The RESIGHT Fundus Viewing System
The surgical field at a glance Hands-free focusing
•Excellent, clear view of the fundus
•The surgical field at a glance: Varioscope
optics ensure that OPMI LUMERA 700
always stays in the same focal plane
•Hands-free focusing with the wireless foot
control panel
•Fast, convenient and sterile access to a
second lens due to the innovative aspheric
lens turret
•Automatic inversion of microscope and
video imagewhen using RESIGHT 700,
Invertertube E and MediLive Trio Eye video
cameras
A smooth workflow and first-class ZEISS optics
Always the right orientation
