Abstract: The present invention provides a method of forming an intraocular lens. First, a chemical vapor deposition (CVD) process is performed to form a first poly-p-xylylene film, following by placing a solution drop on the first poly-p-xylylene film. A chemical vapor deposition encapsulation process is performed to form a second poly-p-xylylene film on the first poly-p-xylylene film and the solution drop.
