Intraocular Lens Patents (Class 623/6.11)
  • Patent number: 11045309
    Abstract: Intraocular lenses (IOLs) that improve lens stability by, for example, increasing anterior-posterior stiffness of the IOL, increasing anterior-posterior dimensions of the IOL and/or increasing contact area with the equator of the bag to resist movement of the IOL as the bag collapses over time. These IOLs may be non-modular (single component) or modular (multiple component). In modular embodiments, the IOL system may include intraocular base and optic components, which, when combined, form a modular IOL.

  • Patent number: 10675147
    Abstract: Additive manufacturing techniques are used to form an artificial intra-ocular lens (IOL) directly inside the human eye. Small openings are formed in the cornea and lens capsule of the eye, and the crystalline lens is broken up and removed through the openings; then, a material is injected into the lens capsule through the openings, and the focal spot of a pulse laser beam is scanned in a defined pattern in the lens capsule, to transform the material in the vicinity of the laser focal spot to form the IOL in a layer-by-layer manner. In one embodiment, stereolithography techniques are used where a pulse UV laser source is used to photosolidify a photopolymer resin. The liquefied resin is injected into the eye through the openings, after which only part of the resin, having the shape of the desired IOL, is selectively cured with the UV laser beam, via progressive layer formation.

  • Patent number: 8801781
    Abstract: When fitting a patient for an intraocular lens, a series of measurements is taken on the patient's eye that determines a required lens power. Next, a range of preferred shape factors may be found, which determine the base (i.e., spherical) radii of the two lens surfaces, essentially independent of the lens power. The preferred shape factor adjusts the third-order coma of the lens to largely offset the coma of the cornea, so that the image at the retina has a reduced amount of third-order coma. Once a preferred shape factor is determined, the base radii of curvature of the anterior and posterior surfaces are determined from the shape factor and the lens power by algebraic formulas. Finally, one or more aspheric terms are added to one or both of the surfaces in the lens, so that the spherical aberration of the lens largely offsets the spherical aberration of the cornea.

  • Publication number: 20140152953
    Abstract: The present invention provides a contact lens manufactured at least partially from an intelligent polymer, the lens having a relaxed state which, upon application of a first stimulus forms a first corrective shape and which, upon application of a second stimulus, forms a second corrective shape, wherein the corrective effect provided by the lens in the relaxed state is intermediate to the corrective visual effects provided by the first and second corrective shapes.

  • Patent number: 8740380
    Abstract: An article for use in an OCT method, the article comprising a solid substrate and nanoparticles dispersed in or on the substrate in at least one light transmissive portion of the article such that the nanoparticles result in an increased extinction of the light transmissive portion along a transmission direction of the light transmissive portion compared to the substrate being free of nanoparticles. The extinction of the light transmissive portion along the transmission direction is less than 6, wherein the extinction is defined as a negative decadic logarithm of a ratio of an intensity of light which is transmitted through the light transmissive portion to an intensity of light which is incident on the light transmissive portion, wherein the light is in at least one of a visible and a near infrared wavelength range.

  • Publication number: 20140135916
    Abstract: Disclosed are devices, methods and systems for treatment of eye disease, including open angle glaucoma and narrow angle glaucoma. Implants are described herein that create a directed flow field, such as between the anterior chamber and either the supraciliary space or suprachoroidal space. In addition, the implant can include a variety of features, including extruded features, such as rings and pegs, which can assist in preventing ocular tissue from collapsing onto the implant and occluding fluid pathways.

  • Patent number: 8709078
    Abstract: An improved prosthesis and method for stimulating vision nerves to obtain a vision sensation that is useful for the patient that has lost vision due to age-related macular degeneration (AMD) and retinitis pigmentosa (RP) and other diseases. The present invention utilizes infrared light to cause action potentials in the retinal nerves similar to those which result from rods and cones stimulated by visible light in healthy retinas. In some embodiments, the invention provides a pathway or “image pipe” for transmitting a stimulation pattern of infrared light from an external stimulator array through the eye and focusing the stimulation pattern of infrared light on the retina, especially the fovea. Some embodiments provide improved resolution down to a group of nerves, or even the individual nerve level, with sufficient energy density so as to cause a desired action potential.

  • Patent number: 8696120
    Abstract: The present invention relates to devices, systems and methods for determination or selection of a lens power based on the postoperative vitreous length of an eye. The measurement of VLpre is highly predictive in calculating the postoperative vitreous length, from which the position of the implanted intraocular lens or optic can be derived, and then selection of the appropriate lens power.

  • Publication number: 20140085726
    Abstract: A lens in accordance with the present invention includes an switchable cell consisting of optical substrate with diffraction surface, elastic film in contact with the diffraction surface of the substrate, optical fluid that fills the space between the film and diffraction surface and the mean to transfer the optical fluid in and out of the space between the film and diffraction surface. The refractive index of the optical fluid matches the refractive index of the optical substrate. The switchable cell changes focus positions between refractive focus in relaxed state when the pressure at both sides of the film is the same and diffraction focus when the optical fluid is transported from the space between the film and optical substrate for the film to largely conform to the diffraction surface shape of the optical substrate.

  • Publication number: 20140025165
    Abstract: Provided is a technique which, in the design of intraocular lenses, simplifies design work and makes it possible for aberration of the entire eyeball to more precisely match a target value when the designed intraocular lens is inserted into a patient's eye. This intraocular lens design method involves deriving an intraocular lens aberration target value from the aberration of the cornea and anterior chamber and a set value of the total eyeball aberration (S102), and determining an intraocular lens shape such that the at least the aberration of the intraocular lens coincides with the target value (S103-S107). The intraocular lens aberration is set to an intraocular lens aberration for which prescribed convergent light is incident to the intraocular lens (S104).

  • Patent number: 8632178
    Abstract: In certain embodiments, determining physical lengths of an eye includes determining an optical length of each segment of a plurality of segments of an axis of the eye, where each segment corresponds to a portion of the eye. A refractive index is determined for each segment. A physical length of each segment is determined according to the optical length and the refractive index of the segment.
