First Claim
Patent Images
1. A method for improving vision of a presbyopic person, the method comprising:
- placing a corneal onlay lens in contact with an eye of a presbyopic person, the eye having a corneal epithelium, such that the corneal epithelium of the eye covers an anterior surface of the lens and a posterior surface of the lens contacts Bowman'"'"'s membrane of the ye, the corneal onlay lens having a lens body diameter less than 5 mm and structure to improve vision of the presbyopic person.

Abstract
Methods for improving vision in a person diagnosed with presbyopia include placing a corneal onlay lens having a lens body diameter less than 5 mm in contact with an eye of the person. The corneal onlay lens has at least one refractive region having a refractive power to correct vision effects caused by the presbyopia. If the person is a presbyopic emmetrope, the method may include a step of placing only one corneal onlay lens in the person to treat presbyopia or improve the vision of the person. Additional corneal onlay lenses and methods of making such corneal onlay lenses are also described.

13. A corneal onlay, comprising:
a lens body having a corneal epithelium contactable anterior surface, an opposing Bowman'"'"'s membrane contactable posterior surface, a lens body diameter less than 5 mm, and a refractive region having a refractive power for improving the vision of an eye of a presbyopic person when he corneal onlay lens is located between the corneal epithelium and Bowman'"'"'s membrane of the eye of the presbyopic person. - View Dependent Claims (14, 15, 16)
