The present invention is directed to new and improved packaging systems for storing cationic ophthalmic devices such as cationic contact lenses and to methods for packaging such cationic ophthalmic devices with solutions to improve the comfort of the lenses during wear. In particular, the present invention is directed to a packaging system for storing a cationic ophthalmic device in a solution comprising an effective amount of an anionic polymer. Such solutions are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.
本发明涉及新的和改进的包装系统,用于存储阳离子眼科设备,例如阳离子隐形眼镜,并提供包装这些阳离子眼科设备的方法,以改善佩戴隐形眼镜时的舒适度。具体而言,本发明涉及一种包装系统,用于在包含一定量阴离子聚合物的溶液中存储阳离子眼科设备。这样的溶液可以在未使用的镜片表面保留很长时间,从而导致在眼中持续存在的表面修饰,可能在首次使用的新镜片的润湿性能方面提供显着改善,而且甚至在镜片插入后数小时,也能防止干燥并提高润滑性。
