| 摘要 |
The present invention provides an aqueous lens care solution for disinfecting and/or cleaning contact lenses in an ozone-based lens care system. The lens care solution of the invention is a hypotonic solution, has an osmolality at about 25° C. of from about 200 mOsm/kg to about 260 mOsm/kg, and comprises at least one relatively-ozone-inert buffering agent selected from the group consisting of boric acid, sodium tetraborate, potassium tetraborate, acetic acid, sodium acetate, potassium acetate, and a mixture thereof. The aqueous lens care solution is compatible with ozone electrolytically generated in an ozone-based lens care system as characterized by comprising about 30 mM or less of chloride ion and less than about 10 mM of one or more ozone-interfering buffering agents. |

1. An aqueous lens care solution for disinfecting and/or cleaning contact lenses in an ozone-based lens care system,
having an osmolality at about 25° C. of from about 150 to about 260 mOsm/kg, preferably from about 170 to about 250 mOsm/kg, more preferably from about 180 to about 240 mOsm/kg, and a conductivity of from about 0.1 mS/cm to about 10 mS/cm, preferably from about 0.5 mS/cm to about 8 mS/cm, more preferably from about 0.5 mS/cm to about 6 mS/cm; and comprising at least one relatively-ozone-inert buffering agent selected from the group consisting of boric acid, sodium tetraborate, potassium tetraborate, acetic acid, sodium acetate, potassium acetate, and a mixture thereof,wherein the aqueous lens care solution is compatible with ozone electrolytically generated in an ozone-based lens care system as characterized by comprising (1) about 30.0 mM/L or less, preferably about 4.0 mM/L or less, more preferably about 2.0 mM/L or less, even more preferably about 0.05 mM/L or less, most preferably about 0.03 mM/L or less of chloride ions and (2) about 10 mM or less, preferably 5 mM or less, more preferably 2 mM or less, even more preferably 1 mM or less of one or more ozone-interfering buffering agents. |
