    Abstract: Methods and devices are provided to obtain refractive correction with superior visual acuity (e.g., 20/10) by achieving an astigmatism-free customized refractive correction. The astigmatism-free customized refractive correction involves obtaining an objective and precise measurement of cylindrical power in a resolution between 0.01 D and 0.10 D in an eye using an objective aberrometer, reliably relating the cylindrical axis obtained from the objective aberrometer to that in a phoroptor, determining an optimized focus error of an eye through subjective refraction with a phoroptor, generating a customized refraction by combining the objective measured cylindrical power, the objective measured cylindrical axis, and the subjectively measured focus power, fabricating a custom lens with a tolerance finer than 0.09 D based on the generated customized refraction, and delivering an ophthalmic lens that can provide an astigmatism-free refractive correction for an eye.

    Abstract: A method for measuring the optical properties of multifocal ophthalmic lenses. Collimated light is passed through an ophthalmic lens and onto an array of lenslets. Light exiting the array of lenslets is detected by a sensor. Blurred spots and/or double spots may represent diffractive zones of the wavefront. A centroid of the spot or a brighter of two spots may be used to determine the lateral position of the spot. Theoretical calculations, laboratory measurements, clinical measurements and experimental image spots may be generated, compared and cross-checked to determine a monofocal equivalent lens. A Modulation Transfer Function (MTF) may be used to evaluate and compare a diffractive lens and a monofocal equivalent lens.

    Abstract: [Object] A measurement method and an evaluating apparatus are provided which are capable of easily and accurately evaluating the light amount of a spot beam, the diffraction efficiency, and the intensity distribution in the optical axis direction by detecting even a weak diffracted beam in an arbitrary wavelength range converged by a diffraction optical element as an imaging lens.[Means for Attaining the Object] Light emitted from a white light source 11 passes through a wavelength band-pass filter 12 and is diaphragmed by a pinhole slit 13. The resultant light is paralleled by a collimator lens 14 and enters a diffraction optical element 16 as an imaging lens. The light getting out from the diffraction optical element 16 is converged to be a spot beam 17, is magnified by a microscope 18, and is then projected on a CCD 19. A distance changing member 56 changes the distance between the CCD 19 and the diffraction optical element 16, and then, the intensity distribution in the optical axis direction is measured. In-plane intensity distribution perpendicular to the optical axis is also measured.
