APERTURE-OPTIONAL HEAD-MOUNTED LOW-LIGHT FUNDUS IMAGING DEVICE
An aperture-optional head-mounted low-light fundus camera is provided. A fundus camera is configured to enclose a patient's eyes, orient imaging paths of image sensors and lenses towards the patient's eyes without requiring integral aperture stops within the enclosure, and provide non-pupillary low-light illumination for fundus imaging within the enclosure. The aperture-optional head-mounted low-light fundus camera can be worn by a patient during use without limiting the patient's movement or posture, alleviating awkwardness and discomfort caused to the patient by conventional fundus cameras. The aperture-optional head-mounted low-light fundus camera further improves image capture quality over conventional fundus cameras, by removing the need to use dexterity to align with eye pupil, minimizing image blur from errant movement, and eliminating visual artifacts from glares, haloes, reflections, and the like.
Apparatus with filter to treat macular degeneration and method of treating macular degeneration
An apparatus is disclosed for treating macular degeneration including an optical filter configured to be mated with the ophthalmic lens, the filter having a surface wherein at least a portion of the surface comprises non-transmissive material that may distribute power from a light beam creating a plurality of light beams. A method of treating macular degeneration using the optical filter is also disclosed.
Imaging probes and associated devices, systems, and methods utilizing electroactive polymer actuators
Devices, systems, and methods that utilize electroactive polymer actuators to impart motion to an optical fiber positioned within an imaging probe are provided. In some embodiments, an ophthalmic imaging apparatus comprises an optical probe having a handle sized and shaped for handheld grasping by a user; and a cannula coupled to the handle, the cannula sized and shaped for insertion into an eye to be treated; an optical fiber positioned at least partially within the optical probe, the optical fiber configured to receive an imaging light from an imaging light source and guide the imaging light to an optical element positioned within the cannula of the optical probe; and an actuator system configured to impart motion to the optical fiber, the actuator system including an electroactive polymer (EAP) actuator positioned within the optical probe.
SYSTEM AND METHOD FOR RETINAL IMAGING
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.
Portable medical diagnostics device with integrated artificial intelligence capabilities
A handheld, portable devices with integrated artificial intelligence (AI) configured to assess a patient's body part to detect a disease and methods of operating such devices are disclosed. In some cases, a device can be a retina camera configured to assess a patient's retina and, by using an on-board AI retinal disease detection system, provide real-time analysis and diagnosis of the patient's retina. Easy and comfortable visualization of the patient's retina can be facilitated using such retina camera, which can be placed over the patient's eye, display the retina image on a high-resolution display, analyze a captured image by the on-board AI system, and provide determination of presence of a disease.
Tunable-Lens-Based Refractive Examination
An apparatus, and corresponding method, for determining a refractive property of an eye includes a housing with a port configured to receive an eye and also light from the eye. A tunable lens can be mounted to the housing to apply a variable focal power to the light from the eye and to pass the light along an optical path toward a wavefront sensor within the housing. The wavefront sensor can receive the light via the optical path and measure a wavefront thereof. A determination module can be configured to determine a property of the eye based on the wavefront. Embodiments can be handheld, portable, and open view, while providing objective wavefront aberrometry, subjective phoroptry, and accommodation and presbyoptic evaluation, as well as lensometry functions.
Self-illuminated handheld lens for retinal examination and photography and related method thereof
System and method directed towards providing full and even illumination of a patient's retina through lighting integrated into a handheld fundus lens. By integrating the lighting, the method and system reduces and even eliminate many lens artifacts and reflections. By increasing the accuracy, quality, and field of view afforded during clinical examination of the retina, the method and system will allow practitioners to make more accurate diagnoses and will increase safety during retinal surgical procedures.

SYSTEM FOR FUNDUS IMAGING
The invention provides an imaging system (102) for imaging a fundus (104) of an eye (106), which has an optical axis (116). The imaging system (102) has a light source (108), an illumination path (118) along which light travels from the light source (108) to the eye (106), a light sensor (10) and imaging optics (44) defining an imaging axis (114), and at least one objective lens (112) aligned with the optical axis (116). At least a part of the illumination path (118) is substantially coaxial with the imaging axis (114), and the optical axis (116) is tilted with respect to the imaging axis (114).
Body mounted Laser Indirect Ophthalmoscope (LIO) system
A body-mounted laser-indirect ophthalmoscope (LIO) system for delivering laser energy into an eye of a patient includes a wearable assembly which secures a control module, laser module, and/or power module (including a battery) to the body of the user. The control module receives activation signals and parameter information from an activation unit a mobile computing device and controls the laser energy emitted by the laser module based on the parameter information. The parameter information is user-provided via a graphical user interface or by voice control (e.g. recognizing voice commands in audio data captured by the mobile computing device). In the preferred embodiment, the wearable assembly includes only a headset, in which case the control, power and laser modules are provided on the headset; however, an alternative embodiment includes a utility belt from which a fiber optic cable for emitting the laser energy is routed to the headset.
