Refurbished. This Humphrey Matrix 715 has been inspected and verified for full FDT visual field testing function — including stimulus presentation, threshold testing, and eye monitoring — prior to sale. Covered by a 6-month warranty on parts and workmanship.
Visual Field Analyzer Humphrey Matrix 715 FDT — Refurbished Perimeter
The Humphrey Matrix 715 is a dedicated visual field analyzer using Frequency Doubling Technology (FDT) to detect glaucomatous visual field loss with high sensitivity, including pre-perimetric and early-stage defects that standard white-on-white perimetry may miss. With a 30° field of view, 69 test stimuli, and a 35-second supra-threshold screening mode, the Matrix 715 is engineered for efficient glaucoma screening in busy clinical settings. Full threshold strategies cover 24-2, 30-2, N-30, 10-2, and Macula FDT patterns, while video eye monitoring simplifies patient alignment and reduces fixation-loss errors that compromise visual field reliability. The compact tabletop footprint installs in standard exam lanes without the dedicated room space required by full bowl perimeters. This refurbished Matrix 715 is sold inspected and backed by Digital Eye Center’s 6-month warranty.
According to the National Library of Medicine, Frequency Doubling Technology demonstrates strong diagnostic accuracy for glaucoma detection — confirming FDT-based visual field analyzers as clinically validated tools for glaucoma screening and monitoring alongside standard automated perimetry.
Why Practices Choose the Humphrey Matrix 715 Visual Field Analyzer
The Matrix 715 delivers glaucoma-specific visual field testing in a faster, more compact format than full bowl perimeters — making it the preferred choice for practices adding perimetry or running high-volume glaucoma screening programs.
- Frequency Doubling Technology (FDT) — targets the magnocellular visual pathway preferentially affected in early glaucoma, enabling detection of field defects before they become visible on standard SAP testing, supporting earlier intervention and treatment decisions.
- 35-second supra-threshold screening — the N-30 screening protocol covers the central 30° in 35 seconds per eye, enabling efficient glaucoma screening in time-limited appointments, health fairs, and high-throughput clinical settings.
- 69 test stimuli across 30° FOV — full threshold strategies use 69 stimuli distributed across the 24-2, 30-2, N-30, 10-2, and Macula FDT patterns, providing comprehensive central and paracentral visual field coverage for glaucoma characterization.
- Video eye monitoring — built-in camera continuously tracks pupil position and fixation during testing, automatically flagging fixation losses and gaze deviations that reduce test reliability without requiring manual patching or fixation loss wells.
- Full threshold and supra-threshold strategies — the Matrix 715 supports both rapid screening (35-second N-30) and comprehensive threshold testing (24-2 and 30-2 FDT Full Threshold), enabling the same instrument to serve both screening and diagnostic follow-up roles.
- Compact tabletop footprint — unlike bowl-style automated perimeters requiring dedicated exam rooms, the Matrix 715 mounts on a standard exam table and can be stored when not in use, supporting multi-purpose exam lanes in smaller practices.
- Established clinical validation — the Matrix FDT platform has been studied extensively in peer-reviewed literature for glaucoma detection sensitivity and specificity, providing a documented evidence base for clinical decision support.
Clinical Applications
- Glaucoma suspect screening — FDT supra-threshold testing identifies functional field defects in ocular hypertension, suspicious disc appearance, and elevated IOP patients who require perimetric baseline before starting treatment.
- Early glaucoma detection — FDT’s sensitivity to magnocellular pathway damage enables field defect detection at earlier stages than standard achromatic perimetry, supporting pre-perimetric glaucoma diagnosis and earlier treatment initiation.
- Glaucoma monitoring and progression — serial full threshold FDT testing (24-2 and 30-2) tracks visual field change over time, supporting mean deviation trend analysis and rate-of-progression calculations for glaucoma management decisions.
- Neuro-ophthalmology screening — FDT field maps detect hemianopic and quadrantanopic defects from optic nerve, chiasmal, and cortical lesions, supporting neurological referral triage in practices evaluating unexplained visual symptoms.
- Occupational and population screening — the 35-second per-eye screening time makes the Matrix 715 practical for occupational vision screening programs, diabetic eye care clinics, and community glaucoma screening events.
- Post-surgical field monitoring — objective perimetric follow-up after glaucoma filtration surgery, tube shunt, or MIGS procedures tracks post-operative field stability and recovery over successive visits.
Who This Is For
- Ophthalmology and glaucoma specialty practices adding FDT perimetry as a fast, validated complement to their existing SAP perimeter, or as a primary screening tool for high-volume glaucoma suspect workups.
- Optometry practices managing glaucoma suspects and ocular hypertension patients who need a perimeter for threshold field testing without the cost and space requirements of a full bowl automated perimeter.
- Multi-specialty and comprehensive eye care clinics that benefit from the Matrix 715’s dual role as a rapid screener and diagnostic threshold perimeter within a single compact device.
- Budget-conscious practices seeking a fully functional refurbished glaucoma perimeter at a significantly lower cost than new full bowl perimeters while maintaining clinical validation and Zeiss/Humphrey brand quality.
