  • Publication number: 20190298459
    Abstract: A system, method, and apparatus for guiding an astigmatism correction procedure on an eye of a patient are disclosed. An example apparatus include a photosensor configured to record a pre-operative still image of an ocular target surgical site of the patient. The apparatus also includes a real-time, multidimensional visualization module configured to produce a real-time multidimensional visualization of the ocular target surgical site during an astigmatism correction procedure. The apparatus further includes a data processor configured to determine a virtual indicium that includes data for guiding the astigmatism correction procedure. The data processor uses the pre-operative still image to align the virtual indicium with the multidimensional visualization such that the virtual indicium is rotationally accurate. The data processor then displays the multidimensional visualization of the ocular target surgical site in conjunction with the virtual indicium.

  • Patent number: 10299880
    Abstract: A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a first plurality of lenses positioned along a first optical path and a first image sensor to record a first image stream of a target site from light in the first optical path. The stereoscopic visualization camera also includes a second plurality of lenses positioned along a second optical path, parallel to the first optical path, and a second image sensor to record a second image stream of the target site from light in the second optical path. The stereoscopic visualization camera also includes a processor configured to reduce spurious parallax between the first and second images streams by selecting pixel sets of pixel grids of the first and second image sensors such that zoom repeat points (“ZRP”) are located at a center of the respective pixel grids.
