The ZEISS VISULAS lll Yag Laser is a milestone in the development of practice-oriented photodisruption laser systems. It brings together latest generation optical experience and technological excellence to provide maximum ease of use with the least possible amount of patient stress.

The laser is used for applications like posterior capsulotomy and iridotomy as well as IOL polishing.

Legendary ZEISS optics

For decades ZEISS has developed high-quality therapeutic lasers featuring exceptional precision and legendary optics. Perfectly integrated laser slit lamps guarantee superior image quality in order to deliver reproducible clinical results.

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.

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.
