More Information
This is a Nidek Tonoref II manufactured in 2008. This does very accurate auto refractions and keratometry readings, in addition to NCT readings that are usually within 2mm of a Goldman reading in my experience. I own 3 of these. That is how much I love these. This one has been lightly used in my Satellite office for the last 10 years and is in excellent condition and works perfectly. This instrument only gets used one day a week. It takes 3 readings per eye and averages them in about a second. The accuracy is such that refining with a subjective refraction typically results in no significant change at all.
