The Worldwide Leader in Standardized Vision Testing

CSV-1000

The CSV-1000 instrument is the recognized Worldwide Leader for standardized contrast sensitivity, ETDRS and glare testing

CSV-1000

Why the CSV-1000

The patented auto-calibration circuitry provides for standard and consistent test conditions without a hassle. The instrument automatically controls the test lighting to a level of 85 cd/m2, which is the light level recommended for vision testing by the National Academy of Sciences and adopted by the FDA as the required testing light level for clinical trials. Ease of use is one reason why the CSV-1000 is used in eye clinics in more than 60 countries. All you have to do is turn on the device and it is ready to evaluate patients using standardized and highly accurate tests. The CSV-1000 comes in two forms, the CSV-1000 without glare and the CSV-1000HGT with glare (HGT means Halogen Glare Test). The device is offered with a variety of test faces. These test faces are placed on the front of the CSV-1000 to evaluate contrast sensitivity, ETDRS, low contrast acuity, etc. They are held in position by a magnet and can be easily interchanged. The sister product, the CSV-2000, offers the same range of tests, plus more, via computerized software. No test faces are used with the CSV-2000, the tests are changed via remote control. The different types of test faces available for the CSV-1000 are shown on other pages of this website.

Instrument of Choice

In addition to its use as a clinical tool in more than 5,000 eye care practices world-wide, the CSV-1000 is routinely used for research and to evaluate visual performance. It has been selected for use in numerous multi-center trials in the United States and around the world for the standardized measurement of contrast sensitivity, ETDRS acuity, low contrast acuity and glare sensitivity. These studies include those for the evaluation of LASIK surgery, IOLs, contact lenses, presbyopia correction, athlete visual performance, glaucoma detection and treatment, visual impact of pharmaceutical treatments, nutritional supplements, etc. Companies who have sponsored these trials include Alcon, Abbot Medial Optics, Bausch and Lomb, Merck, Sharp & Dohme, Pharmacia, LensTec, Staar Surgical and Johnson & Johnson to name a few. It has been used by the Olympic Vision Centres to screen athletes for numerous Olympic Games since 1992 and for the evaluation of multiple professional and collegiate sports teams.
