A NEW DIMENSION IN VISUALISATION
Maria-Christine Fischer, Lecturer in Ophthalmology
he new ophthalmic operating
microscope Zeiss Lumera 700 was
T purchased with an Animal Care
Trust (ACT) grant and has provided a vast
amount of benefits, not only to our patients,
but also to research, veterinary education,
and specialist training.
The operating microscope provides us
with an exceptional surgical experience as
its technology offers a greater depth and
width in the field of view and the Stereo
Coaxial Illumination technology allows
us to visualise every anatomic detail with
perfect clarity. This is a big advantage for
routine procedures contributing to shorter
anaesthetic times and has proven to be
especially helpful when performing lens
removal surgery in small exotic eyes.
Together with the new Alexos 3 Phaco
system from An-Vision, also funded by
the ACT, it is now possible to perform
microincisional cataract surgery in even
smaller exotic eyes.
Another advantageous feature
of Zeiss Lumera 700 is the video
screening. It has enabled an improved
communication and interaction with the Use of the operating microscope at RVC Equine
