C-Quant

The Oculus C-Quant is a specialized ophthalmic device used to measure intraocular straylight, which is the scattering of light within the eye. This measurement helps quantify a patient's visual complaints, such as glare sensitivity, halos, or night blindness, that may not be detected by standard vision tests. It uses a psychophysical "compensation comparison" method to determine a straylight value, providing an objective assessment of a patient's visual quality. The device is particularly useful for evaluating the effects of cataracts, corneal opacities, and post-refractive surgery issues. The results can help guide clinical decisions and monitor a patient's visual health over time.
