Disclosed herein are viewing systems configured for viewing an image of a biological object illuminated with light and a viewing device (e.g., loupes, glasses, etc.) and methods for operation thereof. The viewing device comprises a plurality of viewing modes: a white light mode, a fluorescent light mode, and an overlay mode, and a shutter that opens and closes in accordance with the viewing mode. An overlay image is an image of the biological object when the biological object is illuminated with both white light and fluorescent light, causing the overlay image to be an overlay of the white light image and the fluorescent light image. The disclosed systems and methods allow a user (e.g., a surgeon, medical staff, etc.) to preserve the ergonomics offered by eyewear while providing fluorescent viewing capabilities, particularly with visible fluorescent dyes.

Multiple embodiments of a lighted loupe system are presented. The lighted loupe system is suitable for Galilean and Keplerian telescopic or loop configurations, where light may be applied to an object being viewed without shadows being formed on the object.

An ocular surgery visualization system has an ophthalmoscopic loupe that images a portion located within a patient's eye in an intermediate image plane. An image processing routine separates a first portion of an image of a target region in the imaging plane from a second portion of the image of the target region, the first portion being captured by an image sensor and resulting from an imaging beam path through the ophthalmoscopic loupe, the second portion being captured by the image sensor and resulting from an imaging beam path extending beyond the ophthalmoscopic loupe and being complementary to the first portion, so as to transform the first portion of the image of the target region into a mirror first portion by a congruence corresponding to a rotation of the first portion around an axis of rotation perpendicular to the image plane or by a congruence corresponding to a point mirror, and so as to combine the rotated or point mirror first portion and the second portion to form a target region composite image that is provided to an image display device.

A prismatic deflection loupe comprises an ocular optics at a fixed ocular position; a prism at a fixed position to deflect an image embedded in an input light field and to direct said input light fiel

The invention disclosed relates to a removable eyewear filter system configured to by placed on a surgical or dental eyewear that includes loupe or magnification devices that allow for the filtering of light wavelengths for the purpose of viewing areas that may be generating a fluorescent light, where the removable eyewear filter system includes a frame incorporating a plurality of lens, each of which includes a loupe of known magnification and a filter element, removably attachable to the frame, includes a first section substantially adjacent the lens and a second section substantially adjacent a distal end of the loupes, wherein the filter elements are configured to attenuate light wavelengths in an undesired wavelength band and allow light wavelengths in a desired wavelength band to pass substantially unattenuated.

A computer-implemented method for displaying augmented reality (AR) content within an AR device coupled to one or more loupe lenses comprising: obtaining calibration parameters defining a magnified display portion within a display of the AR device, wherein the magnified display portion corresponds to boundaries encompassing the one or more loupe lenses; receiving the AR content for display within the AR device; and rendering the AR content within the display, wherein the rendering the AR content comprises: identifying a magnified portion of the AR content to be displayed within the magnified display portion, and rendering the magnified portion of the AR content within the magnified display portion.

A loupe supporting eyewear system has loupe supporting shelves removably couplable to eyewear frames that are configured to hold loupes and monocles of varying dimensions and sizes. The loupe supporting eyewear system may be configured to hold the loupe in front of either the left or right eye, or both. The interchangeable loupe supporting shelves accommodate loupes for use across multiple industries, including gemology, dentistry, watchmaking, coin collecting, and others. The loupe supporting eyewear system is cross-compatible with a user's preexisting loupes.

The present invention includes a novel procedure and corresponding medical devices for a Purcutaneous Spinal Interbody Fusion (PSIF). In PSIF, the surgeon performs the entire operation percutaneously without the use of a microscope, endoscope, or magnifying loupes. An adjustable retractor system is disclosed that enables the surgeon to percutaneously perform the surgery through accessing the facet joint (and later disc space) that was created by said retractor system. This retractor system provides the surgeon a safe area to work and operate without fear of damaging nerves, blood vessels, or other tissue. An expanding trial may be inserted into and removed from the disc space through the interior of the retractor system to determine the proper size for the expandable cage. The retractor system also enables the expandable cage to be inserted into the disc space.
