Embodiment Construction

[0019] The present invention relates to a contact lens that is effective in promoting the health of the epithelium of the eye on which the lens is placed. Accordingly, the contact lenses disclosed herein seek to reduce the irritation associated with traditional contact lenses. Additionally, the contact lenses are effective in treating or reducing dry eye-like sensations and are effective in reducing the likelihood of eye infections.

[0020] A contact lens according to the disclosure herein includes a contact lens body and an epidermal growth factor (EGF) component provided on or in the contact lens body. A contact lens according to the present invention refers to a lens, such as a tinted or colored lens, placed on or over the epithelium of the eye for vision correction and / or cosmetic purposes. In other words, the contact lens includes a lens body having a front surface and a back surface. The anterior surface is structured or shaped for placement on the epithelium of the e...

Abstract

A contact lens (14) is described that comprises a lens body and an epithelial growth factor (EGF) component. The EGF component is effective in maintaining a healthy epithelium of an eye on which the lens is placed. The EGF component includes an EGF, and preferably a human EGF. The lens (14) may be effective in reducing irritation associated with conventional contact lenses, and also may be effective in treating dry eye and / or reducing infection of an eye. Packaging systems (10) and method of manufacturing such lenses are also described.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of US Provisional Application No. 60 / 551,834, filed March 10, 2004, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to contact lenses, packages containing contact lenses and methods for making contact lenses. More specifically, the present invention relates to contact lenses (e.g., disposable contact lenses) that include an epidermal growth factor component effective to promote the health of the epithelium of the eye in which the contact lens is worn, and It relates to a packaging group for the contact lens and a method for making the contact lens. Background technique [0004] US Patent No. 5,112,350 discloses a method for placing an artificial lens made of collagen hydrogel to promote epithelial cell growth and stromal regeneration on the cornea. The method includes attaching an artificial lens to Bowman's membrane. Th...
