Disinfection of contact lenses using bis (biguanides) and polymerized biguanides

摘要

The present invention is directed to an ophthalmically safe disinfecting solution for contact lenses comprising a biguanide polymer in combination with a bis(biguanide), and a method of using the composition, in the form of an aqueous solution, for disinfecting and/or preserving contact lenses, especially soft contact lenses. The invention can be used to formulate products having greater convenience and/or benefits compared to traditional disinfecting products for contact lenses and can provide a broader, more potent and faster antimicrobial activity overall.
