The [Q] segment is hydrophilic and has a degree of poly - merization in the range of about 10 to about 10,000. The [A] segment islocated on at least one terminal end of said block copolymer, comprises between about 1 and about 200 repeating units. The block copolymer is associated, via the linear substrate associative segment with surface comprising a at least one hydrophobic site, such as a silicone hydrogel. The polymers may be incorporated into a formulation from which the silicone hydrogel is made or may be contacted with the silicone hydrogel post-formation.
