Real-time surgical reference indicium apparatus and methods for intraocular lens implantation

An apparatus for stereoscopically 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, and
• ii) 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 real-time, multidimensional visualization is three-dimensional (3D).

An apparatus for stereoscopically guiding an intraocular lens implantation, said apparatus comprising:

• a photosensor configured to record a patient specific pre-operative still image of a non-cyclorotated eye of a patient 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 three-dimensional, high definition real-time multidimensional visualization of a surgical field on at least one display;
• and
• at least one data processor configured to utilize at least one 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, and
• ii) align the at least one virtual surgical reference indicium including to the eye in conjunction with the real-time multidimensional visualization of said surgical field for positioning of an intraocular lens with the ocular natural vertical axis.
