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 each eye.
Selectable Measurement Modes
The three-dimensional tracking system of the RK-F2 features a wide range of movement, so that the examinee's 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 button and the ref-keratometer automatically aligns and measures both eyes. For added flexibility, Auto and Manual measurement modes are included.
Small Pupil Size
At 2 mm, the small pupil mode helps contribute to an efficient screening and is useful when a patient's pupils are difficult to dilate. The short reaching distance between the patient and operator allows closer personal interaction and easy access to the patient's eyes.
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.
Corneal Periphery Measurement
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 eye's center along the attentive meridians.
