  • Patent number: 12213876
    Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.

    Abstract: Systems and methods for creating ophthalmic lens creation instructions are disclosed. The method includes obtaining an ophthalmic prescription and preparing lens creation instructions based on the ophthalmic prescription including determining a baseline lens design. The lens creation instructions are augmented to reduce myopia. The augmented lens creation instructions are created by determining a central region and a peripheral region in the baseline lens, computing a distortion pattern of bumps randomly located in the peripheral region of the lens such that the bumps have random sizes and random strengths, wherein the location, size and strength are created using probability distribution functions, and then computing a final back surface of the lens including incorporating the distortion pattern of bumps into the baseline lens. A lens created by this method is described herein. The method may be implemented on a computing device.

A flexible base substrate is arranged under the container body. Both the container body and flexible base substrate may be made from a soft polymer material and made using low-temperature fabrication processes. The flexible base substrate may be thinner than the container body and provide a relatively large surface area that engages the curved surface such that the stresses associated with wrapping a micro lens assembly onto the curved surface may be primarily absorbed by the flexible base substrate.

  • Patent number: 8777415
    Abstract: Multifocal contact lenses and methods and uses are described. The multifocal contact lenses include an optic zone. The optic zone has an aspheric power profile that provides a near vision refractive power and a distance vision refractive power, and provides an Add power that corresponds to the difference between the near vision refractive power and the distance vision refractive power. The multifocal contact lenses can improve binocular vision of presbyopic subjects by being prescribed such that the non-dominant eye contact lens is over-corrected for distance vision, and both multifocal contact lenses are under-corrected for the Add power requirement of the subject. Batches and sets of multifocal contact lenses are also described.

    Abstract: A method of obtaining an impression of an eye, the method comprises preparing an impression material, contacting the impression material with an eye of a subject, obtaining an impression of the eye on the impression material, creating an indication of the orientation of the impression with respect to the eye, and removing the impression material from the eye. The impression can be used in a method of manufacturing a lens for an eye that comprises receiving one or more data files comprising a back lens surface calculation and a front lens surface calculation, forming a back lens surface from a lens blank based on the back lens surface calculation, forming a front lens surface from the lens blank based on the front lens surface calculation, and forming one or more asymmetric features in the back lens surface based on the back lens surface calculation.

  • Patent number: 8770745
    Abstract: A contact lens or phakic IOC lens is provided with a peripheral portion that has a power profile that provides optical control of peripheral vision images. Typically, the central portion of the lens is also provided with optical control. The power profile of the lens at the boundary of the central and peripheral portions meets certain boundary conditions that ensure that the lens provides a desired or selected vision correction. Because the peripheral portion of the lens provides optical control that defocuses the peripheral vision image relative to the retina, the lens can be used to prevent or inhibit growth of the eye, thereby preventing or inhibiting myopia or the effects of myopia.

  • Publication number: 20140132933
    Abstract: Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than ?6D central refractive error. In one example, a kit or set of lenses (50, FIG. 15) can have multiple parts or sub-sets (52, 54) each comprising a compartmented container (56a, 56b) with lenses (58a, 58b) arranged according to increments of central corrective power (59a, 59b). The lenses (58a) of the first part (52) have four steps (60a, 61a, 62a, 64a) of peripheral power or defocus to provide therapeutic effect and, while the lenses (58b) of the second part (54) also have four steps (60b, 61b, 62b, 64b), the level of therapeutic effect is higher.

  • Patent number: 8721075
    Abstract: A method for determining by optimization a set of progressive ophthalmic lenses for a given user for whom a near vision power addition (Addn) has been prescribed includes the following steps: measuring the user's near vision individual physiological parameters; determining an ergorama associating, on each lens, a target point in each look direction in worn conditions; determining a target power defect and a resulting target astigmatism for each direction of look under worn conditions, the target power defect and the resulting target astigmatism being determined from the user's measured physiological parameters; computing the power required for each lens for said ergorama by successive iterations to reach the target power defect and the target astigmatism for each look direction.

  • Patent number: 8672474
    Abstract: A method and system for treating Presbyopia and pre-Presbyopia are provided that do not compromise the wearer's intermediate or distance vision. The system is a lens and a lens series, wherein the power profiles of the lenses are tailored to provide an amount of positive ADD power in the near vision zone that is slightly less than that which is normally required for near vision accommodation, while also providing an amount of negative spherical aberration in the peripheral optical zone. The dynamic ocular factors of the wearer's eye work in conjunction with the positive ADD power provided by the central optical zone and with the effective ADD gained from the negative spherical aberration provided by the peripheral optical zone to induce a minimally discernible amount of blur that is tuned to maximize the wearer's depth of focus.

    Abstract: A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (an add power). In some embodiments the add power is substantially constant across the inner optic zone. In other embodiments the add power is variable across the inner optic zone. While in some embodiments the inner optic zone has a power designed to substantially eliminate lag of accommodation in the eye with myopia, in other embodiments, the add power may be higher.
