  • Patent number: 11744697
    Abstract: Disclosed are toric accommodating intraocular lenses. In one embodiment, a toric accommodating intraocular lens comprises an anterior element and a posterior element. The anterior element can comprise an anterior optical surface. The posterior element can comprise a posterior optical surface. A fluid-filled optic fluid chamber can be defined in between the anterior element and the posterior element. The toric accommodating intraocular lens can be configured to correct for corneal astigmatism, spherical aberration, or a combination thereof.

  • Patent number: 11660182
    Abstract: Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.

  • Patent number: 11426270
    Abstract: An intraocular lens is disclosed that includes an optic body with a projection extending radially outwards from a peripheral surface of the optic body. The projection comprises a haptic contact surface facing radially outward, wherein the entire haptic contact surface is a flat surface. A haptic having a free distal end and a proximal portion is secured to the projection along the haptic contact surface, wherein the projection and the proximal portion interface at a butt joint without the haptic extending into the projection and without the projection extending into the haptic. The haptic also includes a haptic fluid chamber.

  • Publication number: 20180256315
    Abstract: Methods of manufacturing an optic of an accommodating intraocular lens to have an aspheric lens surface, including providing an optic comprising an anterior element and a posterior element that at least partially define an optic fluid chamber, wherein at least one of the anterior element and the posterior element has an external surface that is spherical; and prior to inserting the accommodating intraocular lens into an eye, changing the shape of the at least one of the anterior element and the posterior element from the spherical configuration to an aspherical configuration.

  • Patent number: 9918831
    Abstract: Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance.

  • Patent number: 7998198
    Abstract: The present invention is generally directed to accommodative intraocular lenses (IOLs) that exhibit a dynamic spherical aberration as a function of accommodative power. By way of example, in one aspect, the present invention provides an intraocular lens (IOL) having an anterior optical element, a posterior optical element, and a mechanism for coupling the anterior and posterior elements so as to allow axial movement of those elements relative to one another for providing accommodation when the lens is implanted in a patient's eye. Each of the anterior and the posterior elements includes at least one aspherical surface, where the asphericities of the surfaces are adapted to provide a combined spherical aberration that varies with accommodation.
