SURGICAL MICROSCOPE WITH INTEGRATED OPTICAL COHERENCE TOMOGRAPHY AND DISPLAY SYSTEMS
An ophthalmic surgical microscope includes a beam coupler positioned along an optical path of the surgical microscope between a first eyepiece and magnifying/focusing optics, the beam coupler operable to direct the OCT imaging beam along a first portion of the optical path of the surgical microscope between the beam coupler and a patient's eye (an OCT image being generated based on a reflected portion of the OCT imaging beam). The surgical microscope additionally includes a real-time data projection unit operable to project the OCT image generated by the OCT system and a beam splitter positioned along the optical path of the surgical microscope between a second eyepiece and the magnifying/focusing optics. The beam splitter is operable to direct the projected OCT image along a second portion of the optical path of the surgical microscope between the beam splitter and the second eyepiece such that the projected OCT image is viewable through the second eyepiece.
MULTIPLE OFF-AXIS CHANNEL OPTICAL IMAGING DEVICE WITH OVERLAP TO REMOVE AN ARTIFACT FROM A PRIMARY FIXATION TARGET
An optical imaging device includes a support structure and imaging channels, where each imaging channel includes a discrete optical imaging pathway. The imaging channels may be disposed within the support structure, and the imaging channels may be aimed at different angles relative to each other such that each optical imaging pathway is directed towards a pupil of the eye. Additionally, the optical imaging device may include a primary fixation target configured to emit optical signals along a primary fixation target projection path towards the pupil of the eye. Further, an artifact of the primary fixation target may be generated onto a portion of the eye to be imaged.
MEDICAL STEREOSCOPIC OBSERVATION DEVICE, MEDICAL STEREOSCOPIC OBSERVATION METHOD, AND PROGRAM
To reduce more load related to the correction of deformation of an observation image that is caused by an error between a plurality of imaging sections.
A medical stereoscopic observation device includes: an acquisition section configured to acquire, from an imaging unit including a first imaging section configured to capture a left-eye image and a second imaging section configured to capture a right-eye image, correction data for correcting an error related to capturing of an image between the first imaging section and the second imaging section, the imaging unit being rotatably held by a support section; and a correction section configured to correct a difference of parallax between the left-eye image and the right-eye image on a basis of the correction data, using a position corresponding to a rotation axis of the imaging unit as a reference position.
OPTOELECTRONIC BINOCULAR INSTRUMENT FOR THE CORRECTION OF PRESBYOPIA AND METHOD FOR THE BINOCULAR CORRECTION OF PRESBYOPIA
Optoelectronic binocular instrument for the automatic correction of presbyopia and method for the binocular correction of the presbyopia. The instrument has two optoelectronic lenses (103, 110; 203, 204) and a capturing subsystem for taking images of the eye. By means of the pupil tracking, which performs the processing of the eye's images, the system determines the distance where the subject is looking at. The pupil tracking works at a very high speed, using a high-performance graphic processor and a highly parallelized algorithm for pupil tracking. The method consists of two phases. In the first one a calibration is accomplished, the subject is asked to look at targets at different distances and the size and position of the pupil is measured. In the second phase the correction is performed by the instrument, the system continuously captures and processes images to calculate the correction to apply and, finally, corrects the presbyopia by applying said correction.
Apparatus for retinoscopy
The present invention provides a retinoscope comprising: a refractor that has a lens module therein and is located at a predetermined distance from eyes of a person to be tested such that a line of sight of the person to be tested passes through an optometry window, wherein the lens module is configured such that a plurality of lenses necessary for correction are selectively located on the optometry window in order to obtain a correction value for correcting the eyes of the person to be tested; a main body for supporting the refractor; a retinoscope unit coupled to one surface of the main body and maintained at a predetermined distance from the refractor, wherein the retinoscope unit radiates light beams to the eyes of the person to be tested so as to be close to the line of sight of the person to be tested and rotates or reciprocates the light beams when receiving a signal of an operating unit; and the operating unit that operates driving of the refractor and the retinoscope unit.
Ophthalmic imaging device for imaging posterior and anterior eye regions
An ophthalmic imaging device (300) includes a fundus module (210) and a slit lamp 5 module (220) movably coupled to each other. The fundus module (210) includes an illumination module (230) and an imaging module (240). The illumination module (230) is adapted to yield a first partially blocked beam. The imaging module (240) includes a mirror (324) with a hole and an objective lens (326) to produce a reflected first partially blocked beam and a second partially blocked beam, to form a cornea 10 illuminating doughnut (502) and pupil illuminating doughnut (504), respectively, on an anterior region of the eye and form an image of the posterior\\region of the eye on an image plane (346). The slit lamp module (220) is adapted to view and capture the image of anterior and posterior regions of the eye.
OCT-ENABLED INJECTION FOR VITREORETINAL SURGERY
OCT-enabled injection for vitreoretinal surgery may involve using an OCT image to detect when a surgical injector penetrates a desired tissue layer of the eye for receiving an injection. The injection may be triggered or automatically actuated based on the detection of the surgical injector from the OCT image.
Devices and Method for Generating A Stimulus to Evaluate Ocular Sensitivity
