ZEISS HFA3 Humphrey Field Analyzer
Humphrey Field Analyzer 3 from ZEISS
Reduce testing time and increase insight into glaucoma.
Product Information
The ZEISS Humphrey Field Analyzer 3 (HFA3) is an innovative device designed to advance clinical efficiency in the diagnosis and management of glaucoma. It is a reliable tool that thousands of practices depend on for essential diagnoses.
The HFA3 features SITA Faster Testing, which optimizes test results for both the healthcare professional and the patient. SITA adapts to patient responses, making optimal use of the information contained in the patient’s responses and continuously refining the measurements. This ensures accurate and insightful analysis of the patient’s visual field.
The HFA3 offers various testing strategies, including SITA Faster 24-2C, SITA Fast 24-2, and SITA Standard 24-2. The new SITA Faster 24-2C test adds 10 test points to the 24-2 pattern, specifically examining areas along physiologically relevant nerve fiber bundles known to be susceptible to glaucomatous defects.
The HFA3 also includes STATPACTM statistical software, which compares test results to proprietary age normative and glaucoma databases. This allows for expert analysis of changes in the patient’s visual field over time.
Product Usage Instructions
- Position the patient comfortably in front of the Humphrey Field Analyzer 3.
- Select the appropriate testing strategy based on the patient’s condition and requirements. Options include SITA Faster 24-2C, SITA Fast 24-2, and SITA Standard 24-2.
- Explain the test procedure to the patient, ensuring they understand the importance of accurate and reliable responses.
- Initiate the test and allow the patient to respond to the presented stimuli.
- During threshold testing, the HFA3 will adapt to the patient’s responses, continuously refining measurements for optimal accuracy.
- Monitor the test progress and ensure the patient maintains focus and attention throughout the duration of the test.
- Once the test is complete, the HFA3 will generate visual field test results.
- Utilize the STATPACTM statistical software to analyze changes in the patient’s visual field over time, comparing results to age normative and glaucoma databases.
- Based on the analysis, provide expert insights and recommendations for the patient’s diagnosis and management of glaucoma.
Reduce testing time and increase insight into glaucoma.
ZEISS Humphrey Field Analyzer 3

- Streamline workflow. Reduce set-up time and provide best test results with the Liquid Trial Lens™ and automated eye alignment.
- Interact with results. Access HFA3 results and the entire patient test history as well as change baselines on the fly.
- Synchronize data for complete patient history. Test patients at any HFA3 or HFAII-i, and generate reports with complete test history.
- See the whole picture. HFA is the cornerstone of the Integrated Diagnostic Imaging platform for glaucoma
that provides a new level of information for optimal patient management based on visual field function and corresponding OCT structure data.
Everything you depend on, only from a Humphrey
The innovations in HFA3 add to the reliable standard that thousands of practices already depend on for essential diagnoses.
SITA “adapts” to patient responses
HFA SITA™ Strategies are the standard of care in visual field testing. SITA
makes optimal use of the information contained in the patient’s responses,
looks at the complete pattern of patient responses while thresholding, and
continuously refines the measurements.
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 central visual field
The new SITA Faster 24-2C test adds 10 test points to the 24-2 pattern. They were selected to examine areas along physiologically relevant nerve fiber bundles known to be susceptible to glaucomatous defects.1-6
Expert analysis of visual field test results
STATPAC™ statistical software compares results to proprietary age normative and glaucoma databases for analyzing changes in the patient’s visual field over time.

Inform your decision-making with GPA
GPA™ (Guided Progression Analysis) is designed to help you identify where, and how fast, defects are progressing. GPA allows transition to new SITA tests while maintaining analysis of the complete patient history.
Identify consecutive change at each test point
Progression Analysis Probability Plot is designed to identify statistically significant progression events in consecutive visits at individual test points. GPA Alert displays a plain language message about the likelihood of disease progression.
Visualize rate of progression
Visual Field Index™ (VFI) is a measure of the patient’s overall visual function as compared to an age-adjusted normal population. VFI trend analysis helps differentiate rapid versus slow progressing visual field loss.
HFA3 makes visual field testing faster and easier than ever
Simple to operate
- Liquid Trial Lens technology reduces setup time by automatically loading each patient’s refractive correction from the previous exam.
- Automated eye alignment centers the patient’s eye to the trial lens and adjusts to the patient during the test to provide fast setup and best results.
- With the intuitive SmartTouch interface you simply select the patient’s name and press start to begin testing.
Enhancing workflow from patient testing to report review
New Review Software delivers comprehensive analysis and improves digital workflow.
- Quickly access HFA reports in every exam lane.
- Modify reports on-the-fly to include and exclude tests, reset baselines and follow up on tests.
- Simple visual reports foster clear patient communication, which may help improve compliance.
Data Synchronization automatically updates and integrates patient tests from any connected HFA3. HFA-IIi contributes tests to HFA3, enabling you to use existing HFA-IIi devices to supplement testing capacity.

Integrated Diagnostics Imaging platform for Glaucoma
Glaucoma management is evolving to require a new diagnostic environment to
support your clinical assessment when and where you need it.
The Integrated Diagnostics Imaging platform delivers information critical to
understanding and managing your patients by offering connection to multi-
modality data sets. The combined analysis of HFA3 and CIRRUS™ HD-OCT lets you
observe, identify and evaluate structural and functional changes earlier, for
better glaucoma management.
