Instaref R-20

Handheld portable auto refractometer for screening refractive errors

Accuracy within ± 0.25 dioptre

With Shack Hartmann aberrometry technology, Instaref provides accurate and reliable refractive error values. A clinical study on 122 patients against a predicate desktop AR device Topcon 8900 shows an accuracy to within +/- 0.25D.

Intuitive positioning of the device ensures unmatched repeatability

The infrared imaging feedback ensures that the device is always centered on the pupil. The built-in audible tilt warning system ensures high accuracy of cylindrical values as well.

Fast and easy reading

In less than three seconds, you will have three quick and accurate readings and a final average value. The results can also  be printed using Bluetooth enabled wireless printers instantly.
