Vector Vision

SKU : CSV-2000

With the CSV-2000, you have the power to test for more than just acuity and contrast sensitivity

  • AcQviz measures the monitor light level and adjusts the level to 85 cd/m2.
  • The CSV-2000 is the only clinical digital vision testing device that automatically calibrates the monitor lighting so that all testing is conducted at the same light level. This standardization ensures consistent vision test results from room-to-room and from practice-to-practice. Auto-calibration is accomplished through patented technology from Guardion Health Sciences (Parent Company of VectorVision), called AcQviz.

Auto-calibration is accomplished through patented technology from Guardion Health Sciences (Parent Company of VectorVision), called AcQviz.
  • This light level is recommended for vision testing by the United States National Academy of Science Working Group on Vision Standards, the United States Food and Drug Administration FDA, and the American National Standards Institute.
  • CSV-2000 test distance can be calibrated from  5 feet to 20 feet.

Legacy Standardized Contrast Sensitivity

  • The CSV-2000 incorporates testing protocol has been the worldwide standard for contrast sensitivity evaluation for more than 20 years, has been used in more than 50 FDA clinical trials and has its accuracy and sensitivity validated in more than 75 research publications or presentations.
  • The use of the standardized CSV-1000 legacy contrast sensitivity protocol allows clinicians to compare their patients’ scores to population norms and to the published data available from the many research studies.

Practice Efficiency

Integration of the contrast sensitivity into a full vision testing suite make the CSV-2000 a breakthrough in refraction efficiency.

  • Contrast Sensitivity test using spatial frequencies : 3 cps, 6 cps, 12 cps and 18 cps
  • Rapid Standardized Testing of Contrast Sensitivity and Glare at any distance
  • Easy to Switch Between All Vision Tests in One Standardized Instrument
  • Accurate results to compare to previous studies and normative values
  • Wall or floor stand mounted. Can be viewed straight on or through the mirror.
  • Published research provides validation for surgical and other treatment outcomes.

Contrast Sensitivity Testing

  • The CSV-2000 has been specifically designed to provide the most sensitive, rapid and accurate test for contrast sensitivity.
  • The test has been proven during the last 20 years to be an excellent documentation tool for cataract vision loss, measure of early vision loss caused eye diseases including AMD, glaucoma and diabetic retinopathy.
  • This test is also an excellent tool for measuring the benefits of treatment, often showing a recovering of vision loss when eye disease is properly treated.

Glare Testing

  • The glare test consists of two symmetric LED light sources that simulate oncoming car headlights.
  • The glare lights initiate at a glare level that simulates oncoming car headlights from a distance of 150 feet.
  • This glare level is precisely calibrated for each device at the factory before delivery to the practice. After the glare lights have been initiated, the testing clinician can adjust the glare light level up and down by using the ‘[‘ and ‘]’ on the key board or the ‘Luminance’ and ‘ATS’ keys on the remote con-trol. Each time the glare lights are turned on, the level of glare is set at the factory to simulate the brightness and appearance of oncoming halogen car headlights at a distance of 150 feet.

Real-World Demonstration for cataract patients and improvement in vision with treatment

  • The real-world scene is very useful for demonstration to cataract patients, and other patients with diminished contrast sensitivity, what it means in the real world to be unable to see low contrast images.
  • The relatives, typically the younger offspring of the cataract patients, are interested to learn why their parents complain about their vision, but have good black and white acuity and can often pass the vision test at the driver’s bureau.
  • The real-world seen is excellent for educating these family members, ie those that have good acuity but are afraid to drive at night or cannot see under low contrast situations.
  • The real-world demonstration is very important to understand why they need cataract surgery or treatment for other eye conditions.
  • The demonstration can also be very useful to show the improvement in vision with treatment, based on a real-world setting.

Mesopic Testing

Mesopic testing is accomplished by the patient taking with test while looking through mesopic filters. These filters are available as a pair of individual trial lenses or with both filters positioned in a wire frame. These options are shown to the right and on the VectorVision website.

Mesopic Testing Instructions

  • Ensure room lighting is set to the proper level; typically all room lights are off and the examination room door closed. Any windows in the examination lane should be blocked. The light level of all reflecting surfaces in the room should be below the light level of the screen as viewed through the mesopic filter.
  • During mesopic testing, the patient must view the test through neutral density filters. These filters can be placed in trial frames, which are worn by the patient, or the filters can be inserted into the phoropter.
