Patent ID: 8323723

Claim:
A method for providing an intraocular lens surface with a hydrophilic polymer coating comprising: applying at least one hydrophilic polymer coating to at least one surface of said intraocular lens using vapor deposition, wherein the vapor deposition comprises the steps of: a) exposing a surface of the intraocular lens to an oxygen-comprising plasma in a processing chamber which is at subatmospheric pressure; b) subsequently, without exposure of said oxygen-comprising plasma treated surface to ambient conditions which contaminate or react with said plasma treated surface, exposing said surface to a silicon chloride containing vapor in the presence of moisture, to form a hydrophilic silicon oxide layer on said surface; and c) subsequently, without exposure of said hydrophilic silicon oxide layer to ambient conditions which contaminate or react with said hydrophilic silicon oxide layer, exposing said silicon oxide layer to a polyethylene glycol polymer having a plurality of monomers to form a layer selected from the group consisting of a monolayer, a self-aligned monolayer, and a polymerized cross-linked layer, wherein of the monomers have a structure of Formula 1: wherein R 1 , R 2 and R 3 can be, individually a chlorine or a methoxy group; x is 3; y is an integer from 6 to 9; and R′ is a methoxy.
