DUBLIN, Calif., March 18, 2015 — Carl Zeiss Meditec Inc. has introduced a new version of its Humphrey Field Analyzer, the HFA3, for glaucoma diagnostics. 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 the patented Liquid Trial Lens, which automatically delivers the appropriate refractive correction using measurement information entered into the instrument. Additionally, the RelEYE feature allows doctors to instantly review the patient’s eye position at any stimulus point to reveal common testing problems such as droopy lids (ptosis) or misalignment of the eye relative to the trial lens holder. Faster gaze tracking provides information that helps doctors assess the reliability of test results.
