摘要： An ophthalmic apparatus includes an interference optical system, an optical scanner controller, and a correction controller. The interference optical system includes an astigmatism correction optical member and an optical scanner, and is configured to split light from a light source into reference light and measurement light, to irradiate the measurement light onto the subject’s eye via the astigmatism correction optical member and the optical scanner, and to detect interference light between returning light of the measurement light from the subject’s eye and the reference light. The optical scanner controller is configured to control the optical scanner so as to deflect the measurement light in a horizontal direction and a vertical direction on a plane perpendicular to an optical axis of the interference optical system. The correction controller is configured to control the astigmatism correction optical member so as to correct astigmatism based on a detection result of the interference light obtained by the interference optical system.

摘要： A system for extracting lens material from an eye including an instrument having a first aspiration pump driven by a drive mechanism having a motor, and an elongate member sized and configured to extend through an anterior chamber to a capsular bag of the eye. The elongate member configured to be oscillated by the drive mechanism includes an inner lumen fluidly coupled to the first aspiration pump and defining at least a portion of an aspiration waste line, and an open distal end having a distal cutting tip. The system can further include a fluid system remote from the surgical instrument including a second aspiration pump and a fluid line configured to deliver background aspiration from the second aspiration pump to the inner lumen of the elongate member to aspirate the lens material from the eye towards the inner lumen. Related devices, systems, and methods are also provided.

摘要： An example multi-fiber, multi-spot laser probe comprises a plurality of fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the plurality of fibers along at least a portion of the laser probe at or near the distal end of the laser probe, where a distal end of each of the plurality of fibers is angle-polished so that the distal end of each fiber is angled relative to a longitudinal axis of the cannula and relative to a plane perpendicular to the longitudinal axis of the cannula. Additional embodiments employ lensed fibers, a distal window, ball lens, lens array, or faceted wedge.

摘要： A device for visualizing an irido-corneal angle of an eye through a window of a patient interface configured to be placed on the eye includes and optics structure and at least one imaging apparatus. The optics structure is configured to engage with the patient interface to provide a line of sight through the window in the direction of the irido-corneal angle, and to subsequently disengage from the patient interface. The imaging apparatus is associated with the optics structure and aligned with the line of sight to enable capturing an image of the eye including the irido-corneal angle.

摘要： A vacuum device comprises a vacuum generator and a vacuum interface for fluidically coupling the vacuum generator to a vacuum cavity for affixing an ophthalmological patient interface on a patient's eye. The vacuum device comprises a movement detector which is configured to detect movements of the patient's eye and a control unit that is configured to detect a faulty fluidic coupling of the vacuum cavity on the basis of a pressure that is ascertained by a coupled pressure sensor and to produce a control signal for interrupting an ophthalmological treatment that is carried out by an ophthalmological treatment device if an eye movement is detected by the movement detector at the same time as the detected faulty fluidic coupling of the vacuum cavity.

摘要： An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.

摘要： A method of controlling an eye surgical laser is disclosed for the separation of a volume body with predefined posterior and anterior interfaces from a human/animal cornea. The method including controlling the laser with a control device, the laser being configured to emit pulsed laser pulses in a predefined pattern into the cornea. The posterior and anterior interfaces of the volume body are defined by the predefined pattern and are generated by an interaction of the individual laser pulses with the cornea through photodisruption. The control device controls the laser beam such that both interfaces are generated via a continuous, uninterrupted sequence of laser pulses. A treatment device is disclosed with at least one eye surgical laser for the separation of a predefined corneal volume with predefined interfaces of a human/animal eye by photodisruption and with at least one control device for the laser(s).
