Nidek ARK-530A

The Marco Nidek ARK 530A is an Objective Automatic Refractor/Keratometer
featuring SLD (Super Luminescent Diode) making it possible
to now accurately measure patients with cataracts, corneal opacities, IOLs,
and post LASIK.
It also utilizes Zonal Ring Image Method combined with the most sensitive CCD.
The ARK-530A is a fully automated with aligning, tracking,
and focusing on the patients eye which insures the most reliable and repeatable data
for refractive and keratometry measurements.

The ARK-530A allows the operator to take peripheral keratometric measurements
including sagittal radius and eccentricity values used in corneal evaluations
for contact lens fitting and refractive surgery evaluations.
