摘要： The present invention provides a medical device, preferably a contact lens, which comprises an antimicrobial coating including at least one layer of polyquat of formula (I) or (II). The antimicrobial coating on the medical device of the invention has a high antimicrobial efficacy against microorganisms including Gram-positive and Gram-negative bacterial, a low toxicity, low coefficient of friction, and increased hydrophilicity 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 an antimicrobial coating thereon.

摘要： The present invention provides silicone hydrogel materials having relatively high oxygen permeability and a relatively low modulus. The relatively-low modulus is achieved by adding a chain transfer agent into a polymerizable fluid composition in an amount sufficient to provide to the resultant silicone hydrogel material with a reduced modulus. In addition, the invention provides silicone hydrogel contact lenses comprising a silicone hydrogel material of the invention, a method for making a silicone hydrogel material of the invention, and a method for making a silicone hydrogel contact lens of the invention.
