  • SILICONE HYDROGEL LENSES WITH NANO-TEXTURED SURFACES
    Publication number: 20160097939
    Abstract: The invention is related to a method for making a silicone hydrogel contact lens having a nano-textured surface which mimics the surface texture of cornea of human eye. A method of the invention comprises creating a prime coating having nano-textures through controlled imbibition and/or depositions of a reactive polymeric coating material and fixing the nano-textures by crosslinking a hydrophilic polymeric material onto the prime coating to form a crosslinked polymeric coating that preserves the nano-textures of the prime coating and provides a nano-textured surface to the contact lens.
    Type: Application
