Nidek ARK 500A

The refurbished NIDEK MARCO ARK 500A
Auto Refractor Keratometer with
Built-in Printer is a highly accurate and
reliable device for measuring refraction and
keratometry in eye exams.
It incorporates advanced technology and
a unique measuring principle to
ensure precise and realistic measurements.

The Pupil Zone Imaging Method is
a new measuring principle used
in the ARK-560A.
It analyzes a wider area during refraction measurement,
resulting in more reliable and realistic data that
closely matches subjective refraction.
This method enhances the accuracy of
the measurements, providing eye care professionals with
valuable information for prescribing corrective lenses.

The device utilizes SLD (Super Luminescent Diode)
technology and a highly sensitive CCD device to
improve image quality.
Compared to LED-based devices,
the ARK-560A's SLD produces sharper and
clearer images.
This advanced technology enables
accurate measurements even in cases of
dense cataracts and eyes with
intraocular lenses (IOLs).

One unique feature of the ARK-560A is
its ability to measure visual acuity (VA).
This function allows for a quick check of
a patient's refractive error by
comparing subjective measurements with
objective measurements.
It also enables the measurement of
corrected visual acuity,
including near vision, providing valuable insights for
determining the need for progressive lenses.

Additionally, the ARK-500A is equipped with
a built-in printer, which offers the convenience of
instantly obtaining hard copies of measurement results.

By combining high accuracy,
advanced imaging technology, and
the capability to measure visual acuity,
the NIDEK MARCO ARK 500A Auto Refractor Keratometer with
Built-in Printer is an excellent choice for
eye care professionals seeking reliable and
efficient diagnostic tools for their practice.
