The present invention provides an improved LbL-coating process for modifying the surface of a medical device, preferably an ophthalmic device, more preferably a contact lens. An LbL coating on a contact lens, which is prepared according to the process of the invention, can have increased hydrophilicity characterized by an averaged contact angle of about 80 degree or less, preferably about 50 degrees or less, while maintaining the desired bulk properties such as oxygen permeability and ion permeability of lens material.
