Nidek ARK-2000 Autorefractor Keratometer Fast (less than 1 sec) and Accurate
This lightly used auto-refractor / auto-keratometer accurately and simultaneously measures the refraction and keratometer in less than one second! It is a great solution for auto-refraction, pre-refraction, and contact lens fitting. It works great on small pupils and eyes with mild to moderate cataracts. Acquisition time for auto-refraction is less than 0.5 second, and auto-keratometry takes less than 0.1 second! This speed makes the ARK-2000 ideal for fidgety or uncooperative patients.
The unit can be set up for plus or minus cylinder at the press of a button. It can be configured to perform auto-refraction only, auto-keratometry only, or both at the same time.
Sphere and cylinder, axis, keratometry steep and flat powers (in diopters or millimeter radius), keratometry axis, and PD (pupillary distance) are all displayed on the integrated monitor, along with an eye image while the measurement is being taken. IOL compensation circuitry enables accurate results with post-cataract surgery patients. The unit can be used as a stand-alone, linked to a Nidek or Marco A-scan, or fully integrated with the Marco or Nidek Epic refraction system to give a complete refracting solution.
Readings can be read directly off the screen, transmitted automatically to the Epic refracting system (not included), or integrated to an EHR using a custom RS-232 interface (not included). Please note that this unit came from an Epic refracting system, and the printer was never used. It has a "printer error 4" which prevents paper printouts, but does not interfere with any of the other functions of the unit.
Also note that the apparent "lines" on the screen in the photos are not real, they are a photographic artifact. There are no lines or other defects on the screen of the unit.
