Filed:

Jun 11, 2009

Appl. No.:

12/456038

Inventors:

Scott E. Lewis - Ponte Vedra FL, US
Jim Edwards - Lawton OK, US
Cynthia Roberts - Columbus OH, US
Aylin Kilic - Kavaklidere-Ankara, TR

International Classification:

A61F 9/00
A61B 3/107
A61N 5/00
G02C 7/04

US Classification:

604 20, 351247, 351160 R

Abstract:

A method of improving vision by reshaping the cornea to correct for abnormal surface curvature by measuring the surface topography of the cornea, providing a rigid contact lens to reshape the cornea into a more desirable configuration, wearing the contact lens for sufficient time to achieve the reshaping, removing the contact lens, applying an alcohol solution to the epithelial layer, applying a riboflavin solution to the cornea, and subjecting the cornea to UV light for sufficient time to induce cross-linking of collagen fibers within the cornea, whereby the cornea is stabilized in the reshaped desirable configuration.

International Classification:

A61F 9/00

US Classification:

604 20

Abstract:

An improved methodology for the treatment of corneal abnormalities involving the application of a crosslinking solution, such as riboflavin, to the surface of the cornea followed by exposure to UV light such that the rigidity of the cornea is increased and stabilized, the method improved by providing a transparent contact lens that is selectively etched to create areas on the lens that either preclude or reduce penetration of UV light, thereby eliminating or reducing crosslinking for areas of the cornea that do not require stabilization while allowing penetration of UV light to areas of the cornea that do require stabilization.
