PASCAL Synthesis, Pattern Scanning Laser
  • Description
  • PASCAL® scanning laser technology revolutionized laser therapy. The PASCAL® Synthesis ™ with new patterns, an improved interface, a 3D controller and a versatile ergonomic table, once again redefines pattern laser therapy. The PASCAL® Synthesis™ dual-port pattern scanning retinal laser is available in 532 nm (Green) or 577 nm (Yellow) or for the TwinStar 577/638 nm (Yellow/Red) wavelength. With pricing similar to a premium single spot laser system, PASCAL Synthesis will allow fast and effective treatment of retinal disorders using clinically proven pattern-generating technology.

    In October 2019, introduction of a totally re-engineered slit lamp, the SL-PA04, which comes with these new functions:


    • LED Illumination – The new LED illumination delivers bright, sharp and homogeneous slit beam that improves subtle detail observation during treatment.
    • Incorporated Micromanipulator – Comfortably located on the back panel of the slit lamp body, the micromanipulator allows for precise location of the aiming beam and treatment beams without movement of the patient’s eye.
    • Power Adjustment Knob – The power adjustment knob, also located on the back panel, permits quick and precise adjustment of the laser treatment power.
    • CB-8 Binocular System – The new and improved CB-8 binocular system provides enhanced vision without flare and increased viewing comfort. The 10x eyepieces and 8-degree angle facilitates fusion, especially in users with shorter PD. The smooth movement of the PD adjustment makes it easier to find a comfortable pupillary range.
    • Gooseneck Fixation Target – The new gooseneck target adds flexibility to the managing of the patient’s fixation during treatment.
    • Magnification Configuration – New magnification configuration improves visibility of the treatment area with the different fundus lenses. The 5x; 8x; 13x 20x and 32x magnification grouping allows for a wider and more comfortable view.
