Abstract: Described herein are apparatus and associated methods for the generation of at least one user adjustable, accurate, real-time, virtual surgical reference indicium. A method includes recording an image of an eye and producing a real-time multidimensional visualization using the recorded image. The method also includes determining at least one distinct visible feature within a patient specific pre-operative still image and producing the real-time, virtual surgical reference indicium in conjunction with the patient specific pre-operative still image. The method further includes aligning the real-time, virtual surgical reference indicium with the real-time, multidimensional visualization of the eye using the at least one distinct visible feature.

Abstract: A system, method, and apparatus for performing intraocular lens implantation using real-time surgical reference indicium are disclosed. An example method includes recording a patient specific pre-operative still image of an eye prior to cyclorotation of the eye when a patient lies down for surgery and generating at least one real-time multidimensional visualization of at least a portion of the eye for display. The method further includes using the patient specific pre-operative still image to at least produce at least one virtual surgical reference indicium including an ocular natural vertical axis of the eye and 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. The 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.
