Abstract
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, and releases from 0.05 μg to 0.5 μg WS12 after 1 hour in a release media or when worn by a human subject. The WS12-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 and/or reduce contact lens dryness in a symptomatic contact lens wearer.
Claims20
An unworn sterile hydrogel contact lens immersed in a packaging solution and sealed in a package, said contact lens comprising:
- (a) a polymeric lens body;
- and
- (b) an amount of N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide releasably adhered to the polymeric lens body.
A contact lens immersed in a packaging solution and sealed in a package, said contact lens is unworn sterile silicone hydrogel contact lens and comprising:
- (a) a polymeric lens body;
- and
- (b) an amount of N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide releasably adhered to the polymeric lens body, wherein the contact lens releases from 0.05 μg to 0.50 μg N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide after one hour of wear by a human subject.
A kit comprising at least two N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide releasing contact lenses, wherein a first contact lens comprises a first polymeric lens body and a first amount of N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide releasably adhered to the first polymeric lens body, and a second contact lens comprising a second polymeric lens body and a second amount of N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide releasably adhered to the second polymeric lens body, wherein the second amount is greater than the first amount, and wherein the first polymeric lens body and the second polymeric lens body comprise the same material.
