Summary of Independent Evaluation of Konan Medical CCT HD
"The CCT HD, with very precise color calibration, can achieve the very low cone contrast values needed to accurately quantify cone contrast thresholds even for CVN (Color Vision Normal) individuals. The capability to test CVN individuals is essential in order to research the relationship between color vision and operationally relevant performance.
Additionally, the CCT HD, with precise calibration and excellent test-retest reliability can also enable early detection of disease, improved ability to quantify the effect of hypoxia and other environmental stressors on vision, and improved ability to investigate the potential effects of chemicals/pharmaceuticals.
The precise calibration also enables binocular testing, which is not possible with the RCCT (Rabin CCT) due to the ceiling effect. The RCCT was a substantial improvement over PIP tests (e.g., Ishihara) when it was introduced, and the CCT HD is a substantial improvement over other commercially available CCTs. "
