  • Patent number: 11369266
    Abstract: An OCT system for measuring a retina as part of an eye health monitoring and diagnosis system. The OCT system includes an OCT interferometer, where the interferometer comprises a light source or measurement beam and a scanner for moving the beam on the retina of a patient's eye, and a processor configured to execute instructions to cause the scanner to move the measurement beam on the retina in a scan pattern. The scan pattern is a continuous pattern that includes a plurality of lobes. The measurement beam may be caused to move on the retina by the motion of a mirror that intercepts and redirects the measurement beam. The mirror position may be altered by the application of a drive signal to one or more actuators that respond to the drive signal by rotating the mirror about an axis or axes.

  • Patent number: 11215814
    Abstract: An ophthalmic laser system uses a non-confocal configuration to determine a laser beam focus position relative to the patient interface (PI) surface. The system includes a light intensity detector with no confocal lens or pinhole between the detector and the objective lens. When the objective focuses the light to a target focus point inside the PI lens at a particular offset from its distal surface, the light signal at the detector peaks. The offset value is determined by fixed system parameters, and can also be empirically determined by directly measuring the PI lens surface by observing the effect of plasma formation at the glass surface. During ophthalmic procedures, the laser focus is first scanned insider the PI lens, and the target focus point location is determined from the peak of the detector signal. The known offset value is then added to obtain the location of the PI lens surface.

  • Patent number: 11000413
    Abstract: In an ophthalmic laser surgical system, a real-time optical coherence tomography (OCT) measurement method acquires OCT data during laser treatment. The treatment laser beam and OCT sample beam are generated simultaneously, and the optical delivery system scans them simultaneously in the eye tissue, where the focus of the treatment laser beam and the focus of the OCT beam coincide with each other in space. While both beams simultaneously scanned in the eye tissue, the OCT device detects returned OCT light from the sample during a data acquisition period, and generates an OCT A-scan based on the detected OCT light. Based on the A-scan, a controller determines a structure of the eye in a depth direction relative to the focus of the OCT beam, and controls the operations ophthalmic laser surgical system accordingly. One exemplary application is the formation of an arcuate corneal incision in cataract surgery.

  • Patent number: 9393156
    Abstract: Some embodiments disclosed here provide for a method fragmenting a cataractous lens of a patient's eye using an ultra-short pulsed laser. The method can include determining, within a lens of a patient's eye, a high NA zone where a cone angle of a laser beam with a high numerical aperture is not shadowed by the iris, and a low NA zone radially closer to the iris where the cone angle of the laser beam with a low numerical aperture is not shadowed by the iris. Laser lens fragmentation is accomplished by delivering the laser beam with the high numerical aperture to the high NA zone, and the laser beam with the low numerical aperture to the low NA zone. This can result in a more effective fragmentation of a nucleus of the lens without exposing the retina to radiation above safety standards.

  • Patent number: 9304722
    Abstract: An image processing apparatus that is capable of performing report printing in a language desired by a user in either manual report printing or autonomic report printing. A storage unit stores information on the image processing apparatus. A touch panel receives input from a log-in user A control unit controls execution of the automatic report printing in which the information is printed by the printing unit as a report when predetermined conditions are satisfied, and execution of the manual report printing in which the information is printed by the printing unit as a report based on an instruction from the log-in user. The control unit performs the automatic report printing in a predetermined language and performs the manual report printing in a language for the log-in user.

  • Patent number: 9241755
    Abstract: Various embodiments of a capsule polishing device include a resistive-heating element including an electrically resistive, superelastic wire forming a loop between first and second ends of the superelastic wire. The first and second ends of the loop may at least partially extend from a planar face defined by the loop, to an insulating portion. In some embodiments, the capsule polishing device may be configured to perform active capsule polishing through a combination of hyperthermia of LECs and mechanical abrasion of the capsule surface. In some embodiments, at least a side and end portion of the loop of the capsule polishing device may be shaped to follow a contour of the capsule bag. The loop may be heated to approximately 40 to 47 degrees Celsius to destroy LECs (other temperatures are also possible). In some embodiments, the loop may include a roughened surface to increase mechanical abrasion.

  • Publication number: 20150141968
    Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.
