Renewable surface treatment of silicone medical devices with reactive hydrophilic polymers

   
   

The present invention is directed toward the renewable surface treatment of medical devices such as contact lenses and medical implants. In particular, the present invention is directed to a method of modifying the surface of a medical device to increase its biocompatibility or hydrophilicity by coating the device with a removable hydrophilic polymer by means of reaction between reactive functionalities on the hydrophilic polymer which functionalities are complementary to reactive functionalities on or near the surface of the medical device. The present invention is also directed to a contact lens or other medical device having such a surface coating.

La actual invención se dirige hacia el tratamiento superficial reanudable de dispositivos médicos tales como lentes de contacto y de implantes médicos. En detalle, la actual invención se dirige a un método de modificar la superficie de un dispositivo médico para aumentar su biocompatibility o hydrophilicity cubriendo el dispositivo con un polímero hidrofílico desprendible por medio de la reacción entre las funcionalidades reactivas en el polímero hidrofílico que las funcionalidades son complementarias a las funcionalidades reactivas encendido o acercan a la superficie del dispositivo médico. La actual invención también se dirige a la lente de contacto o al otro dispositivo médico que tiene una capa tan superficial.
