An ophthalmic microscope including an observation optical system having a first focal point in front of an eye; an objective auxiliary lens positionable on the eye side of an objective lens in the observation optical system or releasable therefrom, a focal point when the objective auxiliary lens is positioned to a second focal point on an anterior ocular eye position; and a front lens positionable further toward the eye side than the first focal point or releasable from the position, a focal point through the eye's crystalline lens when the front lens is set to a third focal point and a posterior ocular segment position of the eye, the objective auxiliary lens set and the front lens released during anterior ocular segment observation, the front lens set and the objective auxiliary lens released during posterior ocular segment observation, without changing a positional relationship between the objective lens and eye.

An eye surgery visualization system includes an image sensor and contains an imaging system for producing an image of an object region with an optical imaging beam path in an imaging plane on an image sensor. A computer unit has an image processing routine for an image of the object region, the image having been captured by the image sensor. An image display unit visualizes image data of an image processed in the computer unit. An ophthalmoscopy loupe of the system images a portion lying within a patient's eye in an intermediate image plane that is conjugate to the imaging plane on the image sensor. The image processing routine separates the first portions of the image of the object region from second portions of the image of the object region in the imaging plane on the image sensor.

An ophthalmologic apparatus comprises an optical system that acquires data of an anterior segment of a subject's eye or a fundus of the subject's eye, an imaging unit that images the anterior segment or the fundus, a movement mechanism that moves the subject's eye and the optical system relative to each other, and a controller that controls die movement mechanism. The controller controls the movement mechanism so as to maintain a positional relationship between the subject's eye and the optical system based on an anterior segment image acquired by the imaging unit in an anterior segment mode for acquiring data of the anterior segment by the optical system, and controls the movement mechanism so as to maintain the positional relationship based on a fundus image acquired by the imaging unit in a fundus mode for acquiring data of the fundus by the optical system.

An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination.

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data.

Systems and methods for high-resolution, wide-angle viewing of a retina of an eye using an ophthalmic microscope that can view a high-resolution image of a retina formed using a wide field of view optical system. A wide field of view optical system can involve a first lens having a diffractive surface on at least one surface and a second lens housing in a shared housing. A wide field of view optical system can involve one or more lens formed from an optical grade polymer and manufactured at a cost that allows the lens to be disposable.

A slit lamp device for use in an ophthalmoscope includes one or more light sources for providing a light path comprised of one or more beams of: visible light and infrared (IR) light; a slit lamp control mechanism along the light path for receiving the one or more light beams and forming the one or more light beams into a slit light beam; the slit lamp control mechanism further controlling the width of the formed slit light beam; a first, narrow slit passes visible light through the slit control mechanism and a second, wider slit passes IR light though the slit control mechanism.

An ophthalmic microscope assembly has an ophthalmic microscope with a camera, a voice recorder with speech-to-text conversion, a measurement unit for carrying out measurements, and a report generator for generating reports. Depending on the physical input, such as the voice data from the voice recorder, the image data from the camera, the data measured by the measurement unit, as well as the current operating settings of the microscope, report generator automatically generates a report. Depending on the same data, a guide automatically generates guidance to the user and/or performs measurements and takes images. A microphone is placed below the ocular or on the frame of a display of the microscope.

A system for guiding an ophthalmic procedure is disclosed. The system includes a housing assembly with a head unit configured to be at least partially directed towards a target site in an eye. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second set of volumetric data, respectively. A controller is configured to register the first set and second set of volumetric data to create a third set of registered volumetric data. The third set and second set of registered volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a shared composite view of the target site. The controller is configured to extract structural features and/or enable visualization of the target site.

The present disclosure provides a head tracking control system including at least one marker positioned on a head of a surgeon. The system further includes an infrared camera including at least two infrared sensors and that detects infrared light reflected off the at least one marker and sends a signal corresponding to the detected light to a processor, and that executes instructions on the processor to detect a movement of the at least one marker. The system also includes an intelligent tracking system that executes instructions on the processor to determine if the detected movement of the at least one marker corresponds to a defined head movement of the surgeon. The system further includes an ophthalmic surgical microscope including the processor. If the detected movement of the at least one marker corresponds to the defined head movement of the surgeon, the processor executes instructions to control the ophthalmic surgical microscope.
