Canon RK-F1 Full Auto Ref-Keratometer: Advancing Efficiency and Comfort in Eye Measurement

The Canon RK-F1 Full Auto Ref-Keratometer redefines the operation of ophthalmic equipment, providing a more comfortable and easier experience for both the operator and the patient. By replacing the conventional joystick, the RK-F1 adopts a trackball and roller tandem system that facilitates manual movements during alignment. Once the patient's pupil is visible on the monitor, simply press the Start button to initiate and complete the measurements of refraction and keratometry. This intuitive design not only simplifies the operation but also increases the accuracy of the exams.

The RK-F1 enhances the efficiency of exams from start to finish. The measurement head covers an exceptionally wide area, accelerating the auto-alignment process. Additionally, the built-in printer delivers printouts faster than ever. This speed does not compromise precision; rather, the simplification of operational procedures ensures that measurements are conducted more quickly and reliably.

By simplifying operation, Canon's fully automated measurement technology takes on a greater share of the workload, increasing the reliability of measurement data. The RK-F1's monitor employs a deep focal point, making it easier to identify obstructions, such as the patient's eyelashes, that may interfere with the measurement. With over a decade of setting standards in ophthalmic and optometric technology, Canon, with the RK-F1, continues to lead technological advancement, offering a device that not only improves exam accuracy but also reduces overall procedure time.

The RK-F1 simplifies the standard measurement procedure to an unprecedented degree, performing all operations in a single step. With the simple 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 also, in combination with improved measurement technology, to enhance the accuracy and reliability of eye exams. Easier to use, more efficient, and more precise, the Canon RK-F1 represents yet another significant advancement in optometric technology.

With the RK-F1, Canon reaffirms its commitment to continuous innovation in ophthalmic technology. The combination of simplified operation with greater measurement precision makes this device an ideal choice for professionals seeking efficiency and reliability. The ease of use and reduced exam time allow professionals to attend to more patients without compromising diagnostic quality. Thus, the Canon RK-F1 Full Auto Ref-Keratometer not only improves clinical practice but also elevates the standard of eye care.

In terms of reliability and precision, the performance of the RK-F1 is unmatched. For refraction, its dioptric measurement range of -30D to +22D is among the widest available, allowing for a more detailed examination of severe myopia and other conditions. In 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 corneal radius, residual astigmatism, and pupil distance. To further ensure data reliability, the RK-F1 also features a small minimum pupil size requirement and an automatic fogging system with a color picture target.

Through retroillumination, the RK-F1 provides an extremely detailed view of the eye, which is 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.

The peripheral keratometry mode offers accurate measurements for examining oblique astigmatism and determining the best fit for contact lenses. 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. Full auto-alignment technology streamlines this procedure, as the operator only needs to 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 are automatically included in 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 employs its intelligent auto-alignment feature to capture an optimum still image of the eye. It then derives its data from the captured image. This process overcomes the obstacles posed by eye movement to obtaining precise measurements.
