Multifocal Intraocular Lenses: AcrySof ReSTOR® SN6AD2 + 2.5 D Lens
The AcrySof ReSTOR® +2.5 D is a multifocal intraocular lens (IOL) available since 2012. The IOL structure has a monofocal central area that ensures a high passage of light for distance vision and an apodized diffractive region with seven concentric rings. In this chapter, we review the current literature and our clinical experience in terms of visual acuity at different distances, quality of vision, and patient satisfaction. These results are also compared with those of other multifocal IOLs, comprising the previous model AcrySof ReSTOR® +3 D. The current increasing demand by cataract patients to be spectacle-free following surgery has increased the need for different types of multifocal IOLs. The AcrySof ReSTOR® +2.5 D is ideal for patients who require a good range of vision at intermediate distances without sacrificing the quality and quantity of distance vision.
