Abstract: Hydrophilic, arylsiloxy-containing monomers and macromonomers have at least a terminal hydrophilic group attached to an arylsiloxy group. The aryl groups attached to siloxy groups can be substituted with other hydrophilic groups. Polymers comprising such hydrophilic, arylsiloxy-containing monomers and macromonomers avoid or reduce the risk of forming vacuoles of absorbed water. Furthermore, such polymers have high refractive index, and, thus, are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.

Abstract: The use of compositions containing one or more antimicrobial agents with one or more trialkanolamine alkoxylate buffers to disinfect and/or preserve medical devices is described. Solutions containing one or more antimicrobial agents with one or more trialkanolamine alkoxylate buffers and methods of making and using the same are also described.

Abstract: Gas-permeable polymeric materials comprise poly(disubstituted acetylene) and a siloxanyl-based polymer. Medical devices, such as ophthalmic devices, are manufactured from such gas-permeable materials.

Abstract: A hydrophilic, aromatic-based monomer has an aromatic group substituted with at least one hydrophilic substituent and a reactive functional group. Polymers comprising such a hydrophilic, aromatic-based monomers avoid or reduce the risk of forming vacuoles of absorbed water. Furthermore, such polymers have high refractive index, and, thus, are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.

Abstract: Siloxy-containing monomers, macromonomers, or polymers have at least a siloxy-containing side group that comprises a refractive-index increasing substituent. Polymeric compositions comprising such siloxy-containing monomers, macromonomers, or polymers are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.

Abstract: A polysiloxane copolymer that is useful for forming biomedical devices comprises blocks (I) and (II) and is terminated at each end with an ethylenically unsaturated radical: (*Dii*Diol*Dii*PS)x ??(I) (*Dii*PS)y ??(II) wherein: each Dii is independently a diradical residue of a diisocyanate; each Diol is independently a diradical residue of a diol having 1 to 10 carbon atoms; each PS is independently a diradical residue of a polysiloxane-containing diol or diamine; each * is independently —NH—CO—NH—, —NH—COO— or —OCO—NH—: x represents the number of blocks (I) and is at least 2, and y represents the number of blocks (II) and is at least 1.

Abstract: A polymeric material having enhanced oxygen permeability and ion and water transport rates comprises units of a first monomer and a second monomer, which comprises linear poly(ethylene oxide), cyclic poly(ethylene oxide), or combinations thereof. Medical devices, such as ophthalmic devices, are made from such polymeric materials.

Abstract: A copolymer useful as a rigid gas permeable contact lens material is the polymerization product of a monomeric mixture comprising a polysiloxane-containing urethane or urea prepolymer endcapped with polymerizable ethylenically unsaturated radicals.

Abstract: Novel azo-based reactive yellow dyes and a process for manufacturing and using ocular devices having blue light absorption properties. Intraocular lenses so produced block blue light from reaching the retina of an eye implanted with the IOL. By blocking blue light from reaching the retina, the IOL thereby prevents potential damage to the retina.

Abstract: An apparatus for monitoring particulates in a liquid stream and the rate at which the particulates foul a filtering medium, generally a reverse osmosis membrane, to determine at what point in time the filtering medium should be cleaned or replaced. The apparatus includes a monitoring filter unit having a plurality of filter portions. The pressure drop across each filter portion, through which a sample of the feed stream is passed, is monitored. Fouling of a filter portion by accumulated particulate thereon causes an increase in the pressure drop across the filter unit. The increasing pressure drop is monitored as an indicator of the correlative or correspondent fouling of the main filtering medium to be protected. Different filter portions in the filter unit are successively used as each becomes fouled, allowing continuous monitoring for extended periods of time between filter media changes in monitoring filter unit.

Abstract: The present invention discloses an organic compound which assists in minimizing the appearance of or removing unwanted skin growths and discolorations without damaging or scarring the skin. The organic compound of the present invention include a mineral from the family of pyrophyllite and organic apple cider vinegar. The ratio of the bentonite to the vinegar is between about 1:1 to 1:1.5, by weight (grams) to by volume (milliliters). The mineral is preferably bentonite or montmorillonite. A method for making and applying the organic compound is also presently disclosed This method includes a first step of providing a mineral from the family of pyrophyllite. In a second step, organic apple cider vinegar is provided. The mineral is then mixed with the vinegar to form a paste. The paste is then applied to areas of the skin upon which there are growths. Preferably, between about 0.18 to about 0.21 grams of the paste should be applied to about every 0.5 cm of the growth.
