<p>The invention provides laser eye surgery devices, systems, and methods which measure the refractive error in the eye before, during, and/or after vision correction surgery. The invention allows adjustments during the vision correction operation, and allows qualitative and/or quantitative measurements of the progress of photorefractive treatments by projecting and imaging reference images though the cornea and other components of the ocular optical system. A slope of an image quality value such as an Optical Transfer Function may be monitored during the procedure to help determine when to terminate treatment.</p> |
