| Comment |
ARK-1s Autorefractor & Keratometer is a multimodality device that includes autorefraction and keratometry plus glare testing. This automated instrument measures with objective accuracy and features accommodation testing and retro illumination. Super Luminescent Diode (SLD) technology makes it possible to accurately measure patients with cataracts, corneal opacities, IOLs, and post LASIK procedures. The ARK-1s also utilizes a multiple pupil zone imaging method combined with rotary prism technology and an auto alignment Eye Tracking System to ensure consistent, accurate, reliable and repeatable data.
