Product Description
HUMPHREY FDT 710 VISUAL FIELD INSTRUMENT
FREQUENCY DOUBLING TECHNOLOGY
The FDT Visual Field Instrument is an innovative, efficient, compact and affordable automated visual field testing instrument. Years of research and clinical trials of welch Allyn's patented FREQUENCY DOUBLING TECHNOLOGY have resulted in an instrument which provides rapid, clinically validated and user-friendly visual field testing.
Key features of the FDt Visual Field Instrument include:
- Supra-threshold screening test in less than 1 minute per eye
- full-threshold test in approximately 4 minutes per eye
- Easy to use; no special training is needed/minimal operators instruction
- No corrective (trial) lens needed; patients can wear their own correction or none at all (must only be withing 7D of patient's refraction)
- No eye patch needed for the opposite (untested) eye - it's automatically occluded
- Not affected by ambient lighting - can be used in normal room lighting
- Not affected by pupil size (as small as 2 mm)
- Extensive age-normative reference database incorporated
- World-class clinical validation by leading researchers in the field
- Statistically significant correlation to the Humphrey Field Analyzer
- Software upgrade capability for future enhancements
