  • Page 2: Notes

    IEC 60601-1. If the CA-200F corneal analyser is installed in rooms for medical use and is not connected to a computer, there is no need to use an insulated transformer. If a printer is connected directly to the CA-200F corneal analyser, it must be powered by an insulated transformer in accordance with IEC 60601-1.

  • Page 3: Intended Use

    CA-200F Corneal Analyser - Rev. 7 16/01/2012 INTENDED USE Use: CA-200F is a corneal analyser with integrated pupillograph. The instrument acquires images of the cornea and analyses its topography. The software selects the image with the best focus out of a sequence of images.

  • Page 4: Introduction

    This instrument also allows you to simulate contact lenses and view the 3D map to analyze the wavefront corneal aberrations. Notes: This manual describes the TOPCON CA-200F corneal analyser, including the functions, basic operations, instrument cleaning, and instrument storage. For best use of the instrument, carefully read the instructions provided.
