The aim of our investigation was to examine the possible correlations between optical aberrations, angle kappa, angle alpha and the visual outcomes following cataract surgery. 56 eyes of 28 patients were implanted with the Liberty 677MY trifocal intraocular lens (IOL). Pre- and postoperative higher order aberrations, coma, astigmatism, angle alpha and angle kappa were registered, along with uncorrected and corrected visual acuities at multiple distances. Visual acuity and contrast sensitivity defocus curves were plotted and the areas under curve were calculated 1 and 3 months postoperatively.
