  • Patent number: 5505953
    Abstract: Water-soluble borate-polyol complexes are useful as buffers and/or antimicrobials in aqueous ophthalmic compositions, including those containing polyvinyl alcohol. These compositions have greater antimicrobial activity than comparable compositions containing typical borate buffers and unexpectedly increase the antimicrobial efficacy of other antimicrobial agents when used in combination. In addition, use of the borate-polyol complexes avoids the incompatibility problem typically associated with the combination of borate buffer and polyvinyl alcohol; therefore, the compositions disclosed herein may also contain polyvinyl alcohol.

  • Patent number: 5494937
    Abstract: Saline solutions useful in treating contact lenses are described. Unlike prior saline solutions used for similar purposes, the present solutions do not contain conventional antimicrobial agents which are potentially toxic to ocular tissues. Rather, the solutions contain a combination of a borate-polyol complex, one or more anionic or nonionic surfactants, and a low molecular weight amino acid (e.g., glycine). It has been found that this combination effectively preserves the saline solutions from antimicrobial contamination, is relatively nontoxic to ocular tissues, and is compatible with oxidizing agents used in certain contact lens disinfecting systems. The combination also facilitates the cleaning of contact lenses.
