L-HISTIDINE AND VITAMIN B IN OPHTHALMIC SOLUTIONS
An aqueous ophthalmic solution comprising 0.00001 to about 10.0 percent by weight L-histidine, 1 ppm to 60 ppm hydrogen peroxide, 0.00001 to about 10.0 percent by weight of a B vitamin; and 0.1 to 500 parts per million of a preservative that provides superior preservative efficacy especially as against fungal microbes. These solutions may be employed in various ways including cleaning contact lenses, rinsing lenses while in the eye, storing lenses and in delivering active pharmaceutical agents to the eye.
Microporous hydrogels
The invention relates to a porous hydrogel matrix having substantially interconnected tunnel-shaped micropores with a three-dimensional configuration of an interconnected hollow tetrapod network. Such matrices may be used to entrap motile cells that migrate into the micropores of said matrix. The matrices of the invention are formed by a method comprising the steps of providing a solution of a hydrogel-forming material, providing a template material with a three-dimensional configuration corresponding to the negative configuration of the desired interconnected porous structure of the hydrogel material, said template material comprising interconnected zinc oxide tetrapod (t-ZnO) networks, casting the solution of hydrogel-forming material onto the template and removing the template material from the hydrogel material by acid hydrolysis of the template material.

ANTISEPTIC AGENT COMPRISING MEGLUMINE OR SALT THEREOF
The present invention addresses the problem of providing a novel application of meglumine or a salt thereof. The present invention is an antiseptic agent consisting of meglumine or a salt thereof, and a pharmaceutical composition comprising the antiseptic agent according to the present invention, and pertaining to: a pharmaceutical composition which does not comprise benzalkonium chloride and which is placed in a reusable container; a product that comprises the pharmaceutical composition comprising the antiseptic agent according to the present invention and a reusable container; and a method of improving the antiseptic effect of the pharmaceutical composition by comprising meglumine or a salt thereof in the pharmaceutical composition that has been placed in the reusable container.
Ophthalmic contact lens solutions containing forms of vitamin B
The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.
Ophthalmic and contact lens solutions containing simple saccharides as preservative enhancers
The present invention relates to an ophthalmic solution comprising 0.00001 to 10.0 weight percent of a simple saccharide, at least 0.00001 weight percent of a preservative, and not more than about 0.2 percent by weight chloride. The simple saccharide is chosen from the group consisting of: inositol; mannitol; sorbitol; sucrose; dextrose; glycerin; propylene glycol; ribose; triose; tetrose; erythrose; threose; pentose; arabinose; ribulose; xylose; xylulose; lyxose; hexose; allose; altrose; fructose; galactose; glucose; gulose; idose; mannose; sorbose; talose; tagatose; adlose; ketose; heptose; sedoheptulose; monosaccharides; disaccharides; sugar alcohols; xylitol; and polyol.
Electrochemical system for disinfecting and cleaning contact lenses
The present invention is generally related to a lens care system and method for disinfecting and cleaning contact lenses. A lens care system or method of the invention is based on electrolysis of an aqueous chloride solution for generating germicide species (e.g., chlorine, hypochlorous acid, hypochlorite, or combinations thereof) and subsequent in-situ electrolysis of hypochlorous acid or hypochlorite in the aqueous solution for neutralizing the generated germicide species.
