Nidek ark 1s Autorefactor Keratometer

NIDEK ARK 1s is a multimodality device that includes autorefraction/keratometry/glare testing mixtures. This automatic tool measures with goal accuracy and features accommodation testing and retro-illumination. The lodging can help to detect early presbyopia, latent hyperopia, and children with reading difficulty. The retro-illumination advantages patients in viewing and understanding their cataracts. Super Luminescent Diode (SLD) makes it feasible to accurately quantify patients with cataracts, corneal opacities, IOLs, and article LASIK procedures.

The ARK-1s offers visual acuity (VA) measurement. A glare source is illuminated together with the chart and the warmth VA can be quantified.

NIDEK ARK 1s helps you quickly assess and document vision loss on your patients. It's one of the initial autorefractor/keratometers that has glare testing accessible.

The NIDEK ARK 1s was used only after for research. It's essentially brand new and still under warranty. It'll be shipped in the original packing box, comes with the manual, testing eye, power cable and computer cable (an extra thing).
