Aspherical intraocular lenses are developed to reduce or fully eliminated spherical aberrations of the pseudophakic eye after cataract surgery with implantation of a posterior chamber lens in order to optimize the optical performance of the eye. Currently there are 2 different concepts of aspherical lenses on the market: aberration free intraocular lenses which do not add spherical aberration to the optical system eye (but do not correct spherical aberration of the cornea) and fully correcting aspherical intraocular lenses, which are developed to correct the spherical aberration of an average human eye (e.g. model eye).
In this talk we would like to give an overview on these concepts for aspherical lenses. We would like to discuss the validity of parameters of an average human eye as a reference for the general population and address the impact of misalignment (in terms of decentration, tilt or axial shift) on the imaging properties of the pseudophakic eye after implantation of aspherical intraocular lenses.
