  • Publication number: 20240108510
    Abstract: The present disclosure relates to an ophthalmological laser treatment system for treatment of tissue of an eye comprising an ophthalmological laser treatment device comprising a base station having a treatment laser source configured to generate a treatment laser beam, an arm and an application head, wherein the ophthalmological laser treatment system further comprises an ophthalmological patient interface with a cornea contacting element, and a sclera contacting element, wherein the cornea contacting element and the sclera contacting element define a rotationally asymmetric contact surface configured to contact the eye, wherein the ophthalmological patient interface comprises a through opening, which is configured to enable the treatment laser beam from the application head to pass through the ophthalmological patient interface to penetrate a target volume of tissue of the eye.

  • Patent number: 11717442
    Abstract: An ophthalmological device for surgical treatment of a cornea comprises a laser source, a focusing optical module, a scanner system, and an electronic circuit configured to control the scanner system to move the focus of the pulsed laser beam generated by the laser source to cut inside the cornea a lenticule and a venting channel which comprises an opening incision in a peripheral area of an exterior surface of the cornea, outside a perimeter of the lenticule from a top view perspective onto the cornea, and the venting channel connecting fluidically the posterior lenticule surface and/or the anterior lenticule surface to the opening incision, to enable venting of gas, produced by cutting the lenticule inside the cornea, through the opening incision to the exterior of the cornea.

  • Publication number: 20220192882
    Abstract: An ophthalmological device for treatment of a cornea comprises a laser source, a focusing optical module, a scanner system, and an electronic circuit. The electronic circuit is configured to control the scanner system to move the focal spot of the pulsed laser beam to generate a void volume inside the cornea by ablating cornea tissue with partially overlapping focal spots, whereby two or more focal spots partially overlap in direction of each of three dimensions of the void volume, and to move the focal spot inside the cornea to cut in the cornea a venting channel which connects fluidically the void volume to an escape area and enables venting of gas from the void volume through the venting channel to the escape area.

  • Publication number: 20220125632
    Abstract: An ophthalmological device for surgical treatment of a cornea comprises a laser source, a focusing optical module, a scanner system, and an electronic circuit configured to control the scanner system to move the focus of the pulsed laser beam generated by the laser source to cut inside the cornea a lenticule, an opening incision in an exterior surface of the cornea, and two access channels which connect the opening incision to the posterior lenticule surface and to the anterior lenticule surface to provide access for a surgical tool through the opening incision to the posterior lenticule surface and the anterior lenticule surface, respectively. The access channels are cut to overlap at least partially from a top view perspective onto the cornea.

  • Patent number: 4475557
    Abstract: The sphygmomanometer comprises an arm band having an inflatable cuff and a microphone, and an instrument connected to the arm band, which contains the necessary pneumatic and electronic elements. By means of the microphone and an amplifier, electrical signals corresponding to the Korotkoff sounds are generated during the decompression phase, and are applied to a discriminator. At the appearance of the first and the last signals, corresponding to the Korotkoff sounds, and each having an amplitude at least equal to a threshold value U.sub.R, the pressure in the cuff is measured and stored in memory as the systolic pressure and diastolic pressure respectively. During the decompression phase, the threshold value U.sub.R is first decreasing like a value proportional to the pressure in the cuff; then it increases at appearance of each signal corresponding to a Korotkoff sound and exceeding the instananeous value of the threshold level U.sub.R, after which it decreases again.
