Abstract:
1. An apparatus comprising: a real-time wavefront sensor configured to continually sample a first set of wavefronts returned from an eye of a patient over a time interval during which an accommodation of the eye of the patient is being changed, and with the real-time wavefront sensor configured to output wavefront measurement data characterizing the first set of wavefronts; an internal fixation module configured to project an image onto the eye of the patient to change the accommodation of the eye of the patient; and a controller, coupled to the wavefront sensor and the internal fixation module, with the controller configured to monitor the output wavefront measurement data and compare the first set of wavefronts to reference wavefronts while controlling the internal fixation module to change the accommodation of the eye of the patient during the time interval and with the controller further configured to indicate when the change of accommodation causes the first set of wavefronts to substantially differ from the reference wavefronts to indicate accommodation limit(s) of the eye of the patient.
