    Use the laser endoscope only once. Resterilization is not permitted. It is recommended to use VISULAS green with ZEISS laser endoprobes as the efficacy and safety of this combination has been demonstrated. As a rule, VISULAS green is prepared for use with commercial endoprobes from third party suppliers which have been approved for intraocular treatment.
  • Page 123 Light transmission of laser endoprobes may vary from supplier to supplier. If you change your laser endoprobe supplier, make sure that your local ZEISS service engineer measures and stores the transmission of the new laser endoprobe in the system. This will enable the proper output power indicated on the graphical user interface of the control panel.
