Abstract
An oleic acid-releasing contact lens is described as well as method of manufacturing the same. The oleic acid-releasing contact lens contains oleic acid releasably adhered to the polymeric lens body, and releases from 2 μg to 25 μg oleic acid after 1 hour in a release media. The oleic acid-releasing contact lens can be comfortably worn by a symptomatic contact lens wearer, and can increase the duration of comfortable lens wearing time and/or reduce lens awareness events in a symptomatic contact lens wearer.
Claims16
An unworn sterile silicone hydrogel contact lens immersed in a packaging solution and sealed in a package, said contact lens comprising:
- (a) a polymeric lens body that is the reaction product of a polymerizable composition comprising at least one siloxane monomer and at least one hydrophilic monomer or at least one hydrophilic polymer or both at least one hydrophilic monomer and at least one hydrophilic polymer;
- and
- (b) an amount of oleic acid releasably adhered to the polymeric lens body, wherein the contact lens has a release profile in a release media consisting of 30 vol % EtOH in PBS comprising release of 2 μg to 25 μg oleic acid at 1 hour.
