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.

Specification & Options

Features: Super Luminescent Diode (SLD) for sharper images compared to LED Accurate data even through many cataracts Eye Tracking system provides X-Y-Z tracking for superior alignment and focus Large pupil zone imaging method (up to 6mm diameter) Accommodation measurement Keratometry measurement with mire ring to reduce eyelid artifacts Retro illumination illustrates media opacity in both the cornea and lens Low contrast testing Visual acuity measurement with glare testing Subjective spherical refinement Near vision testing 6.5″ high-quality, full-color LCD screen High speed printer
