Automatic refractometers and auto ref/keratometers measure the refractive error of the eye objectively in seconds, and the keratometer models also measure the curvature of the cornea. They give a fast, repeatable starting point for the subjective refraction and for contact lens fitting. The range below consists of the TW-9100K, the TW-9200K with touch screen and the ARK-4000. Not sure which one fits the way your practice works? Tell us how many patients you see and what you need to measure, and we will advise you and send a personal quote with delivery to your practice.
