ZEISS Humphrey Field Analyzer 3

Advancing clinical efficiency in glaucoma

As the gold standard of perimetry, Humphrey® Field Analyzer 3 (HFA3) is your trusted diagnostic partner. HFA3 delivers the interactive analysis you need, when and where you need it.

  • Reduce visual field testing time with SITA™ Faster.
  • Central testing to view into the macula with SITA Faster 24-2C
  • Mixed Guided Progression Analysis™ (GPA™): intermixing of SITA Standard, SITA Fast and SITA Faster.
  • Simplify setup time with a single trial lens. Using liquid pressure, the new Liquid Trial Lens™ instantly delivers each patient's refractive correction with the touch of a button.*
  • Simplify operation with the intuitive new SmartTouch™ interface.
  • Gain peace of mind with seamless transferability of legacy data from the HFA II and HFA II-i to the HFA3.

Minimize time. Maximize information.

NEW SITA Faster testing strategy

  • Reduce testing time by up to 50% with SITA Faster 24-2 threshold testing.
  • The NEW SITA Faster 24-2C test adds ten additional points for central visual field. 
  • The points selected cover the areas that are known to be susceptible to glaucomatous defects.

Threshold testing is faster than ever with SITA Faster 24-2

SITA Faster 24-2 improves clinical workflow and patient satisfaction with the fastest test time in HFA threshold testing. Approximately 50% faster than SITA Standard, SITA Faster 24-2 is also about 30% quicker than SITA Fast, yet offers the same reproducibility.

Obtain more information in the central visual field

New SITA Faster 24-2C adds ten test points to the 24-2 pattern, which were selected to examine areas along physiologically relevant nerve fiber bundles known to be susceptible to glaucomatous defects.

What do the experts think?

Doctors speak on Glaucoma Management, SITA Faster & the new 24-2C Testing Pattern

Dr. Murray Fingeret, SUNY College of Optometry, New York

The idea of the 24-2C is that it takes all the points on the 24-2 and it adds ten points from the 10-2. So now you have 64 points—but the idea is those ten points right in that center 10-degrees are the ones thought to be the ones most commonly flagged if glaucoma develops.

Dr. Richard Madonna, SUNY College of Optometry, New York

(The new HFA3 tests) are going to be incredibly important to us as we look at, #1, getting better visual field tests because they’re faster, and/or #2, gathering information about the central 10 degrees in the visual field.

Informing your decision-making with GPA

Guided Progression Analysis (GPA™), an HFA software module, can add value to your practice.

GPA Adds Value to Your Practice

Guided Progression Analysis (GPA) provides an overview of the patient’s entire visual field history, streamlines workflow and can improve clinical confidence. GPA simplifies and standardizes analysis of changes in glaucomatous visual fields.

  • Highlights any changes from baseline that represent larger than expected clinical variability
  • Provides plain-language messages whenever changes show consistent and statistically significant loss

It helps to differentiate between the localized losses typical of glaucoma and overall depressions caused, for example, by progressive cataract.

  1. Visual Field Index™ (VFI™) Trend is a regression analysis of the VFI values. It plots visual field loss against the patient's age, as well as rate of progression.
  2. Glaucoma Change Probability Map is designed to identify progression events in consecutive visits at individual test points.
  3. GPA Alert displays a plain language message about the likelihood of disease progression.
Guided progression analysis adds value to your practice.

Enhancing workflow from patient testing to report review

New HFA Review software provides comprehensive analysis and improves digital workflow. Quickly access HFA reports in every exam lane and modify reports on-the-fly to include and exclude tests, reset baselines and follow up on tests.
