  • Patent number: 10918476
    Abstract: An eye-implantable device including an electrowetting lens is provided that can be operated to control an overall optical power of an eye in which the device is implanted. A lens chamber of the electrowetting lens contains first and second fluids that are immiscible with each other and that differ with respect to refractive index. By applying a voltage to electrodes of the lens, the optical power of the lens can be controlled by affecting the geometry of the interface between the fluids. One of the fluids is an aqueous fluid that is isotonic relative to the aqueous humor of the eye to prevent flux of water into or out of the lens chamber. Thus, the lens chamber may be composed of water-permeable materials. Such water-permeable materials may be flexible, to permit the lens to be folded into a smaller profile during implantation.

    Abstract: A lens for correcting human vision, for example an IOL, contact lens or corneal inlay or onlay, that carries and interior phase or layer comprising a pattern of individual transparent adaptive displacement structures. In the exemplary embodiments, the displacement structures are actuated by shape change polymer that adjusts a shape or other parameter in response to applied energy that in turn displaces a fluid media within the lens that actuates a flexible lens surface. The adaptive optic means of the invention can be used to create highly localized surface corrections in the lens to correct higher order aberrations—which types of surfaces cannot be fabricated into and IOL and then implanted. The system of displacement structures also can provide spherical corrections in the lens.

  • Patent number: 10130461
    Abstract: The new variable power accommodative intraocular lens is comprised by a central body or optical zone that has at least four refracting interfaces that separate different materials. These are connected by means of a substrate that holds them in an equatorial manner, and which includes the bases of the fasteners of the lens embedded in its core. The lens changes its power in response to variations in the equatorial diameter of the materials that comprise the optical zone. Thanks to its design, the lens can achieve variations in the optical powers greater than one diopter per micrometer of equatorial compression. This is achieved through the real change of the curvature radii of the refracting interfaces that comprise the optical zone, as well as the central thicknesses along the length of the optical axis of the different materials that limit said refracting interfaces.

    Abstract: An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics.

A laser flowable blocking element has an enlarged head connected to an extension portion, where a length of the extension portion is more than a distance along the blocking channel from the blocking channel opening to the fluidic connection of the transparent chamber. The extension portion of the laser flowable blocking element is disposed inside the blocking channel. An optical fluid is disposed within the holding chamber under a pressure greater or lesser in comparison to a pressure in the transparent chamber.

  • Patent number: 9226818
    Abstract: An electro-active ophthalmic lens includes an electromyography sensor, a processor, and an electro-active optical element. The electromyography sensor is configured to detect an electric field in a ciliary muscle of the eye that is proportional to a force exerted by the ciliary muscle and to generate a sensor signal indicative of the electric field. The processor is operable to receive the signal from the electromyography sensor and to determine, based on the sensor signal, an adjustment to optical power for an electro-active optical element and to generate a control signal for the electro-active optical element. The electro-active optical element is operable to receive the control signal and to change an optical power of the electro-active optical element in response to the control signal.

  • Patent number: 9186244
    Abstract: An accommodating intraocular lens (IOL) comprises a lens, a flexible surface, and an articulating member joining the lens and the flexible surface. The articulating member comprises first and second arms extending from and joined to form a peripheral portion. The peripheral portion has a length extending radially away from a point at which the first and second arms join together and a thickness that is greater than each of a thickness of the first arm and a thickness of the second arm, first and second arms coupling the lens and the flexible surface, respectively. A flex region is disposed about the second arm and at a distance from the peripheral portion. The flex region permits the flexible surface to articulate relative to the second arm. The flex region has a reduced thickness as compared to each of the second arm and the flexible surface.

  • Patent number: 9072600
    Abstract: A curvature changing accommodative intraocular lens for implantation into the eye of a patient includes a lens body having a base lens which has a base lens power, and a haptic structure including haptic elements projecting from the base lens. An actuator is placed into engagement with the lens body, and includes actuator haptic elements. At least one fluidic optical element is received between the actuator and base lens of the lens body and contains a fluid material therein. During accommodation of the patient's eye, the haptic elements of the lens body and actuator are engaged and apply a force to the fluidic optical element, causing the fluidic optical element to be deformed to generate an additional lens power to adjust the patient's vision.

  • Patent number: RE46615
    Abstract: An implantable, compressible, accommodating intra-ocular lens (IOL) coupled to at least one sensor which detects a signal created by the ciliary muscle. A ciliary sulcus ring can house the at least one sensor, and the sensor can include miniaturized electrodes (ciliary muscle probes) for implanting into the ciliary muscle of the subject. A potentiometer/microcomputer can modulate the ciliary muscle signal detected by the sensor(s) into an electrical signal, and a transmitter sends this electrical signal to a micromotor, which causes compression of the IOL via an annular support ring system, causing a change in the IOL shape. The IOL can be part of an IOL complex including a compressible, accommodating IOL, an external lens membrane, and an annular support ring system. The annular support ring system provides a foundation for the micromotor to compress the IOL.
