Real-time surgical reference indicium apparatus and methods for intraocular lens implantation
First Claim
1. An apparatus for guiding a surgical procedure on an eye of a patient, the apparatus comprising:
- 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.

Abstract
Described herein are apparatus and associated methods for the generation of at least one user adjustable, accurate, real-time, virtual surgical reference indicium including natural patient vertical for use in ocular surgery. The apparatus used to generate real-time, virtual surgical reference indicium including natural patient vertical includes one or more real-time, multidimensional visualization modules, one or more data processors configured to produce real-time, virtual surgical reference indicia, and at least one user control input for adjusting the at least one real-time virtual surgical reference indicium including natural patient vertical. The associated methods generally involve the steps of providing one or more real-time multidimensional visualizations of a target surgical field, identifying at least one visual feature in a pre-operative dataset, aligning the visual features with the multidimensional visualization, and incorporating one or more real-time, virtual surgical reference indicium including natural patient vertical into the real-time visualization.
