(a) Densitometric evaluation of Scheimpflug images to measure backward light-scattering from the lens and (b–d) psychophysical measurements of forward intraocular light-scattering. Light-scattering is shown as a function of (a,b) age, (c) the cataract score and (d) cataract type. (a) C1, C3 and N (nucleus) are lens zones according to figure 1b. (d) N, nuclear; C, cortical; PS, posterior subcapsular; N–C, mixed nuclear and cortical; N–C–PS, mixed nuclear, cortical and posterior subcapsular. Error bars show the confidence interval for the mean. Figure 2a reprinted from Sasaki [41], with permission from Deutsche Akademie der Naturforscher Leopoldina—Nationale Akademie der Wissenschaften.
