  • Patent number: 8377126
    Abstract: Disclosed are biomedical devices having a hydrophilic coating on a portion of a surface thereof, the biomedical device comprising: (a) a biomedical device obtained from a polymerization product of a monomeric mixture comprising (i) a polymerizable monomer containing a boronic acid moiety and an electron withdrawing moiety; and (ii) a biomedical device-forming comonomer; and (b) a hydrophilic reactive polymer having complementary reactive functionalities along the polymer chain, wherein the complementary reactive functionalities along the polymer chain of the hydrophilic reactive polymer of (b) bind with the boronic acid moieties of the biomedical device of (a), thereby producing a biocompatible coating which can be removed and re-applied to restore the surface properties of the biomedical device to substantially as-new condition. Methods for treating the biomedical device are also disclosed.

  • Patent number: 8349912
    Abstract: Crosslink agents used to copolymerize at least one hydrophilic monomer with at least one lens monomer typically used to prepare polymeric materials for ophthalmic lenses. The crosslink agents have a relatively high selectivity for the hydrophilic monomer and limited reactivity with the crosslink agent used to polymerize the lens monomer. Accordingly, the invention is also directed to a hydrophilic crosslinked polymer that comprises at least two monomeric units and at least two different crosslink units. The use of the dual crosslink system provides an improved means to control the final chemical, physical and structural characteristics of the resulting polymer.

  • Publication number: 20120329905
    Abstract: An optical copolymer comprising: a constituent derived from a sulfated lens monomer of general formula I [PG-R1—NHC(Y)S—R2]n—R3??I PG is a polymerizable group selected from the group consisting of vinyl, acryloyl, acryoyloxy, methacryoyl and methacryoyloxy; acrylamido and methacrylamido; Y is oxygen or sulfur; and n is 2, 3 or 4. Also, R1 is an organic group of one to eight carbon atoms and optionally with one or more oxygen atoms or an aromatic ring. R2 is a bond or an organic group of one to six carbon atoms. R3 is a bond, an organic group of one to ten carbons atoms, carbon, oxygen, sulfur or a disulfide; and a lens monomer. The sulfated lens monomer is derived from a first component of formula, PG-R1—NC(Y), and a polythiol of formula, R3—[R2—SH]n.

  • Publication number: 20120277342
    Abstract: Novel polymers for biomedical use, especially rigid gas permeable contact lenses that are based on bulky side-chain siloxane cross linkers. The siloxanes, either alone, or as copolymers with bulky and non-bulky mono-functional polymerizable siloxanes, fluoro monomers, such as hexafluoroisopropyl methacrylate, and hydrophilic monomers, result in transparent, high oxygen permeable polymers possessing excellent lathing and milling characteristics.
