Ocular straylight has been measured by means of psychophysical methods over the years. This approach gives a functional parameter yielding a straight comparison with optically defined light scattering, and the Point Spread Function. This is of particular importance when the effect of intraocular lenses (IOLs) on postoperative straylight is sought. An optical system for straylight measurements of IOLs was adapted to a commercial device (C-Quant, Oculus), which employs such psychophysical method. A measurement principle of the proposed by the CiViUM group methodology along with the results of different IOL models have been recently published in the Journal of Biomedical Optics Express (G. Łabuz, F. Vargas-Martín, T.J.T.P. van den Berg, N. López-Gil, “Method for in vitro assessment of straylight from intraocular lenses,” Biomed. Opt. Express 6, 4457-4464)
