An improved method for treating the eye includes the step of providing an ophthalmic instrument including an integral wavefront sensor. The wavefront sensor measures phase aberrations in reflections directed thereto to characterize aberrations of the eye. The wavefront sensor may be operably coupled...http://www.google.com/patents/US6609794?utm_source=gb-gplus-sharePatent US6609794 - Method of treating the human eye with a wavefront sensor-based ophthalmic instrument
