    It is recommended to use VISULAS green with laser endoprobes by ZEISS 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 106 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. This will enable the proper output power indicated on the graphical user interface of the control panel.
