Condition & Warranty
Used. This Zeiss Humphrey Matrix 800 Visual Field Analyzer package has been fully inspected, optical-bench calibrated, and clinically tested. The internal projection system displays sharp, high-contrast flicker-stimuli targets, and the built-in LCD operator screen is bright and responsive. The motorized chinrest mechanism adjusts smoothly across its vertical range, and the patient response button registers instantly without stickiness or input lag. The chassis shows minor superficial cosmetic handling as expected for a pre-owned diagnostic instrument. Covered by a 90-day warranty on parts and workmanship.
Zeiss Humphrey Matrix 800 — Used Workstation for Early Glaucoma Detection
The Zeiss Humphrey Matrix 800 is an advanced, highly efficient visual field perimeter engineered specifically for rapid glaucoma screening and functional loss detection. Utilizing patented Frequency Doubling Technology (FDT), the Matrix 800 isolates and tests the magnocellular ($M_y$) ganglion cell pathway. Because $M_y$ cells have low redundancy and are among the earliest damaged by elevated intraocular pressure, the Matrix 800 detects visual field loss years earlier than conventional white-on-white perimetry.
Designed for maximum clinic efficiency and patient comfort, the Matrix 800 operates without requiring darkroom conditions or trial lenses for patients within $\pm 3$ diopters. With rapid screening protocols capable of evaluating an eye in as little as 90 seconds, alongside full threshold diagnostic tests (such as 24-2, 30-2, and N-30), this used workstation allows practices to double their visual field screening throughput while maintaining full diagnostic compatibility with standard Humphrey Field Analyzer (HFA) statistical software models.
Research published in the National Library of Medicine confirms that Frequency Doubling Technology (FDT) perimetry implemented on the Zeiss Humphrey Matrix exhibits exceptional sensitivity in identifying early pre-perimetric glaucomatous damage prior to detectable changes on standard SAP white-on-white visual field tests.
Why Practices Choose the Zeiss Humphrey Matrix 800
-
Frequency Doubling Technology (FDT) — Selectively targets magnocellular pathway cells to catch functional glaucoma damage at its earliest stages
-
90-Second Rapid Screening Protocols — Delivers high-speed supra-threshold visual field tests to quickly identify abnormalities in high-volume patient flows
-
No Trial Lenses Required — Advanced optical engine accommodates refractive errors within $\pm 3$ diopters without needing messy trial lens frames or lens insertion
-
Ambient Light Operation — Perform full visual field testing in normal room lighting, eliminating the need for a dedicated darkroom lane
-
Integrated Motorized Chinrest — Operator-controlled vertical adjustment ensures fast, ergonomic patient positioning and structural stability during long threshold runs
-
Humphrey (HFA) Software Consistency — Utilizes familiar Statpac analytical software displays and normative databases, allowing seamless comparison with legacy HFA perimeter results
-
Compact All-in-One Design — Lightweight tabletop footprint with integrated processing screen and thermal printer fits easily into any pre-testing room or secondary lane
Clinical Applications
-
Early Glaucoma Detection & Screening identifying pre-perimetric optic nerve damage and ganglion cell loss before visual field defects appear on standard white-on-white perimetry
-
High-Speed Pre-Testing Workflows screening routine eye care patients in 90 seconds per eye to determine if full threshold perimetry is warranted
-
Longitudinal Glaucoma Management tracking visual field progression over time using standardized 24-2, 30-2, and 10-2 threshold testing patterns
-
Neurological Visual Field Evaluations detecting hemianopic and quadrantanopic visual field defects stemming from cerebrovascular accidents (strokes) or pituitary lesions
Who This Is For
-
Optometrists and General Ophthalmologists seeking a fast, highly sensitive screening perimeter to catch early glaucoma without slowing down clinic flow
-
High-Volume Practices & Satellite Clinics looking for a compact, ambient-light perimeter that doesn’t occupy a dedicated dark room
-
Comprehensive Eye Care Centers wanting an affordable secondary perimeter to handle pre-testing overflow and routine screening protocols
