The RK-F2 automatically aligns, acquires the readings and then
moves over to the opposite eye to perform the same function using
the Full Auto mode. Alignment may also be performed using the Auto
setting, where only one eye is automatically examined, or using the
Manual setting. If the pupils have a diameter as small as 2 mm,
readings may still be acquired using the small pupil mode. Up to 10
measurements of Refractometry and Keratometry may be stored for
The three-dimensional tracking system of the RK-F2 features a wide
range of movement, so that the examinees pupil can be detected
easily. When in Full Auto mode, the unit is a one touch operation
for auto-refraction and curvature measurement in both eyes. Just
press the start and the ref-keratometer automatically aligns
and measures both eyes. For added flexibility, Auto and Manual
measurement modes are included.
At 2 mm, the small pupil mode helps contribute to an efficient
screening and is useful when a patients pupils are difficult to
dilate. The short reaching distance between the patient and
operator allows closer personal interaction and easy access to the
Using infrared retro-illumination, the RK-F2 provides a detailed
view of the eye which is helpful for identifying cataracts,
vitreous opacity, scars, and other serious eye problems.
The peripheral keratometry mode provides accurate measurements for
examining oblique astigmatisms and helps determine the best fit for
a contact lens. The RK-F2 can be used to make a series of
measurements at a 30 degree angle from the eyes center along the
The dioptric measurement range of -30D to +22D allows examination
of strong myopia or hyperopia. The astigmatic measurement range
extends from 0 to 10D. The radius of curvature extends from 5 to 10
mm (33.75D to 67.5D) for keratometry.
The compact design of the RK-F2 is designed to be operated either
sitting or standing, whichever is more comfortable for the
operator. Weighing a little more than 33 pounds, the lightweight
RK-F2 maximizes small work areas and comfortably fits on a Canon
instrument table (sold separately) with a Canon Full Auto Tonometer
or Canon Non-Mydriatic Retinal Camera (both sold separately).
Keeping the Canon machines next to one another can help expedite
the exam process.
Multi-Functional Color LCD
The 5.7 inch color LCD monitor tilts 40° making the RK-F2 easy to
use if the operator is sitting or standing. The clear LCD display
also includes multi-functional screen s allowing the operator
to switch menus as needed.
Aligning the patients eye is easy using the motorized
omni-directional joystick with a fine focus dial. All positioning
may be performed with one hand allowing the other hand to work with
the patient, if needed. The top of the joystick has the
start which can immediately be pressed once the patient is
The front-loaded, high speed built-in printer includes an auto
cutter making it simple to remove the print-out. The ECO setting
reduces the printing density and thereby conserves the paper
necessary for printing by up to 50% as compared to printing without
using the ECO setting. New paper rolls can easily be inserted
through the feeder.
