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.

1. An eye treatment system for performing vision correction on an eye, the eye having a retina and ocular optics including a cornea, the system comprising:projection optics which project a reference image through the ocular optics and onto the retina when the eye is positioned for treatment; imaging optics which acquire an evaluation image from the retina through the ocular optics, the evaluation image defined by the reference image as projected through the ocular optics and as imaged through the ocular optics; and an energy transmitting element positioned relative to the imaging optics to transmit treatment energy toward the cornea for altering the ocular optics of the positioned eye.
