    摘要: The present invention provides a method for forming on a medical device, preferably an ophthalmic lens, more preferably a contact lens, a diffusion-controllable coating capable of controlling the out-diffusion or release of guest materials from the medical device. The method of the invention comprises: (1) applying one layer of clay and optionally one or more layers of polyionic materials onto the medical device; or (2) applying alternatively a layer of a first polyionic material and a layer of a second polyionic material having charges opposite of the charges of the first polyionic material onto the medical device and releasing the coated medical device into a releasing medium having a composition capable of imparting a desired permeability to the diffusion-controllable coating on the medical device.

    摘要: A method of forming a coating of polyionic materials in a layer-by-layer-like manner onto a polymeric material is provided. A polymeric material, such as a contact lens, can be dipped once into a solution of polyionic materials such that layers of polyionic material can be formed thereon. A single dip solution of the present invention typically contains a polyanionic material and a polycationic material in a non-stoichiometric amount and maintained within a certain pH range.

    摘要: The present invention provides a medical device, preferably an ophthalmic device, more preferably a contact lens, which comprises a lubricious coating including a capping layer of polyvinylpyrrolidone and/or at least one layer of a lubricious coating material and one layer of a polyionic material having charges opposite of the charges of the lubricious coating material. The lubricious coating on the medical device of the invention has increased lubricity, preferably characterized by an averaged CoF of about 3.0 or less, increased hydrophilicity characterized by an averaged contact angle of about 80 degree or less, and increased bacterial adhesion resistance, while maintaining the desired bulk properties such as oxygen permeability and ion permeability of lens material. Such lenses are useful as extended-wear contact lenses. In addition, the invention provides a method for making a medical device, preferably a contact lens, having a lubricious coating thereon.

    摘要: A method of forming a contact lens within a mold is provided. A coating of a polyionic material(s) is applied to the mold before forming a lens therein. The coating can be applied by spraying or dipping the mold within a solution(s) of polyionic materials. Various other additives can also be applied to the mold. The coating can then be transferred to a contact lens formed within the mold such that the resulting lens has altered surface properties.
