Zeiss Humphrey 597 K Autorefractor / Keratometer

The Humphrey 597 provides refinement of sphere, cylinder and axis for true optimization. In addition, near vision, glare, complete subjective testing and special targets for children and patients with reading difficulties allow the practitioner to test the widest range of patients. Precise keratometric readings are performed quickly and easily during the refraction process. (NOTE: The Model 597 provides only refraction, not glare testing nor K readings. The Model 597K adds K readings. The Model 599 adds full subjective refinement, low contrast acuity charts and glare testing).
