A real-time refractory control system includes a laser refractive surgery instrument for modifying the refraction of the eye, an objective diagnostic apparatus for measuring the refraction and aberrations of the eye, and an aperture-sharing element to inject a refractive surgery beam and a monitoring diagnostic beam. An associated method of adjusting a refraction of an eye, includes: performing a procedure to modify the refraction of the eye; while the procedure is being performed, measuring the refraction and/or an aberration of the eye; and terminating the procedure when a change in the measured refraction and/or the measured aberration reaches a desired value.
