The VISULAS® YAG III from Carl Zeiss is a milestone in the development of practice-oriented photo disruption laser systems. It brings together latest generation optical experience and technological excellence and provides maximum ease of use with the lowest possible amount of patient stress. The VISULAS YAG III is used for applications like posterior capsulotomy and iridotomy.

The VISULAS YAG III focuses the optimum amount of laser energy directly to the target thanks to its Super-Gaussian beam profile. It therefore requires less energy to achieve the optical breakdown, as little as 2.5 mJ in air. The result: high-precision treatment of the patient’s eye using a minimum of laser energy.

Depending on the procedure, the focal point of the aiming beam is set precisely and reproducibly before, behind or directly at the focal point of the disruption laser.
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 ensures a high degree of aiming accuracy. Astigmatic distortions can be identified clearly. The selected energy level can be corrected accordingly prior to the laser application.

The VISULAS® YAG III offers an outstanding range of diagnostic possibilities and permits high-precision examinations to be carried out immediately before and after treatment – without any need to move the patient. The extensive selection of optional accessories perfectly completes the laser’s wide range of functions.
