Sensitive scalpel among secondary cataract lasers
The VISULAS® YAG III from Carl Zeiss is a milestone in the development of practice-oriented photodisruption 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 as well as IOL polishing.
Legendary ZEISS optics
For decades Carl Zeiss Meditec has been developing high-quality therapeutic lasers featuring outstanding precision and legendary optics from ZEISS. Perfectly integrated laser slit lamps guarantee superior slit lamp image quality, which is an important requirement for reproducible clinical results.
Gentle laser treatment
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 to the patient using a minimum of laser energy.
Variable focus shift
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 laser 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 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.
