Abstract
A packaging system for the storage of an ophthalmic device is disclosed. The packaging system comprises a sealed container containing one or more unused ophthalmic devices immersed in an aqueous packaging solution comprising one or more hydrophilic polymers or copolymers comprising hydrophilic units and endcapped with a hydrophobic end group and a hydrophilic end group, wherein the solution has an osmolality of at least about 200 mOsm/kg, a pH of about 6 to about 9 and is heat sterilized.
Claims28
A packaging system for the storage of an ophthalmic device comprising a sealed container containing one or more unused ophthalmic devices immersed in an aqueous packaging solution comprising one or more hydrophilic polymers or copolymers comprising hydrophilic units, the one or more hydrophilic polymers or copolymers having a hydrophobic terminal end group and a hydrophilic terminal end group, wherein the aqueous packaging solution has an osmolality of at least about 200 mOsm/kg, a pH of about 6 to about 9 and is heat sterilized.
A method of preparing a packaging system comprising a storable, sterile ophthalmic device, the method comprising:
- (a) providing an ophthalmic device;
- (b) immersing the ophthalmic device in an aqueous packaging solution comprising one or more hydrophilic polymers or copolymers comprising hydrophilic units, the one or more hydrophilic polymers or copolymers having a hydrophobic terminal end group and a hydrophilic terminal end group, wherein the aqueous packaging solution has an osmolality of at least about 200 mOsm/kg and a pH in the range of about 6 to about 9;
- (c) packaging the aqueous packaging solution and the ophthalmic device in a manner preventing contamination of the ophthalmic device by microorganisms;
- and
- (d) sterilizing the packaged solution and the ophthalmic device.
