A method for measuring an optical system comprises transmitting an image with the optical system. Gradients of the optical system can be determined by separating the transmitted image with a lenslet array. An error-correcting change in the shape of the optical system can be mapped by integrating across the gradients. The change in elevation around the path is related to the accuracy of the gradient array. A system for measuring a wavefront of an eye includes an image source for projecting an image into the eye, lenslets, a detector for measuring angles of light rays of an optical surface of an eye, and a computer for mapping the errors of the eye. A tomographic wavefront map is made by deflecting the measurement path of the wavefront sensor. Aberrations are selected for treatment in response to an order of the aberration and a tissue structure corresponding to the aberration.

What is claimed is: 1. A method of determining an accuracy of a gradient array in an optical tissue measurement comprising:transmitting an image through the optical tissue;determining local gradients of the array across the optical tissue from the transmitted image;integrating along a closed integration path across a portion of the array; anddetermining the accuracy of the gradient array based on the integration,wherein the integration is performed so as to map an error-correcting change in optical tissues.
