What is everyone else using...We do have a Zeiss Clarus but isn't cleared for all studies..

Thanks

We also still use our FF4 for the majority of our studies, but also have an California, and Clarus. I have tried to get my Clarus certified for as many trials as I can that will allow me to substitute it for 7 field colors. I still love my Zeiss but know even though it is built like a tank, it will fail eventually. Several studies still require "normal" color fundus photos, so will not allow us to replace them with our Optos, but some are allowing us to substitute Clarus colors.]]> Thu, 22 Jul 2021 21:35:25 GMT https://www.opsweb.org/forums/posts.aspx?topic=1625021 https://www.opsweb.org/forums/posts.aspx?topic=1625021 Thu, 22 Jul 2021 21:40:42 GMT https://www.opsweb.org/forums/posts.aspx?topic=1626005 https://www.opsweb.org/forums/posts.aspx?topic=1626005
I find it interesting the Clarus is being accepted in the same form for color imaging, because it's a cSLO by Zeiss's own words. Reading through their paperwork on the system it seems like the process is very similar in capture method as the Optos California or the Heidelberg Spectralis HRA+OCT systems, in that they use very specific wavelengths to create an IRGB image, and combining them with the right intensity and pulse frequency gives the appearance of a white light. The after image a patient sees from the Clarus however, is in line with the after image color a patient sees from the Optos or Heidelberg Engineering systems, and not the after image color that you experience from the flash of light from a traditional color fundus camera.]]> Thu, 29 Jul 2021 14:15:36 GMT https://www.opsweb.org/forums/posts.aspx?topic=1626006 https://www.opsweb.org/forums/posts.aspx?topic=1626006
