Zeiss Humphrey Automatic Perimeter Field Analyzer HFA 3/830

Automatic perimeter Zeiss Humphrey Field Analyzer HFA 3/830, new. Includes table, printer, keyboard, mouse. The new Humphrey Field Analyzer 3 from Zeiss sets a new standard for efficient visual field testing. The new HFA3 offers gold-standard perimetry performance with technological advances such as automated trial lens correction designed to save time and reduce errors, with test results equal to and interchangeable with results from previous Humphrey perimeters. The HFA3 is the first perimeter to introduce patented Liquid Lens technology, which saves time, simplifies set-up, and reduces the possibility of human error in trial lens correction. In perimetry, a trial lens provides the refractive correction needed so each patient can see clearly during the test. The HFA3 replaces the old manual process with a patented Liquid Trial Lens, which automatically delivers the appropriate refractive correction using measurement information entered into the instrument.
