Hydrogen peroxide disinfecting system for contact lenses |
摘要 |
A system and method for disinfecting contact lenses with a stabilized hydrogen peroxide solution and a separate neutralizing solution are described. Sodium stannate (a.k.a. sodium tin oxide) is utilized to stabilize the hydrogen peroxide, and sodium thiosulfate is utilized to neutralize the hydrogen peroxide. In addition to sodium thiosulfate, the neutralizing solution also contains a complexing agent capable of sequestering tin, such as EDTA or EGTA. The system and method provide improvements over prior hydrogen peroxide disinfection systems with respect to stability, predictability and rate of reaction.
