Abstract
An intraocular lens with a hydrophilic polymer coating composition and method of preparing same are provided. Specifically, a composition suitable for reducing tackiness in intraocular lenses is provided wherein an acrylic intraocular lens is treated by vapor deposition with an alkoxy silyl terminated polyethylene glycol polymer composition.
Claims12

- wherein R1, R2 and R3 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.
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.
