    摘要: Provided is an ophthalmologic apparatus including one dichroic mirror, which is arranged eccentrically with respect to an optical axis of light from an eye to be inspected to separate the light from the eye to be inspected; another dichroic mirror, which is configured to separate light separated by the one dichroic mirror by being transmitted through the one dichroic mirror; and a positive lens, which is configured to guide the light from the eye to be inspected to the one dichroic mirror as convergent light, and to guide the light from the eye to be inspected to the another dichroic mirror as divergent light, wherein an eccentric section of the one dichroic mirror and an eccentric section of the another dichroic mirror have a positional relationship of being substantially perpendicular to each other and having substantially the same eccentric amount, to thereby correct astigmatism.

    摘要: A retinal imaging device includes a camera, a light source, a projector, an I/O device and a computer. The projector emits two sets of light rays, such that one set of rays lies on an exterior surface of a first cone, and the other set of rays lie on an exterior surface of a second cone. The user adjusts the position of his or her eye relative to the camera, until the rays form a full, undistorted target image on the retina. This full, undistorted image is only seen when the pupil of the eye is positioned in the intersection of the first and second cones, and the eye is thus aligned with the camera. The user provides input, via the I/O device, that the user is seeing this image. The computer then instructs the camera to capture retinal images and the light source to simultaneously illuminate the retina.

    摘要: An ophthalmic visualization system can include an imaging device configured to acquire images of a surgical field; a computing device configured to determine an area of interest based on the images; and a display device in communication with the computing device and a surgical microscope, wherein the display device is configured to provide a graphical overlay onto at least a portion of a field of view of the surgical microscope, and wherein the graphical overlay includes a magnified image of the area of interest. A method of visualizing an ophthalmic procedure can include receiving images of a surgical field acquired by an imaging device; identifying an area of interest; generating a graphical overlay including a magnified image of the area of the interest; and outputting the graphical overlay to a display device such that the graphical overlay is positioned over a field of view of a surgical microscope.
