Functional Vision Analyzer (FVA) – Upgraded Optec® 6500

Comprehensive assessment of functional vision

The Functional Vision Analyzer (FVA) from Stereo Optical is designed to evaluate how patients perform visually under different lighting and glare conditions. Upgraded from the Optec® 6500, the system is ideal for preoperative and postoperative cataract and refractive-surgery evaluations, clinical research and functional-vision assessment.

The FVA performs the tests required to evaluate visual acuity, contrast sensitivity, depth perception, color vision and potential acuity. Its integrated F.A.C.T.® contrast-sensitivity test uses sine-wave gratings at five spatial frequencies: 1.5, 3, 6, 12 and 18 cycles per degree.

Four testing conditions reproduce daytime and nighttime environments, both with and without glare. Microprocessor-controlled illumination is continuously calibrated to provide homogeneous lighting and consistent testing conditions.

The system meets FDA clinical-research requirements and applicable ANSI standards. Its background luminance complies with international standards, while binocular glare testing helps assess performance in visually demanding environments.

EyeView software complements the clinical assessment by using real-world images to demonstrate the practical effects of reduced contrast sensitivity and other changes in functional vision.
