Of all the pretest instrumentation we review here, I think it’s fair to say that we score devices that look good far better than those that resemble a 1980’s slot machine. Of course what looks good is completely subjective and perhaps even irrelevant if it works correctly– we still just admire the brands that created something sleek even by today’s standards. The Nikon Speedy-K may not be today’s chic but it still looks pleasant despite it’s years in service. It’s footprint is rather slim thanks to a smooth-rounded optical head that pitches slightly upward in an attractive stance, and it’s monitor is still quite large despite its compact body. We do question the decision to build the forehead rest of industrial-like steel, and why the folks at Nikon didn’t provide a comfortable forehead rest from a reasonable material, yet it doesn’t harm the instrument’s contemporary aesthetic. Under the hood, the Speedy-K is equipped with a ‘turbo-like’ thingy which speeds-up refractive measurements by shortening the fogging mechanism and increasing the shutter speed; think of it like a ‘sport’ mode for your SUV. Named after this mechanism, Nikon (back in-the-day) created an ARK that was indeed quick. . . even if it has now been copied by the competition. Under quick-mode, the Speedy-K will pull refractive (and keratometric) measurements within .01 seconds and perform continuous measurements producing an average automatically. Furthermore, Nikon’s speed-demon will store up to 100 patient’s refractive and keratometric results, as well as offer fixation intensity control, wireless data transfer, a video jack, and more.
OUR TAKE: Sleek and neatly styled proportions; measurement times could be quicker and it’s frame could be made of something less crude.
The Tangential method measures four peripheral points in 25 degree direction concurrently, dramatically saving time. Refraction, Keratometry Center and Peripheral data are all taken simultaneously, in a 0.45 second reading.
Measure Refraction and Keratometry data continuously and automatically in a 0.35 seconds per reading.
For Keratometry, Speedy-K boasts a corneal radius curvature range of 5 – 11 mm and a corneal astigmatism range of up to 12D. For refractions, its spherical range is from -18D to +23D, while its cylindrical range is up to 12D.
The light intensity of the fixation chart can be reduced for patients whose eyes are overly sensitive to light. In addition, the improved Tree target is easy to see, and is familiar, even for children. The periphery of the target is slightly blurred so that the patient will focus easily on the center of the target.
Speedy-K also permits measurement of contact lens curvatures by using a dedicated contact lens holder.
It will depend on your EHR company, and/or your current EHR set-up. The Speedy-K does have an RS-232 connection– it will depend on whether your EHR company has written the proper gateway.
Back in the day when the Speedy-K was first released, it was considerably quick compared to the competition. These days, brand-new auto refractors are indeed faster.
It does. The Speedy-K has a “turbo-continuous” mode which decreases the duration of a measurement, and automatically captures it.
You bet. The Speedy-K does offer the ability to connect an external monitor for viewing.
