FVA
Functional Vision Analyzer (FVA) (Upgraded Optec 6500)
Ideal for use in pre-and post-op cataract and refractive surgery and clinical trials
- Will perform all of the tests needed to evaluate functional vision and more: visual acuity, contrast sensitivity, depth perception, color vision, and potential acuity.
- Includes F.A.C.T. (contrast sensitivity) tests (sine-wave gratings)
- 4 lighting conditions - Day and night, with and without glare
- 4 lighting conditions - Day and night, with and without glare

INTERPRET THE RESULTS
Abnormal – 1
Are the contrast curves in the gray normal area?
Note: Chart must be at 85 cd/㎡ illumination when using normal curves
Abnormal – 2
If the right and left eye curves are not equivalent
-2 or more patches missed at one frequency level is abnormal
Abnormal – 3
If the right and left eye curves are not equivalent
– One or more patches missed on two adjacent frequencies is abnormal
RECORD FORM
Abnormal – 4
If results fall outside of the normal area it may be a neurological problem:
– Pituitary adenoma
– HIV
– Alzheimer’s disease
RECORD FORM
Abnormal – 5
it results fall outside of the normal area it may be:
Cataracts

I run a busy practice with 9 doctors and 40 assistants in Corpus Christi, TX. I rely upon my
Stereo Optical FVA to provide quick and efficient screening. I own 4 of these units.

I rely on my Functional Vision Analyzer (FVA) in both Research and Clinical Practice, especially for patients with cataracts and/or AMD. The Stereo Optical FVA provides consistent real-life visual simulation of how an individual patient with chronic eye disease actually sees, at distance and near, in terms of contrast and glare, well beyond common 1862 Snellen visual acuity tests.

The Stereo Optical Functional Vision Analyzer® (FVA) is the gold standard clinical and research instrument for evaluating the quality of vision beyond simple visual acuity. The FVA reliably measures the contrast sensitivity function with and without disability glare. This unique instrument therefore provides a full measure of vision assessment, analogous to a full audiogram for hearing function. In addition, the FVA been validated by a number of published clinical papers, and remains the standard in both the eye clinic and pharmacology research laboratory for FDA compliant drug studies. At the Captain James A Lovell Federal Health Care Center, we have used this instrument in several published randomized placebo controlled clinical trials.
