A device, and its production method, the device has a substrate and a coating composition, the coating composition being formed by the gas phase or plasma polymerization of a gas comprising at least one organic compound or monomer. The polymerization is carried out using a pulsed discharge having a duty cycle of less than about &frac15;, in which the pulse-on time is less than about 100 msec and the pulse-off time is less than about 2000 msec. The duty cycle can also be varied, thus the coating composition can be gradient layered accordingly. The device has a coating composition which is uniform in thickness, pin-hole free, optically transparent in the visible region of the magnetic spectrum, permeable to oxygen, abrasive resistant, wettable and biologically non-fouling.

Non-fouling, wettable coated devices

Devices, and their method of production, having coatings deposited by pulsed plasma polymerization of a macrocycle containing a heteroatom, wherein the heteroatom is oxygen, nitrogen, sulfur, or a mixture thereof. The coatings on contact lens are preferably deposited by gas phase polymerization of a cyclic ether, such as crown ether, which coatings are non-fouling and wettable, and the gas phase polymerization utilizes a pulsed discharge.
