Patent ID: 8534031

Claim:
A method of preparing a package comprising a storable, sterile ophthalmic device, the method comprising: (a) providing an ophthalmic device obtained from a polymerization product of a monomeric mixture comprising (i) a polymerizable monomer containing a boronic acid moiety and an electron withdrawing moiety; and (ii) an ophthalmic device-forming comonomer; (b) immersing the ophthalmic device in an aqueous packaging solution comprising a hydrophilic reactive polymer having complementary reactive functionalities aloneg the polymer chain, wherein the 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 solution and the ophthalmic device in a manner preventing contamination of the device by microorganisms; and (d) sterilizing the packaged solution and ophthalmic device wherein the hydrophilic reactive polymer is a copolymer derived from 2-vinyl-4,4-dimethyl-2-oxazolin-5-one and dimethylacrylamide.
