"Oftalmicamente safe disinfectant solution for a contact lens.Method for disinfecting or cleaning and disinfecting a contact lens soft and kit to disinfect or to disinfect and clean a contact lens.The present invention is directed to a disinfectant solution oftalmicamente safe for contact lenses comprising a bis (biguanide) having formula (I), where R1 and R4 are independently selectsOf the group consisting of branched or not branched alkyl radical having 4 to 12 carbon atoms, or thio ether ether having 4 to 12 carbon atoms.Or cicloalquila or cicloalquil - alkyl radical having 5 to 12 carbon atoms; R2 and R3 are independently selected from the group consisting of hydrogen, alkyl having 1 to 12 carbon atoms.Alcu00f3xialquila having 1 to 12 carbon atoms.Or cicloalquila or cicloalquil - alkyl having 5 to 12 carbon atoms; R6 and R7 are independently selected from the group consisting of hydrogen and alkyl radical having 1 to 6 carbon atoms.And in the above formula is selected from the divalente radical having 4 to 16 carbon atoms consisting of a divalente alkyl, alquilu00f3xialquila, alquilsulfeto,Or a polimetileno interrupted with a radical divalente cyclic.In a configuration of the present invention, such biguanides can be combined with a polymeric biguanide for complementary and synergistic biocidal efficacy.The invention is also directed to an improved method for disinfecting a contact lens.
