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.
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.
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.
