Abstract: The invention is related to a method of the manufacture of an implantable lens from a liquid polymer precursor in an open mold, during which the liquid polymer precursor in metered into the open mold in a such measured amount, that comes into contact with a functional shaping inner surface of the open mold, which is located under a peripheral circular sharp edge of the stationary open mold or which reaches up to this peripheral circular sharp edge, at which point the open mold, which contains the liquid polymer precursor, is rotated around it's vertical axis at a speed, at which the edge of the surface of the liquid polymer precursor reaches the peripheral circular sharp edge of the open mold, after which the liquid polymer precursor is exposed to conditions, under which it transforms itself into a state of a clear solid polymer by polymerization and/or cross-linking, until such time, at which the stated transition is attained, and then the implantable intraocular lens is removed from the open mold.

Abstract: The present invention is directed to a coating composition which includes a component A and component B. Component A is either an emulsion or dispersion having a hydrophobic elastomer stabilized with at lease one emulsifier. Component B is a dispersion or solution of a hydrophilic polymer which is insoluble in water, swellable in water and soluble in one or more water-miscible solvents. The hydrophobic elastomers may be polymers or copolymers of butadiene, isoprene, chloroprene, styrene, acrylonitrile, ethylene, propylene, isobutylene, alkylacrylates and alkylmethacrylates; polyrethanes, polyureas, polysiloxanes, elastomeric polyamides and polyesters. The hydrophilic polymers may be segmented polyurethanes, segmented polyures, segmented polyesters, partially hydrolyzed poly(vinyl acetate), partially hydrolyzed polyacrylonitrile, partially aminolyzed polyacrylonitrile, and ethylene glycol monomethacrylate.

Abstract: A hydrophilic coating composition used to impart increased lubricity and wettability to the surface of a hydrophobic substrate which is comprised of three essential components:1) Hydrogel-forming polymer component A2) Water-soluble polymer component B3) Common solvent C for the components A and BThe water-insoluble, hydrogel-forming component A consists of a segmented copolymer with long, hydrophilic terminal blocks and the essentially hydrophobic central section. The two polymer components A and B have a limited miscibility in the absence of a common solvent C. Therefore, their blend tends to separate spontaneously into two polymer phases. The phase separation takes place during the solvent evaporation or extraction. A gradient of hydrophilicity and swelling within the coating layer is thus spontaneously created achieving a good adhesion to the substrate and high surface hydrophilicity at the same time.

Abstract: This application describes devices which have a first softer formable state, and the second stiffer shape-retaining shape and which are capable of repeatable transition from the first state to the second state (or vice versa) on demand.

Abstract: There is disclosed novel block copolymers formed of acrylonitrile sequences and sequences containing at least about 50 mole percent of acrylamide units and at most about 50 of units selected from the group consisting of carboxyl, ester, amide, hydrazide and hydroxylamide units and formed by reacting a block copolymer having acrylonitrile sequences and sequences of glutarimide units with a low molecular weight compound having a functional group selected from the group consisting of hydroxyl, primary amino, secondary amino, hydrazo and hydroxylamino group. The reaction is effected at a pH of about 7.5 and higher, preferably in the presence of a solvent and/or swelling agent.
