted to diffract substantially all light at a first selected wavelength projected therethrough into a single order of diffraction, and the second region adapted to diffract substantially all light at a second selected wavelength projected therethrough into a single order of diffraction.

    摘要: A toric ophthalmic lens having substantially zero spherical aberration for a first circular aperture having a first diameter and substantially zero spherical aberration for a second circular aperture having a second diameter, the first diameter being at least 4 mm and the second diameter being at least 3 mm, the first diameter being at least 0.5 mm larger than the second diameter. A series of ophthalmic lenses, each lens comprising a same spherical power as the other lenses in the set, and a unique cylindrical power, each lens comprising (i) a first toric surface, and (ii) a second surface, at least one of the first surface and the second surface being aspheric in a meridian, the lens having substantially zero spherical aberration for all circular optical zone diameters less than 4 mm.
