The 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 fully automated when aligning, tracking, and focusing on the patient 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.
