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.

Abstract:
Intraocular lenses (300) are provided having a visible-light selective transmissive zone (304, 306) defined therein. The visible light-selective transmissive zone can be located near the lens center and designed to reduce the transmission of any wave-length of visible light specifically light in the blue light region having wavelength between approximately 400 λ to 550 λ.

A polymer material useful for manufacturing an intraocular lens (IOL) suitable for insertion through an IOL inserter barrel having an inner diameter of less than 3 mm is provided. Specifically, acrylic-silicone hybrids having a tensile strength of approximately 100 psi to 400 psi and a percent elongation at break of between 50% and 400% are disclosed.
Abstract:
Described herein are silicone fluids and silicone materials that posses high glass transition temperatures (T g s) when compared to conventional silicone materials. In one embodiment, an increased T g 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.

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 3mm) 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.
