    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: 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: This invention provides a method for efficiently applying a coating to each of a plurality of objects selected from the group consisting of ophthalmic lenses, molds for making ophthalmic lenses, and other medical devices, the method comprising dipping the plurality of objects into a coating bath containing a coating solution having a coating material; and creating with a means a convective current flow and thereby forcing a coating solution flowing over and under each of the plurality of ophthalmic lenses. In a preferred embodiment, the plurality of objects are held in baskets which are pre-conditioned to have a first layer of polyelectrolytes and a second layer of aqueous solution or have a mixed layer of polyelectrolytes and aqueous solution on the surfaces of the baskets.

    摘要: An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.
