The multifocal intraocular lenses (IOLs) implantation in patient affected by concomitant ocular disorders in advanced state, is currently controversial. The purpose of this study is to present the implantation of a multifocal aspheric diffractive IOL (the Acrysof ReSTOR SN6AD3) in a 2 year-old patient affected by congenit cataract. Aside from the phacoemulsification procedure with following implantation of the IOL, an anterior vitrectomy has been performed. Thanks to orthoptic rehabilitation with occlusion of the contralateral eye, a recovery of 2-3 decimals in visual acuity for distance and 4-5 Jaeger for near. Patient with visual impairment can benefit from the utilization of multifocal IOLs, after further accurate diagnostic case-by-case, thanks to magnification of the reading field and a minor surgical myopia. Findings registered so far need further confirmations through bigger case studies and utilization of more advanced technologies, such as the of the near addition from +4.00 D to +6.00 D, at least, or +8.00 D. Another technique that can be used to influence the magnification system is represented by the “polypseudophakia”. This technique is still to be evaluated in visually impaired patients.
