CORE MESSAGES The AcrySof ReSTOR IOL model SA60D3 is a pseudo-accommodative apodized diffractive one-piece foldable hydrophobic acrylic posterior chamber IOL made of the same material as the monofocal AcrySof IOL. It has a central diffractive optic region with 12 concentric diffractive zones on the anterior surface of the lens which divide the light into two diffraction orders to create two lens central part is surrounded by a region that has no diffractive structure over the remainder of the 6-mm diameter lens. The near correction is calculated at D at the lens plane resulting in approximately D at the spectacle plane. This provides 6 D of pseudo-accommodation at the 20 40 level. The diffractive structure of AcrySof ReSTOR is apodized. Distinct from other diffractive IOLs there is a gradual decrease in step heights of the 12 diffractive circular structures creating a transition of light between the foci and reducing disturbing optic phenomena like glare and halo. Current study results demonstrate excellent near visual acuity without compromising distance vision with approximately 80 of investigated patients not needing spectacles for near distance or intermediate vision. The implantation of intraocular lenses IOL into the human eye reached its 50th anniversary in 1999. Despite the major achievements in correction of the distance vision by more accurate IOL formulas and biometry instrumentation the combined near and distance correction is still not perfectly achieved 1 . Introduction of refractive and diffractive multi- or bi- focal IOLs aims to correct both distance and near vision thus being able to correct ametropia and also address presbyopia 2 . The perfect pseudo-accommodative IOL will not jeopardize quality of vision . contrast sensitivity or glare .
