Humphrey 740i Floppy — Refurbished Visual Field Analyzer with Printer
The Humphrey 740i floppy is the entry-level instrument in the HFA II-i visual field analyzer series — delivering full SITA Standard and SITA Fast automated perimetry for glaucoma diagnosis and monitoring. This refurbished Humphrey 740i floppy pairs the gold-standard SITA perimetry engine with an integrated printer and the original floppy disk data transfer system, making it a complete standalone perimetry station for practices that need reliable visual field testing without USB or network connectivity. For clinics where the perimeter functions as a dedicated workstation and paper-based or floppy-archived reports meet documentation requirements, the Humphrey 740i floppy delivers HFA II-i quality at the most accessible price point in the Humphrey lineup. A comprehensive review published in Survey of Ophthalmology identifies SITA Standard and SITA Fast as the established algorithms for visual field testing in glaucoma, confirming that SITA-based threshold perimetry on instruments like the Humphrey 740i floppy meets the clinical standard for glaucoma diagnosis and monitoring across all practice settings.
Why Practices Choose the Humphrey 740i Floppy
- SITA Standard and SITA Fast perimetry — the same clinically validated SITA algorithms as higher-tier HFA II-i instruments; 24-2, 30-2, and full SITA test patterns for the glaucoma monitoring encounters that dominate most VF testing schedules.
- Integrated printer included — on-site visual field report printing with single-field analysis and overview outputs; no networked printer or external device required for daily operation.
- Standalone floppy configuration — original factory storage system appropriate for dedicated perimetry workstations; floppy-based test data is exportable to external storage for archiving; SITA perimetry performance is unaffected by data transfer medium.
- GHT and Pattern Deviation analysis — Glaucoma Hemifield Test and age-matched Pattern Deviation probability plots on every report; the statistical outputs that glaucoma staging and progression monitoring require.
- Most accessible HFA II-i price point — refurbished Humphrey 740i floppy at $7,125 is the lowest-priced Humphrey II-i instrument available; 6-month warranty covers the unit and integrated printer.
- HFA platform familiarity — clinicians already trained on HFA perimetry operate the 740i floppy without retraining; reports follow the standard Humphrey format recognized by glaucoma specialists and referring physicians.
Clinical Applications
- Glaucoma visual field diagnosis and staging — SITA 24-2 and 30-2 testing for initial diagnosis, staging, and documentation of visual field loss in open-angle and other glaucoma types.
- Serial glaucoma monitoring — GHT and Pattern Deviation analysis support longitudinal visual field tracking in established glaucoma patients on stable or escalating therapy.
- Ocular hypertension baseline perimetry — baseline and conversion monitoring in patients with elevated IOP and normal visual fields.
- Standalone perimetry in low-connectivity settings — suitable for offices, satellite clinics, or mobile screening programs where network or USB connectivity is unavailable or unnecessary.
- Neurological visual field assessment — full-threshold and SITA testing for detection and monitoring of visual field defects in neuro-ophthalmic conditions.
Who This Is For
- General ophthalmology practices needing an affordable dedicated perimetry workstation with integrated printing and no network dependency.
- Glaucoma-focused practices looking to add a second perimeter for high-volume scheduling without the cost of a top-tier HFA unit.
- Satellite and rural clinics where standalone operation is preferred and paper-based visual field documentation meets workflow requirements.
- Practices transitioning from older perimeters seeking a refurbished HFA II-i at a lower entry cost than USB-equipped models.
