  • 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.
    Type: Grant

  • 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.

  • Patent number: 7632431
    Abstract: An intraocular lens includes an optic adapted to focus light toward a retina of an eye, and at least one fixation member configured to at least assist in supporting the optic in the eye. The fixation member includes a proximal portion coupled to the optic and a distal portion configured to be in contact with eye tissue when the intraocular lens is in use in the eye. The proximal portion of the fixation member includes at least one first area formed of a first, substantially rigid material, and at least one second area formed of a second material which is more flexible than the first material.

  • Publication number: 20070005135
    Abstract: An intraocular lens (IOL) insertion apparatus for implanting IOLs through smaller incisions. The insertion apparatus includes an insertion cartridge that receives the IOL and cooperates with a handpiece. The cartridge includes a longitudinal lumen from a loading chamber to an open distal mouth that gradually narrows in dimension. A push rod having an extremely soft tip thereon urges the IOL through the cartridge and from the open distal mouth. The soft tip is made of low-stimulus material having a minimum ultimate elongation of 400%. Because of the extremely soft material of the tip, the outside diameter of the open distal mouth can be reduced to no more than 2.0 mm, enabling passage through incisions of 2.2 mm or less. The soft tip may be a thermoplastic elastomer having a relatively high elongation and relatively low modulus at elongations of 100-300%.
