Marco, Nidek ARK-560A Auto Refractor
AMERICA North (USA-Canada-Mexico)
Highly Accurate Refractometer
The combination of the new measuring principle – Pupil Zone Imaging Method –
and unique technology – SLD – offers high accuracy and reliability in refraction measurement.
Pupil Zone Imaging Method
The NIDEK ARK-560A / 530A / 510A adopts the advanced Pupil Zone Imaging Method
for refraction measurement, which analyzes a wider area (Max. ø4 mm)
to obtain more reliable and realistic data that is closer to subjective refraction
SLD (Super Luminescent Diode)
The ARK-560A / 530A / 510A uses the SLD (Super Luminescent Diode)
and a highly sensitive CCD device for improved image quality.
The images with the SLD are sharper and clearer than those with the LED,
and the system offers greatly improved measurement capability even with dense cataracts and IOL implanted eyes.
The ARK-560A is the unique unit that provides visual acuity (VA) measurement.
This function enables a quick checkup of a patient’s refractive error by comparing
the subjective measurement with the objective measurement.
Even corrected visual acuity on near vision is measurable with easy operability,
which allows the proposal of progressive lens necessity
