  • Publication number: 20190110890
    Abstract: Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the piggyback lens can be configured to improve or reduce optical errors at the location on the peripheral retina.

    Abstract: In some embodiments, a microsurgical instrument includes a trocar having a rigid, hollow shaft formed with a lumen extending from a proximal end to a distal end of the shaft. The distal end of the shaft may be shaped for tissue penetration. The instrument may further include a composite microcannula slidably engaged with the trocar in the lumen. The microcannula includes a light guide and a flexible hollow tube having an outer diameter less than an inner diameter of the lumen in the trocar. Other embodiments include placing the microcannula in the lumen of the trocar, illuminating the end of the trocar by illuminating the end of the microcannula, advancing the trocar from a selected entry point on an eye into a selected structure in the eye, and extending the illuminated end of the microcannula from the trocar into the selected structure.

    Abstract: An ophthalmic surgical laser system includes: a laser that produces a pulsed laser beam having a pulse energy and pulse repetition rate; a high frequency fast scanner; an XY-scan device; a Z-scan device; and a controller. The controller controls the high frequency scanner to produce a scan line having a scan width; controls the XY-scan device and the Z-scan device to carry out of first sweep of the scan line in a first sweep direction and to carry out a second sweep of the scan line in a second sweep direction that is not parallel to the first sweep direction thereby defining an overlap region. At least one of the pulse energy, repetition rate, XY-scan speed, and the scan width is varied so as to accelerate the cutting speed and reduce the exposure of ophthalmic tissue in the overlap region to multiple exposures of laser pulses configured to modify ophthalmic tissue.

  • Publication number: 20190110931
    Abstract: A heat transfer device particularly structured for application of thermal therapy from a contact surface to a human ear. A device may be passive (pre-cooled), active (thermoelectrically active), or include elements of both. A device may be structured to apply thermal treatment from a contact surface of a contact cavity only to a localized posterior area relative to the circumference of an ear. Preferably, a device provides an uninterrupted opening extending in a line-of-sight between an ear canal and the local environment. A device may include both of a contact cavity and a bulk cavity, with heat transfer media disposed in each cavity. Typically, a bulk cavity holds at least twice the media volume contained in a contact cavity. The cavities may be disposed in fluid communication, or separated by a barrier to permit only thermal communication there-between. When a barrier is present, a device may include different heat transfer media in each cavity.
