A brush copolymer comprising (a) monomeric units derived from an ethylenically unsaturated boronic acid-containing monomer and (b) a macromonomer having hydrophilic units and boronic acid units.
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 brush copolymers comprising (a) monomeric units derived from an ethylenically unsaturated boronic acid-containing monomer;
- and (b) monomeric units derived from an macromonomer having hydrophilic units and boronic acid units, 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.
