Abstract
AbstractThe restoration of accommodation still remains the biggest challenge of cataract surgery. The desire for real pseudophakic accommodation remains unchanged although modern multifocal lenses provide acceptable presbyopic correction and visual quality. Numerous concepts for accommodative intraocular lenses have been presented during the last decades but none of these were as successful as multifocal lenses are today. These concepts can be divided into three principles: Optic shift moves a single lens or a set of lenses along the optical axis such as the, for example, the 1CU (HumanOptics), the Crystalens (Bausch & Lomb) and the Synchrony (Visiogen/AMO). Varying radius of curvature changes refraction oft he lens such as, for example, the Juvene (LensGen). Replacement of the or refilling of the capular bag remains an interesting option but refilling has not reached the stage of human clinical trials. We will present an overview on the various concepts for the restoration of accommodation in the pseudophakic eye and the current clinical status.
