    Optimal Energy Focus

    Utilizing a Super-Gaussian beam profile, the VISULAS YAG III is able to focus the optimum amount of laser energy directly to the target. This results in high-precision treatment for the patient using a minimum amount of laser energy.

    Variable focus

    The focal point of the aiming beam is set precisely and reproducibly before, behind or directly at the focal point of the disruption laser.

    Fully integrated workplace

    The high-quality laser source of the VISULAS YAG III is perfectly integrated into the ZEISS laser slit lamp, which can also be used as a fully-equipped diagnostic slit lamp.

    the unique 4 point aiming beam

    Precision targeting

    The unique 4-point aiming beam ensures a high degree of aiming accuracy. Astigmatic distortions can be identified clearly and the selected energy level can be corrected accordingly prior to the laser application.
