  • Patent number: 10286107
    Abstract: A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.

  • Patent number: 10206773
    Abstract: An accommodating IOL comprises an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the eye to provide effective accommodating movement, preferably axial movement, of the optic. At least a portion of the movement assembly is made from a material that is less stiff and/or more resilient than the material used to make the optic. Optionally, an outer ring or support portion made at least partially from either a relatively stiff material such as the material used in the optic or a relatively resilient material such as the material used in the movement assembly is also provided.

  • Publication number: 20170065405
    Abstract: An intraocular lens for insertion into the capsular bag of an eye contains an optic, an outer periphery, and an outer support structure. The optic has a periphery and centered about an optical axis. The outer periphery is disposed about the optic and configured to engage an equatorial region of the capsular bag of an eye. The outer support structure is disposed along the periphery and spaced from the optic with voids outer support structure and the optic. The intraocular lens further comprises a first intermediate member and a weakened region disposed along the outer periphery between the outer support structure and the first intermediate member. The first intermediate member operably couples the optic and the outer support structure. The weakened region is attached to, and configured to provide relative motion between, the outer support structure and the first intermediate member in response to the ciliary muscle of the eye.

  • Patent number: 9421091
    Abstract: An intraocular lens insertion apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye. A lubricity enhancing component is covalently bonded to the hollow tube at the interior wall in an amount effective to facilitate the passage of the intraocular lens through the hollow space. The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component.

  • Patent number: 9339373
    Abstract: A polymeric material with a molecular response time that makes it suitable for use near fragile body tissues. The polymeric material is useful for both low modulus and high modulus applications thereby simplifying the multi-part polymeric article manufacturing process and creating better integrated multi-part polymeric articles. Cross-linked polymers with different moduli may be obtained utilizing the same or similar starting materials but modifying the amount of catalyst, the amount of cross-linking agent, and/or the amount of methyl vinyl cyclics.

  • Patent number: 8530590
    Abstract: Described herein are silicone fluids and silicone materials that posses high glass transition temperatures (Tgs) when compared to conventional silicone materials. In one embodiment, an increased Tg allows the formation of objects and materials by cryogenic lathing. The fluids and materials can be formed by curing silicone fluid with a cross-linker mixture comprising a cross-linker and a monofunctional hydride compound. Upon formation, the silicone materials can be extracted over long periods of time without loss of optical quality. The silicone materials can be sufficiently soft allowing folding and insertion through small incisions in the eye. Additionally, methods of forming optical silicone materials, lenses and silicone materials in general are also disclosed. In one embodiment, the method of forming a silicone based lens using cryogenic lathing techniques is described.

  • Patent number: 8323799
    Abstract: Soft, flexible highly lubricious coatings for polymeric IOL insertion cartridges that allow IOLs to be easily inserted through small bore cartridges suitable for use with small (less than 3 mm) incisions are provided. These lubricious coatings allow IOLs to be inserted into the eye of a patient without the risk of lens damage or transfer of lubricants to the lens surface during implantation. Specifically, polymeric coatings comprising a matrix polymer having an equivalent weight greater than 5000 g/eq are used to form interpenetrating networks (IPN) on the surface of hydrophobic structural polymers. The IPNs thus formed entrap highly lubricious hydrophilic compounds within the IPN using multi-functional cross linkers.
