Inventor(s): Takeuchi; Satoshi (Torrance, CA)
Assignee:
Application Number:14/464,651
Patent Claims:1. A composition for cleaning contact lenses and producing visible discharge, the composition comprising: polyvinyl-alcohol; povidone; and an isotonic contact solution, comprising a phosphonic compound represented by the formula: ##STR00002## wherein Z is a connecting radical equal in valence to n, wherein n is an integer from 1 to 6, and containing 1 to 12 carbon atoms, and wherein Z is selected from the group consisting of unsubstituted or substituted saturated hydrocarbon radicals and amine-containing radicals, which amine-containing radicals are saturated hydrocarbon radicals in which the carbon atoms are interrupted with at least one nitrogen atom that forms a secondary or tertiary amine and in which the number of carbon atoms in the amine containing radical is at least n+1, wherein said substituted saturated hydrocarbon radicals may be substituted with halogen, hydroxy, amine, carboxy, alkylcarbonyl, alkoxycarbonyl and/or substituted or unsubstituted phenyl, wherein the substituted phenyl may be substituted with halogen, hydroxy, amine, carboxy and/or alkyl, and wherein said alkyl or alkoxy has 1 to 4 carbon atoms, and an effective amount of at least one non-oxidative antimicrobial agent for a contact-lens treating solution.
