Patent number: 12276869Abstract: A WS12-releasing contact lens is described as well as method of manufacturing the same. The WS12-releasing contact lens comprises a polymeric lens body and WS12 releasably adhered to the polymeric lens body. The amount of WS12 releasably adhered to the polymeric lens body provides a basal tear concentration in lens wearers of 2 ?g/ml to 8 ?g/ml WS12 after 30 minutes of lens wear. The WS12-releasing contact lens can be used to increase contact lens comfort, reduce eye fatigue, reduce sensations of ocular dryness and impart a pleasant, cooling sensation in the lens wearer without causing stinging or burning upon insertion.Type: GrantFiled: October 30, 2023Date of Patent: April 15, 2025Assignee: COOPERVISION INTERNATIONAL LIMITEDInventors: Erwin Si, Nancy Keir, Subam Basuthkar Sundar Rao
