  • a photosensor configured to record a patient specific pre-operative still image of the eye prior to cyclorotation of the eye when the patient lies down for surgery;

    at least one real-time, multidimensional visualization module including a second photosensor and an image processor, the module configured to produce a real-time multidimensional visualization of the eye on at least one display; and

    at least one data processor configured to utilize the patient specific pre-operative still image to;

    i) produce at least one virtual surgical reference indicium including an ocular natural vertical axis of the eye, andii) align the at least one virtual surgical reference indicium to the eye in conjunction with the real-time multidimensional visualization of at least a portion of the eye,wherein the at least one patient specific pre-operative still image is captured under a dilation condition selected from the group consisting of natural dilation, chemical dilation, and no dilation.
