Three to 6-month follow-up after bilateral implantation of ReSTOR aspheric +3D Thomas Kohnen, MD Department of Ophthalmology Goethe University Frankfurt am Main, Germany Visiting Professor, Cullen Eye Institute Baylor College of Medicine, Houston, TX, USA This research was supported by Alcon Laboratories, Inc., but Dr Kohnen has no financial interest in the products presented. Methodology Twenty candidates for bilateral implantation of multifocal IOLs Expressed interest in presbyopic correction Need for intermediate vision Evaluations Preoperatively and at 1, 3 and 6 months postoperative Objective measures Visual acuity Distance (high and low contrast) Intermediate (50, 60, 70 cm)

Near (40 cm and near at preferred distance) Defocus curve Subjective measures Patient questionnaires ReSTOR +3 D Multifocal IOL Central 3.6-mm apodized diffractive disk Adds +3 D at lens plane, yielding +2.5 D at the spectacle plane Of available light energy, half to near focus half to distance focus Outer refractive annulus, devoted to distance focus Mean Uncorrected Visual Acuity 6 month postoperative 40 cm 50 cm 60 cm 70 cm
