    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.

    Abstract: Apparatus, and methods of making and using apparatus, for inserting intraocular lenses (IOLs) are disclosed. The 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.

    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.
