New Canon RK-F2 Full Auto Ref-Keratometer features improved operability, facilitates fast, easy examinations
March 28, 2012
TOKYO, March 28, 2012 – Canon Inc. and Canon Marketing Japan Inc. announced today the introduction in Japan of the
new RK-F2 Full Auto Ref-Keratometer, an eyecare device that automatically measures the refraction and radius of curvature of the cornea.
Intended for use in hospitals, ophthalmology clinics and eyeglasses stores, the RK-F2 offers greatly enhanced operability through
its 5.7-inch tilting LCD screen and compact, lightweight body design.
The RK-F2 Full Auto Ref-Keratometer is capable of automatically measuring not only the refraction and radius of curvature of
the cornea, but also such information as the refractive condition of short-sighted, far-sighted and astigmatic eyes, and the
corneal curvature, which is important for determining the best fit for eyeglasses and contact lenses. Inheriting the same high
performance as its predecessor, the RK-F1 Full Auto Ref-Keratometer (released in June 2001), the RK-F2 allows operators to easily
examine patients with small pupil sizes or suffering from ocular conditions.
Incorporating Canon’s proprietary auto-alignment technology, the RK-F2 makes possible the fast, accurate and fully automatic
examination of both eyes. Once proper alignment has been established for one eye with a portion of the pupil displayed on the monitor,
a single push of the start button enables the device to instantly detect the patient’s eye and automatically begins a continuous
series of procedures, beginning with the measurement of each eye in succession, through to the printing out of results.
The RK-F2’s fine auto-alignment drive technology is capable of quickly and accurately detecting the placement of the corneal apex,
even for patients who have trouble keeping their eyes stable.
Requiring a pupil diameter of just 2 mm, the RK-F2 even facilitates measurement for eyes that have a small pupil diameter
while retro-illumination provides a detailed view of eyes, which can be helpful for identifying cataracts and other serious
Featuring a redesigned drive system, Canon’s compact, lightweight RK-F2 realizes a smaller footprint and facilitates a smooth
measurement process. The 5.7-inch color LCD monitor, capable of tilting 40°, enables operators to easily confirm measurements
while either sitting or standing. Furthermore, the design of the measurement screen provides increased visibility to reduce the
occurrence of measurement errors. Other features contributing to enhanced operability include a fine control mode with a motorized
omni-directional joystick enabling fine focus adjustment, and a tracking mode that automatically adjusts the device’s working distance
during measurement. In addition to RS-232C output, which was also offered by its predecessor, the RF-K2’s improved interface supports
output through an LAN to facilitate connectivity with such external systems as examination and electronic health record systems.
Canon will be displaying the new RF-K2 at the company’s booth during the 116th Annual Meeting of the
Japanese Ophthalmological Society, which will be held at the Tokyo International Forum from April 5 to 8, 2012.
The Canon RK-F2 Full Auto Ref-Keratometer will be available in Japan from June 1, 2012, priced at ¥2.7 million (excluding tax).
Canon has set initial production at 100 units per month.
