Nidek Tonoref II ARK/Tono

The Marco Tonoref II combines the technologies of autorefractor,
keratometer, and non-contact tonometer into one highly accurate,
space-saving device.
The Tonoref II presents several enhanced features such as a smaller footprint,
to save even more space, and a new exterior design, but most importantly,
the Tonoref II now uses SLD (Super Luminescent Diode)
and a highly sensitive CCD device to provide Zonal Ring-Image Technology.
This makes it possible to now accurately measure patients with cataracts,
corneal opacities, IOLs, and post LASIK.
