    Abstract: The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a water-soluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.

  • Publication number: 20150057389
    Abstract: A wettable hydrogel or a silicone hydrogel device includes a polymerized surfactant incorporated into the gel by addition to a gel, on average, of a single ethylenic functionality of the precursor polymerizable surfactant in the polymerization mixture. The attached polymerized surfactant provides improved lubricity to the hydrogel or silicone hydrogel device. Alternately, a wettable hydrogel or a silicone hydrogel device can be formed by soaking a preformed hydrogel or a silicone hydrogel device in a solution of the polymerizable surfactant and a radical initiator and promoting the polymerization of the polymerizable surfactant and available polymerizable groups on or in the device. The wettable hydrogel or a silicone hydrogel device can be a contact lens.
