Abstract

To investigate the impact of intraocular lens (IOL) decentration $\le \pm 1\mathrm{\hspace{0.17em}}\mathrm{\hspace{0.17em}}\mathrm{mm}$ and IOL tilt $\le \pm 10°$ on the fixation axis and spherical equivalent refraction (SE), 50 pseudo-phakic eyes were simulated using numerical ray-tracing. We computed the position of the object point whose image ends up at the virtual fovea for each scenario and estimated the corresponding change of fixation axis and SE. The eye turned opposite to the direction of IOL decentration or tilt to compensate for the associated prismatic effect (angle $<1.2°$). Decentration of the aspheric IOL resulted in a hyperopic shift ($<0.57$ D), and tilt in a myopic shift ($<0.77$ D).
