The official marketing brochure for the Reichert RK-600 is merely two pages– one of which is mostly a title page containing a large image of the device’s screen. In fact all the official marketing information for the RK-600 contained less than 350 words in total. This is matter of fact because the RK600 is simple, basic, and minimal (at least for a desktop Autorefractor). The entire instrument is merely a forehead rest, joystick, and an LCD screen with 5 buttons that control just about everything you’d expect. We’d call that quite minimal for auto refractor terms; the RK-600 also looks pretty neat resembling some sort of geometric robot/space shuttle which we always give bonus points for. However when it comes to the nuts and bolts, the RK600 does everything you’d expect from an ARK, including auto measurements, base curve of contact lenses, IOL modes, and PD measurements all with effortless accuracy and speed. Its large LCD screen is quite advanced for its release date, offering on screen instructions and complete navigation all without having to look away. The RK-600 feels like a unit that fits well between the older CRT screened units, and the brand new touch screen models, all while being in a very fair market state (price).
OUR TAKE: A very sleek and minimal exterior design with a mid-decade LCD screen that impresses. Accurate and robust despite a few bells and whistles found on other similar units.
#1. Sleek + Minimal
We give bonus points for ARKs that resemble spaceships, and we think the RK-600 qualifies. Most pre-touch-screen instruments feature loads of buttons which control one specific software feature of navigation. The RK-600 has only four buttons; all you need when the sleek LCD screen can be navigated all from the operators steady sight.
No, the RK-600 does not have a robotic motorized optical head (that does all the alignment work for you) such that the Zeiss HARK 599 does, however it’s software will intuitively help you align the proper corneal position, and then automatically obtain up to 10 measurements per eye– all without you pressing a button. The joystick is there for you (yourself) to help the unit get on the right track, and we don’t mind when we use it; it feels almost like an arcade game. The unit of course has a manual mode as well which keeps the software from interfering with your subjective alignment.
#3. Peripheral Ks
The only reason we can really think to still have a manual keratometer is the granting ability of recording keratometric values outside the very center of the cornea. But with the RK600, that’s no longer necessary as its built-in peripheral keratometry mode provides accurate measurements for examining oblique astigmatism as well as for determining the best fit for contact lenses. The Reichert can be used to make a series of measurements at a 30 ̊ angle from the eye’s center, along the attentive meridians. Readings for the corneal astigmatism axis and corneal eccentricity (E) are automatically included on the printout.
#4. Thermal, Auto-Cut Printer
Most Autorefractors have a thermal printer, and the RK600 is no exception. But not every unit has an auto-cut printer; no more tearing off uneven chewed-up bits of printouts and sticking them in the chart. The RK600 printout cuts clean, every time.
It does have RS-232 connections outputs, and with Reichert cable P/N 15030-401 the unit should integrate with most EHR platforms.
