Abstract: Platform or system of drop-dispenser devices and method for use thereof, where one device in a platform is active in that it is equipped with a data-recording/transmitting/processing/feedback unit configured to provide feedback on whether a drop is delivered to the ROI as intended, while another device is passive in that (being otherwise substantially structurally similar in configuration and operation to the active device), it does not have such a unit and is structured to simply hold, stabilize, and/or or position a liquid-drop container to aid in successful delivery of the liquid drop(s). While using the system, the user may start using the passive device and switch to the use of an active device if the results of delivery of drops to the ROI with the passive device is unsatisfactory with respect to a schedule, or success rate, or for any other reason.

Abstract: An opto-mechanical system for operation with a container containing a fluid to be administered in an eye or a container such as a syringe for example to administer an insulin injection. The mount of the system is equipped with an optical system and a processing/recording means configured to receive optical data, from light (visual or infra-red) reflected by an area in the vicinity of the eye, which data represents temporal and spatial characteristics of a process of administering drops of the fluid from the container into the eye. Image analysis software or human observation may be used to analyze the recorded images.

Abstract: Devices, systems, and methods for performing injections with lowered likelihood of infection include needles and other injection means with protective sleeves or sheaths. The protective sleeve can protect the needle before, during, or before and during an injection. The force needed to administer an injection or penetrate an insertion site using an injection device or system with a protective sleeve can be about the same to up to 50% more than the force needed for a system or device without a protective sleeve. The force needed to collapse the protective sleeve can be less than 100 gram-force. The material, the thickness, or both the material and the thickness of the protective sleeve may differ when comparing the portion of the sleeve near the needle tip and the portion near the base of the needle.

Abstract: A method and system of acquisition and processing of data representing oxygen saturation (OS) value of a tissue of a visual system of a subject, such as the optic nerve head and overlying artery and vein. The data is acquired at pre-determined discrete spectral points, including at least two isosbestic points, as a discrete reflectance spectrum, with the use of a multi-spectral optical imaging system that simultaneously produces a plurality of two-dimensional spectrally-discrete images by segmenting an incoming light front with secondary objectives. The OS value is assessed based on determination of areas bound by an acquired discrete reflectance spectrum and an isosbestic line.

Abstract: A micro surgical lighting instrument includes a hollow needle and a light guide received coaxially within the hollow needle and connected to a light source for transmitting light to a surgical site of a patient. The light guide has a distal end formed with an end face of circular segment shape and defined by a plane oriented orthogonal to the axis of the hollow needle, and a slanted surface adjacent the end face and extending rearwardly at an acute angle, with the slanted surface being lined by a coating for reflection of incident light rays.

Abstract: For protection of the otherwise sharp protruding end of a given instrument for use in ophthalmic or other surgery, as when the instrument is to be used only after it has traversed the major part of a scleral tunnel, a shiftable guard or shield is manipulable after it has served its function of avoiding damage to hemorrhageable tissues adjacent tunnel-wall tissue, thereby exposing the sharp end only after safely passing the hemorrhageable region. Various embodiments are described.
