The stylish, original body design 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.
The performance of the RK-F1 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. Through retroillumination it brings you an extremely detailed view of the eyes that's particularly useful for identifying cataracts, vitreous opacity, scars, and other serious eye problems.
The peripheral keratometry mode provides accurate measurements for examining oblique astigmatism as well as for determining the best fit for a contact lens. This machine can be used to make a series of measurements at an angle from the eye's centre, along the attentive meridians. Diameter measurement of the cornea or pupil, or a contact lens being worn during the eye exam, is also easy to acquire.
