  • Publication number: 20180136487
    Abstract: The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.

  • Publication number: 20170336653
    Abstract: A corrective lens system for the eyes of an individual includes first and second pairs of lenses of first and second prescriptions, respectively. In certain embodiments, the first pair of lenses includes a first lens for the left eye and a first lens for the right eye, and the second pair of lenses includes a second lens for the left eye and a second lens for the right eye. The first and second pairs of lenses may be configured in package having a plurality of compartments with individual lenses disposed in individual compartments. A set of instructions may be provided for wearing the first pair of lenses for a first time period and the second pair of lenses for a second time period. The first prescription is different from the second prescription. The lenses may inhibit the progression of myopia in the individual. Methods of arranging, prescribing, and using the lens system are described.

  • Publication number: 20170322110
    Abstract: A method for assessing the similarity between a power profile of a manufactured optic device and a nominal power profile upon which the power profile of the manufactured optic device is based. The method comprises measuring the power profile of manufactured optic device, identifying a region of interest from the measured power profile of manufactured optic device, and applying an offset to the measured power profile to substantially minimize a statistical quantifier for quantifying the similarity between the nominal power profile and the offset measured power profile. The method further comprises comparing the offset and the statistical quantifier to predefined quality control metrics, determining whether the measured power profile meets the predefined quality control metrics based, at least in part on the comparison.

  • Publication number: 20170115508
    Abstract: Certain embodiments are directed to lenses, devices and/or methods. For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0). The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 0.35, the second RIQ is at least 0.1 and the through focus range is at least 1.8 Diopters; (ii) a RIQ of 0.3 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 0.3 with a through focus slope that degrades in a direction of eye growth.

  • Patent number: 8814356
    Abstract: An optically realistic model eye is described. The optically realistic eye model has an optical axis and includes: an anterior replaceable module comprising a model cornea, model iris and model lens rotatably mounted for rotation about said axis, said module being representative of an emmetropic or pathological natural eye; an enclosure located posterior to said module and adapted to enclose a retinal area within which an image of an external object is brought to focus by said module; and a photoactive device movable within said enclosure and retinal area and adapted to detect or reflect a portion of the image for inspection, processing or analysis.
