摘要： System and method for imaging a target site with a housing assembly having a head unit configured to be at least partially directed towards the target site. 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 of volumetric data of the target site, respectively. A controller is configured to register the first set of volumetric data with the second set of volumetric data to create a third set of registered volumetric data. The third set of registered volumetric data and second set of 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 composite shared view of the target.

摘要： Disclosed is a system for retinal imaging. The type of image to be captured is selected by a user. Corresponding fixation stimulus is displayed on a fixation screen of the disclosed device for the subject to fix their gaze on. The device comprises illumination sources and, illumination optics and imaging optics, a 3-D accelerometer, and a camera. Signal from the 3-D accelerometer, and the video of the eye of the subject captured by camera are used by a computing device that uses AI techniques to vary the position of the fixation stimulus to obtain a stabilized image of the eye of the subject. The position of the fixation stimulus is varied to compensate for the movement of the handheld device to obtain a stabilized retinal image. Once stabilized, the image is captured.

摘要： An ophthalmic surgical system includes a chassis comprising a laser source. The system includes a gantry coupled to the chassis. The position of the gantry is adjustable. The system includes a reference interface coupled to the gantry. The reference interface comprises an attachment interface at a distal portion of the reference interface, configured to couple to a patient interface for docking with an eye. The reference interface is configured to move to a first plate position proximal to the chassis and a second plate position distal from the chassis. The system further includes an optical head unit coupled to the reference interface. The optical head unit comprises a laser scanner and a beam splitter. The optical head unit is configured to move to a first head unit position near a proximal end of the reference interface and a second head unit position which is a lockable surgical position near a distal end of the reference interface.

摘要： Methods and devices are provided to obtain refractive correction with superior visual acuity (e.g., 20/10) by achieving an astigmatism-free customized refractive correction. The astigmatism-free customized refractive correction involves obtaining an objective and precise measurement of cylindrical power in a resolution between 0.01 D and 0.10 D in an eye using an objective aberrometer, reliably relating the cylindrical axis obtained from the objective aberrometer to that in a phoroptor, determining an optimized focus error of an eye through subjective refraction with a phoroptor, generating a customized refraction by combining the objective measured cylindrical power, the objective measured cylindrical axis, and the subjectively measured focus power, fabricating a custom lens with a tolerance finer than 0.09 D based on the generated customized refraction, and delivering an ophthalmic lens that can provide an astigmatism-free refractive correction for an eye.

摘要： An OCT system comprises an OCT scan module for retinal scanning and an add-on anterior segment scanning module which includes at least one anterior segment scan lens (11) and an add-on fixation target (15) which is used to maintain the viewing direction of the eye (6) under investigation while achieving anterior segment scanning. Because the anterior segment scan module added to the exterior of an existing OCT system for retinal scanning has an add-on fixation target (15), it is possible to maintain the viewing direction of the eye (6) under investigation while carrying out anterior segment scanning without adjusting the internal beam path of the OCT system, and the OCT system of the present invention can be adapted to patients with only one functioning eye.
