Visualization of Light Propagation with Multifocal Intraocular Lenses Using the Ouzo Effect

Figure 9

A comparison of a multifocal IOL immersed in two different visualization media: ouzo in water (a) vs. fluorescein in water (b) both illuminated with a green laser (λ=532 nm). The medium containing ouzo (a) shows more Schlieren in the image, while the medium containing fluorescein (b) seems to provide a sharper image. Scattering from particles in the medium is visible in both images (adopted from [28]).
