| titleOfInvention | Contact lens packaging solutions |
| abstract | An ophthalmic product, comprising a sealed and sterilized package which include a packaging solution and a soft hydrogel contact lens immersed in the packaging solution, wherein the packaging solution includes: a homopolymer or copolymer of vinylpyrrolidone, wherein the homopolymer or copolymer of vinylpyrrolidone is present in an amount sufficient to provide the packaging solution a viscosity of up to about 5.0 centipoises at 25°C; glycerin or a polyethylene glycol having an average molecular weight of about 600 or less; an .alpha.-oxo-multi-acid or salt thereof in an amount sufficient to have a reduced susceptibility to oxidation degradation of the polyethylene glycol in the packaging solution; and one or more buffering agents in an amount sufficient to provide the solution a pH of from about 6.0 to 8.0, wherein the packaging solution has an osmolality of from about 200 to about 450 mOsm/kg. The application further provides a process for making a soft contact lens. |
