This document contains a series of slides comparing the RESIGHT Fundus Viewing System from Carl Zeiss Meditec AG to other fundus viewing systems such as those from Oculus, Topcon, and Volk. The RESIGHT System is highlighted as having excellent Zeiss optics, constant distance to the patient's cornea during focusing, a lens turret for fast access to a second lens, and efficient workflow when used with the motorized Invertertube and MediLive Trio Eye video cameras. It is also noted as having a stable working height and only requiring the lens holder and lenses to be sterilized.

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 image when using RESIGHT 700,
Invertertube E and MediLive Trio Eye video
cameras
A smooth workflow and first-class ZEISS optics
Always the right orientation

• Higher investment costs
• All optical components are sterilized
• Reduction of optical quality due to sterilization
process
• Lower investment costs
• Only aspheric lenses are sterilized
• Varioscope focusing lens remains excellent
optical quality
