Fig. 6

(a) Representative modulation transfer function (MTF) of an opacified IOL (IOL 6) showing a deterioration at all spatial frequencies. The green line represents the diffraction limit. Blue lines represent the measured MTF values in sagittal (solid blue line) and tangential (dashed blue line) planes. (b) Representative MTF of a clear monofocal aspheric IOL from hydrophilic acrylate (CT Asphina 409 MP, Carl Zeiss Meditec, Jena, Germany) taken in our laboratory for comparison. (c) USAF target image obtained through IOL 6 at standard lighting conditions showing a significant reduction in light transduction. (d) With light adjustment an acceptable image quality could be achieved
