RK - F1
One Touch Does It All
From Automatic Alignment to
Precision Output
For over a decade, Canon has continually set the standard for innovation in ophthalmic and optometric technology. And now, with the RK - F1 Full Auto Ref - Keratometer, we're ready to do it again. That's because the RK - F1 simplifies the standard measurement procedure to an unprecedented degree - all operations in just one step. With a press of the Start button, the RK - F1 automatically completes the entire series of steps for both eyes: alignment, measurement, and printout. This improved process promises not only to reduce overall exam time, but - in combination with improved measurement technology - will raise the accuracy and reliability of eye exam as well. Easier to use, more efficient, more precise: The Canon RK - F1 represents yet another breakthrough in optometric technology.
In terms of reliability and precision, the RK - F1' s performance is second to none. For refraction, its dioptic measurement range of - 30D to + 22D is among the widest available, which allows you to better examine strong myopia and other conditions. And for keratometry, the radius of curvature extends from 5.5 mm to 10.0 mm. As refraction and keratometry are measured in the same sequence, the final printout includes all the results together : SPH, CYL, AX, central radius of the cornea, residual astigmatism, and pupil distance. To further ensure the reliability of your data, thr RK - F1 also features a small minimum pupil size requirement and an automatic fogging system with color picture target.

FEATURES |
The operation panel of the RK - F1
offers an unmatched level of
operator comfort at every stage of
the process. First of all, manual
alignment can be done using your
fingertips alone, thanks to the
unique trackball and roller configuration - a major improve -
ment over conventional joystick operation. Also, the easy
to press control keys are grouped together to simplify
access to the unit's various functions, which include
vertex distance switching, measurement mode switching,
and display of data stored in memory. The layout of the
operation panel allows comfortable use from either a seated or standing position. In addition, the unit's body
design gives you unrestricted access to the eye - an
important feature when long eyelashes obstruct measure -
ment or in other situations where the examinee's eyelid needs to be lifted.
The peripheral keratometry
mode provides accurate
measurements for examining
oblique astigmatism as well
as for determining the best fit
for a contact lens.The RK - F1
can be used to make a series
of measurements at a 30° angle from the eye's center,
along the attentive meridians.
technology streamlines this procedure, as all the operator
needs to do is press the start button to confirm that the
eye is properly fixated on each measurement point.
Readings for the corneal astigmatism axis and corneal
eccentricity( E ) are automatically included on the printout.
Diameter measurements of the cornea or pupil, or of a
contact lens being worn during the eye exam, are easy to
acquire with the RK - F1. To
ensure the accuracy of
measurements, the unit first
deploys its intelligent auto -
alignment feature to capture
an optimum still image of the
eye. Next, it derives its data
from the captured image.
This process overcomes the obstacles posed to obtaining
precise measurements by eye movement.
A motorized chin rest makes it easy to adjust the
RK - F1 when beginning the eye
exam. The chin rest can be
moved up and down to match
the examinee's height using
two of the keys located on
the unit's operation panel.
