Figure 1.
Schematic representation of a) the macroscope setup with a dark field ring illuminator; and b) the setup to quantitatively measure scattered light under different angles.
Figure 2.
Dark field images of the IOLs acquired with the macroscope setup.
Dark regions represent low scattering and light areas represent high scattering. In both images the laser pits and cracks are demarcated. a) IOL with 15 damaged areas with a circumference of approximately 3.5 mm; and b) IOL also with 15 damaged areas, but a circumference of 2–2.5 mm.
Figure 3.
Microscope magnifications of several laser induced damaged areas in the IOLs from figure 2.
a) area 3 in figure 2a; b) area 5 in figure 2a; c) area 1 in figure 2b; d) area 4 in figure 2b. Laser-induced damage was scored as mild damage except for c) which was scored as moderate damage.
Figure 4.
PSF of 6 individual pits (bottom 6 curves in each figure) for the IOL of a) figure 2a and b) figure 2b.
The line with closed circle symbols represents the estimated total contribution of all pits in the IOL. The top PSF illustrates the PSF-model, according to the CIE, of a 35–year-old individual.
