OPERATING INSTRUCTIONS: JUST PRESS START

B E Y O N D A U T O - A L I G N M E N T

■ Easier, more comfortable operationThe RK-F1 replaces the conventional joystick with a trackball and rollertandem that eases hand movement during manual alignment. And, oncethe examinee's pupil is visible in the monitor, you just press the Start buttonto initiate—and complete—measurements of refraction and keratometry.

■ More efficient exam proceduresFrom the first part of the process to the last, the RK-F1 simply does thingsbetter. Its measurement head covers an exceptionally wide area, thusspeeding up the auto-alignment process, and even the built-in printerdelivers your printout faster than ever.

■ Increased measurement reliabilityBy simplifying operation, Canon's fully automated measurement technologytakes on a greater share of the workload and increases the reliability ofmeasurement data. What's more, the unit's monitor employs a deep focalpoint, which makes it easier for you to tell whether an examinee'seyelashes are obstructing measurement.

R e l i a b l e m e a s u r e m e n t s

Refraction and keratometryIn terms of reliability andprecision, the RK-F1'sperformance is second tonone. For refraction, itsdioptric measurement rangeof -30D to +22D is amongthe widest available, which

allows you to better examine strong myopia and otherconditions. And for keratometry, the radius of curvatureextends from 5.5mm to 10.0mm. As refraction andkeratometry are measured in the same sequence, thefinal printout includes all the results together: SPH, CYL,AX, central radius of the cornea, residual astigmatism,and pupil distance. To further ensure the reliability ofyour data, the RK-F1 also features a small minimumpupil size requirement and an automatic fogging systemwith color picture target.

RetroilluminationThrough retroillumination, the RK-F1 brings you anextremely detailed view of the eye that's particularly

useful for identifyingcataracts, vitreous opacity,scars, and other serious eyeproblems. Dust or scratcheson the examinee's contactlens are also clearly visiblein this mode. The RK-F1stores up to two images,which can be selected anddisplayed on the monitor at a magnif ied size forobservation.

Ergonomic controls and more

The operation panel of theRK-F1 offers an unmatchedlevel of operator comfort atevery stage of the process.First of all, manual alignmentcan be done using your

fingertips alone, thanks to the unique trackball androller configuration—a major improvement overconventional joystick operation. Also, the easy-to-presscontrol keys are grouped together to simplify access tothe unit's various functions, which include vertexdistance switching, measurement mode switching, anddisplay of data stored in memory. The layout of theoperation panel allows comfortable use from either aseated or standing position. In addition, the unit's bodydesign gives you unrestricted access to the eye—animportant feature when long eyelashes obstructmeasurement or in other situations where theexaminee's eyelid needs to be lifted.

A great fit in any exam areaThe RK-F1 features a stylish, original body designthat does more than just change the not ion of

what optometric equipmentcan look l ike. Because i tsmeasurement head is the onlypart that moves, examineesare free to place their hands,eyeglasses, or belongingsnext to the unit while theireyes are being checked—anice benefit especially if examspace is limited. Furthermore,the power cord connects to thebottom of the unit, whichcontributes to tidy installation.

Corneal periphery measurement

The peripheral keratometry mode provides accuratemeasurements for examining oblique astigmatism as wellas for determining the best fit for a contact lens. The RK-F1 can be used to make a series of measurements at a30˚ angle from the eye's center, along the attentivemeridians. Full auto-alignment technology streamlinesthis procedure, as all the operator needs to do is pressthe Start button to confirm that the eye is properly fixatedon each measurement point. Readings for the cornealastigmatism axis and corneal eccentricity (E) areautomatically included on the printout.

Diameter measurementDiameter measurements ofthe cornea or pupil, or of acontact lens being wornduring the eye exam, areeasy to acquire with the RK-F1. To ensure the accu-racy of measurements, the

unit first deploys its intelligent auto-alignment feature tocapture an optimum still image of the eye. Next, itderives its data from the captured image. This processovercomes the obstacles posed to obtaining precisemeasurements by eye movement.

Motorized chin restA motorized chin rest makes it easy to adjust the RK-F1 when beginning the eye exam. The chin rest

can be moved up and downto match the examinee'sheight using a pair of keyslocated on the unit 'soperation panel.

Universal power supplyThe RK-F1 comes complete with an automatic voltageswitching capability, to facilitate setup in practically anyoperating environment. And, because it conforms tointernationally recognized UL standards for electricalsafety, you can be assured of safe, secure use of theunit at all times.

One Touch Does ItAll—From AutomaticAlignment toPrecision Output.

For over a decade, Canon has continuallyset the standard for innovation inophthalmic and optometric technology. Andnow, with the RK-F1 Full Auto Ref-Keratometer, we're ready to do it again.That's because the RK-F1 simplifies thestandard measurement procedure to anunprecedented degree—all operations injust one step. With a press of the Startbutton, the RK-F1 automatically completesthe entire series of steps for both eyes:alignment, measurement, and printout. Thisimproved process promises not only toreduce overall exam time, but—incombination with improved measurementtechnology—will raise the accuracy andreliability of eye exams as well. Easier touse, more efficient, more precise: TheCanon RK-F1 represents yet anotherbreakthrough in optometric technology.
