VectorVision Contrast Sensitivity for Clinical Trials

Since 1991, VectorVision contrast sensitivity tests have been a mainstay for clinical trials that measure contrast sensitivity, ETDRS acuity, low contrast acuity and glare sensitivity. The self-standardized systems automatically initiate and maintain a light level of 85 cd/m² for testing. This light level is recommended by the FDA for vision evaluation. The system is also easy to use and requires no maintenance, thus greatly reducing overhead in clinical trials.

Glare Testing

The CSV-2000 and CSV-1000HGT provide a glare option for clinical trials. This test incorporates a standardized glare source into the device so that a wide variety of vision tests can be used under glare conditions. The FDA and other agencies now require standardized glare testing for evaluation of new refractive surgery and IOL technology.

Mesopic Testing

The FDA requires mesopic light levels for testing in many clinical trials. The CSV-2000 and CSV-1000 can be used with specially designed mesopic (neutral density) filters to reduce the testing light level to the recommended testing level of 3 cd/m². Also, the Clinical Trial Suite (CTS) version of the CSV-2000 offers a second set of contrast sensitivity gratings that provide higher contrast levels for testing patients in mesopic conditions, if needed

Instrument of Choice

The VectorVision devices have been selected for use in numerous multi-center trials in the United States and around the world for the standardized measurement of visual capability. These studies include those for the evaluation of LASIK surgery, IOLs, contact lenses, presbyopia correction, athlete visual performance, visual impact of pharmaceutical treatments, nutritional supplements, and many others. Companies who have sponsored these trials include Alcon, Abbot Medial Optics, Bausch and Lomb, Merck, Sharp & Dohme, Pharmacia, LensTec and Johnson & Johnson to name a few.
