Humphrey Field Analyzer 3 (HFA3) 840 — Refurbished Visual Field Analyzer with GPA

The 840 vs 860 distinction: the 860 adds the 60-4 peripheral pattern, the Esterman binocular driver-license pattern, and the motorized electric table base. The 840 is the focused-glaucoma version — same SITA testing engine, GPA progression analysis, and clinical reporting at a lower refurbished price point. For optometry practices doing standard glaucoma visual-field testing without DOT/aviation Esterman work, the 840 covers the full clinical workflow.
According to a National Library of Medicine-indexed study (Indian J Ophthalmol, 2026), ophthalmic-instrument repeatability depends heavily on operator-instrument interaction — supporting the standardized SITA testing protocols Humphrey has refined across multiple generations.
Why Practices Choose the HFA3 840
- Full SITA suite — SITA Standard, Fast, Faster, and SWAP.
- 24-2, 30-2, 10-2 patterns — covers all standard glaucoma and macular field protocols.
- Glaucoma Progression Analysis (GPA) — Zeiss gold-standard event + trend reporting.
- Modern HFA3 platform — current-generation hardware vs older HFA II/II-i units.
- Touchscreen patient-side controls — streamlined operator workflow.
- USB report export — EMR-friendly workflow.
- Refurbished tier with 6-month DEC warranty — substantial savings vs new ($25K+ new MSRP).
- Zeiss US service network — extensive parts and consumable availability.
Clinical Applications
- Glaucoma diagnosis and monitoring — standard SITA 24-2/30-2 with GPA progression analysis.
- Macular pattern testing — 10-2 for macular and post-vitrectomy field assessment.
- Stroke / neurological field defects — 30-2 hemianopia and quadrantanopia documentation.
- Early-glaucoma SWAP testing — short-wavelength automated perimetry.
- Optic nerve disease follow-up — ischemic optic neuropathy, optic neuritis monitoring.
- Pre/post medication monitoring — hydroxychloroquine, vigabatrin field monitoring.
Who This Is For
- Optometry and ophthalmology practices doing routine glaucoma visual-field testing.
- Glaucoma specialists wanting Zeiss GPA progression reporting.
- Multi-doctor groups standardizing on HFA3 for consistent SITA data across visits.
- Practices replacing aging HFA II or II-i units.
- Buyers comparing HFA3 840 vs 860 (840 = no Esterman, no electric table, lower price).
