| Features |
| Easier, more comfortable operation |
| The RK-F1 replaces the conventional joystick with a trackball and roller tandem that eases hand movement during manual alignment. And, once the examinee's pupil is visible in the monitor, you just press the Start button to initiate-and complete-measurements of refraction and keratometry.
|
| |
| More efficient exam procedures |
| From the first part of the process to the last, the RK-F1 simply does things better. Its measurement head covers an exceptionally wide area, thus speeding up the auto-alignment process, and even the built-in printer delivers your printout faster than ever.
|
| |
| Increased measurement reliability |
| By simplifying operation, Canon's fully automated measurement technology takes on a greater share of the workload and increases the reliability of measurement data. What's more, the unit's monitor employs a deep focal point, which makes it easier for you to tell whether an examinee's eyelashes are obstructing measurement.
|
| |
| Refraction and Keratometry |
| In terms of reliability and precision, the RK-F1's performance is second to none. For refraction, its dioptric 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 5.5mm to 10.0mm. 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, the RK-F1 also features a small minimum pupil size requirement and an automatic fogging system with color picture target.
|
| |
| Corneal periphery measurement |
| 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 degree angle from the eye's center, along the attentive meridians. Full auto-alignment 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.
|
| |
| Retroillumination |
| Through retroillumination, the RK-F1 brings you an extremely detailed view of the eye that's particularly useful for identifying cataracts, vitreous opacity, scars, and other serious eye problems. Dust or scratches on the examinee's contact lens are also clearly visible in this mode. The RK-F1 stores up to two images, which can be selected and displayed on the monitor at a magnified size for observation.
|
| |
| Diameter measurement |
| 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.
|
| |
| Ergonomic controls and more |
| 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 improvement 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 measurement or in other situations where the examinee's eyelid needs to be lifted.
|
| |
| Motorized chin rest1_800_755_5919 |
| 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 a pair of keys located on the unit's operation panel.
|
| |
| A great fit in any exam area |
| The RK-F1 features a stylish, original body design that does more than just change the notion of
what optometric equipment can look like. Because its measurement head is the only part that moves, examinees are free to place their hands, eyeglasses, or belongings next to the unit while their eyes are being checked, a nice benefit especially if exam space is limited. Furthermore, the power cord connects to the bottom of the unit, which contributes to tidy installation.
