Corneal onlays and wavefront aberration correction to enhance vision
First Claim
Patent Images
1. A method for enhancing vision of an individual comprising:
- measuring a wavefront aberration of an eye of an individual, the eye comprising an epithelial cell layer and a Bowman'"'"'s membrane; and
a step selected from the group consisting of;
altering an ocular implant element based on the measured wavefront aberration to provide a correction for the wavefront aberration when the altered ocular implant element is located in an eye between the epithelial cell layer and the Bowman'"'"'s membrane, and molding a corneal onlay having an ocular power effective in correcting the vision of an eye of an individual, and ablating a portion of the eye of the individual to correct the measured wavefront aberration.

Abstract
Devices and methods for improving vision are described. The vision of a person can be corrected using a corneal onlay or a lens positioned between an epithelial cell layer and Bowman'"'"'s membrane of the person'"'"'s eye. Wavefront aberrations are measured for the person'"'"'s eye or eyes, and the aberrations are used to shape the corneal onlay to provide a desired vision correction power, or to shape the person'"'"'s cornea.

7. A method of producing a corneal onlay, comprising:
-
measuring a wavefront aberration of an eye of an individual, the eye comprising an epithelial cell layer and a Bowman'"'"'s membrane; and
a step selected from the group consisting of;
altering an ocular blank without a corrective ocular power to provide a correction for the wavefront aberration of the eye of the individual when the altered ocular blank is located between the epithelial cell layer and the Bowman'"'"'s membrane, and altering at least a portion of a lens having a fixed optical power to provide a correction for the wavefront aberration of the eye of the individual when the altered lens is located between the epithelial cell layer and the Bowman'"'"'s membrane. - View Dependent Claims (8, 9, 10, 11)
