Visual Acuity Testing Systems

Designed to assess the clarity and sharpness of a patient’s visual abilities, visual acuity testing systems are based on having the patient view a chart of optotypes, colors or patterns. A standard part of most exam lanes, visual acuity tests can take a number of forms. At their simplest, these tests can be preprinted cards or charts that can be hung or projected on a wall. However, newer digital visual acuity testing systems are built around computer monitors which allow the system to feature a large number of vision tests that can be accessed via remote control and set up for direct or mirrored viewing. Whether evaluating a new patient or conducting a post-op assessment, a visual acuity testing system can be an important part of a practice.

DescriptionM&S Technologies and Dr. Jack T. Holladay MD, MSEE, FACS, teamed up to produce the Holladay Automated Contrast Sensitivity System, a patented CSF System with rotationally symmetric targets and randomly presented optotypes.

The HACSS provides you

Over 2 years in development, the eLVT system was co-produced and engineered by Dr. Ian Bailey of UC Berkeley and M&S Technologies. It utilizes the Berkeley Rudimentary Low Vision Test and extends the eETDRS protocol to include tumbling E’s, linear Sine Wave Grating Contrast is standard in Smart System 2020. Following the ANSI and ISO specification for contrast testing and calibrated to the FDA guidelines for luminance levels, the Smart System follows a simple screening protocol to allow for

Made in the USA

Smart System 20/20 is the most comprehensive, feature rich and flexible computerized visual acuity testing system available. Optimized with a wide variety of fully randomizable charts, contrast sensitivity and multimedia functions,

The design of the Smart System PC-Plus was developed by pediatric professionals. Features such as hands-free fixation control allow the doctor to perform a retinoscopy while controlling fixation to maintain the child’s attention. Or the new wireless
Features
  • Testing for CSF Under Glare Conditions at low, medium or high luminance levels. Can be performed at either mesopic or photopic luminance levels
  • Preferred Optotypes; Rotationally symmetric targets and randomly presented optotypes. Eliminates biases from the patient with non-rotational symmetric optical aberrations such as residual astigmatism, trefoil, coma, etc.
  • ANSI & ISO Guideline Conformance; Conducts contrast sensitivity testing at (1.5, 3, 6, 12 and 18) cycles per degree and at light levels of 85 cd/m2 (photopic) and 3 cd/m2 (mesopic). Plus, includes all of the options and parameters the agencies require for contrast testing
  • Conduct Standard Vision Testing; Integrate with the M&S Smart System comprehensive visual acuity, contrast sensitivity, fixation and video display systems. Approved for clinical trials using the eETDRS and ATS protocols for visual acuity
  • Quick Test Feature that reduces test time on patient return visits by starting at 0.3 log units above previous threshold, minimizing test time to less than 3 minutes per eye
  • Automated-user interactive testing eliminates technician bias or erroneous data
  • Store multiple test results by patient to track changes in CSF function over time; results can be stored locally or transferred to any media storage device
  • Graph, compare and print patent results against normative data
  • Utilizes Smart System integrated database to store and transmit test results within minutes of test completion via internet connections
  • Track changes in visual acuity levels from visit to visit
  • Proprietary technology to allow testing at 3 meters, 1 meter and 25 centimeters
  • Measures black-white discrimination in patients with acuity below 20/16000
  • Visual acuity thresholds to 20/20000
  • System controlled by any M&S-produced input device
  • Conforms to all ANSI, ISO and FDA guidelines for Visual Acuity testing
  • Provides for consistent and repeatable results
  • Patient results can be printed; can be stored locally or transferred to any media storage device
  • Utilizes Smart System® integrated database to store and transmit test results within minutes of test completion via internet connections
  • Utilize automated protocol that provides results with normative data or manually test patients using the M&S Remote Control or Keypad
  • Measure contrast at ANSI Standard 18, 12, 6, 3 and 1.5 Cycles/Degree from 100% to 0.8% contrast
  • Normative data study conducted in 2010 by Illinois College of Optometry
  • All targets are precisely sized according to the testing distance for maximum accuracy
  • Test in under 5 min
  • Perfect for monitoring progression of cataracts and assessing quality of vision
  • Display a graph comparing your patient’s results to normative data at the end of the testing algorithm
  • Letter Contrast and Linear Contrast Sensitivity Testing with normative data using linear sine wave gratings
  • Glare Testing (optional; shown in photo); use with high or low contrast letters and linear sine gratings
  • Patient Education Interface with Eyemaginations and EyeMotion
  • DVD Play; play any DVD on the Smart System for education and fixation
