Abstract:
Bicomposite intraocular lenses having an anterior surface material different from a posterior surface material are disclosed. The posterior surface material reduces the risk of posterior capsule opacification.
Abstract:
Polyethylene oxide (PEO) coatings providing improved biocompatibility for implantable medical devices are disclosed. The PEO coatings comprise functionalized, end-capped PEO which is attached at one end to the medical device. The PEO compounds are then cross-linked by 1) exposure to a high energy source for a time sufficient to cause the PEO compounds to form a cross-linked, insoluble network or 2) by reacting the free functionalized ends of a sufficient number of bound PEO compounds with a crosslinking agent whose functional groups are reactive toward the bound PEO chain's functionalized ends. These PEO coatings are able to survive ethylene oxide sterilization procedures with minimal loss of protein or cell repulsion ability.
Abstract:
Improved glaucoma filtration device materials comprise at least one monomer having formula (I) wherein X is H or CH3; m is 0-10; Y is nothing, O, or S; R is nothing, H, or an aliphatic, aromatic or aliphatic/aromatic combination of up to twelve carbon atoms, which can be unsubstituted or substituted with Cl, F, Br, or an alkoxy of up to four carbon atoms; and a cross-linking monomer having two or more ethylenically unsaturated groups.
Abstract:
Foldable, acrylic, high refractive index ophthalmic device materials containing a UV absorbing chromophore are cured by exposure to blue light using a benzoylphosphine oxide photoinitiator.
