Relationship between wave aberrations and histological features in ex-vivo porcine crystalline lenses

Wave aberrations of isolated ex vivo porcine crystallinelenses were measured by using a point-diffraction interferometer. Thismethod allowed us to gain greater insight into the detailed aberrationstructure of eye lenses showing systematic presence of some dominantaberrations. In order of significance, astigmatism together withspherical aberration, coma, and trefoil are the main aberrationspresent in all lenses. We found a high correlation between the axis ofboth astigmatism and trefoil with the Y-shaped suture planes of thelens, revealing a subtle relationship between the induced aberrationsand the histological features.
