Humphrey Matrix 800 — Used Frequency-Doubling Visual Field Analyzer
The Humphrey Matrix 800 is the upgraded Matrix-platform frequency-doubling perimeter from Zeiss — providing early-glaucoma detection sensitivity via frequency-doubling technology (FDT) stimulus presentation in 24-2 and 30-2 patterns. This used humphrey matrix 800 ships ready for early-glaucoma screening workflows at sub-$7K Used pricing.
The Matrix platform’s defining feature is FDT — a stimulus type that selectively probes the magnocellular pathway, providing earlier detection of glaucomatous field loss than standard achromatic perimetry in some patients. The Matrix 800 is an upgrade over the FDT 710 with broader test pattern support and modern reporting.
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 FDT acquisition workflow Humphrey Matrix delivers.
