A method of corneal laser surgery is disclosed. A first periphery is defined at an anterior surface of the cornea. This first periphery bounds a first planar area. A second periphery is defined within stromal tissue of the cornea. This second periphery bounds a second planar area. The second planar area is sized differently than the first planar area. A layer of stromal tissue which is bounded by the second periphery is subsequently incised. Stromal tissue between substantial portions of the first periphery and the second periphery is also incised, such ...
