1. A method of correcting vision for presbyopia, comprising:
remodeling the stroma with a laser to create an intracorneal shape, wherein the corneal shape includes a central region with a thickness that is about 50 microns or less measured from an extension of a shape of a peripheral region of the corneal shape, wherein remodeling a portion of the stroma increases a curvature of a central portion of the anterior surface of the cornea with a central elevation change for near vision while allowing distance vision in a region peripheral to the central portion; wherein the corneal shape compensates for epithelial remodeling of the epithelial layer of the cornea in response to remodeling the stroma, and wherein the central region with a thickness that is about 50 microns or less measured from an extension of a shape of the peripheral region of the corneal ablation shape is 3 to 7 times the central elevation change. |
