Abstract

Abstract: : Purpose: A lot of new intraocular multifocal IOLs (MIOLs) , with different concepts are now available. An artificial model eye was used to show the optical properties of the investigated lenses. Methods: In a standardized model eye (EN/ISO 11979–2) the following MIOLs were evaluated: the *Acri.Twin Set (Acritec), the ArrayII (AMO), the MF4 (IOLtech) and the ZM001 (AMO). The point spread function (PSF) in the near and distance focus and the through focus response were evaluated. Further the halo intensities in the distance and near focus were examined. Results: The modulation transfer function (MTF) in the distance and near focus, the TFR and the halo intensities will be diagrammed. MIOLs with an asymmetric light distribution showed advantages in the stronger weighted focus. MIOLs with a diffractive lens design were advantageous over lenses with a refractive lens design. Conclusions: The stronger weighted focus and the diffractive lens design showed a better image quality of the investigated focal point.
