Nidek ARK-1a Auto ref-keratometer

The ARK-1a is a multimodality device that includes autorefraction and keratometry.
This automated instrument measures with objective accuracy and
features accommodation testing and retro-illumination.
Super Luminescent Diode (SLD) technology allows for
accurate measurements on patients with cataracts, corneal opacities,
IOLs, and post LASIK procedures.
The ARK-1a also utilizes a multiple pupil zone imaging method combined with
rotary prism technology and an auto alignment Eye Tracking System to
ensure consistent, accurate, reliable and repeatable data.
