  1. 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.

  2. Methodology • Twenty candidates for bilateral implantationof 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

  3. 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

  4. Mean Uncorrected Visual Acuity 6 month postoperative 20/20, J1+ 20/25, J1 Visual acuity, Snellen & Jaeger n=17 20/32, J2 Preferred near distance = 37 ± 4 cm

  5. Intermediate UCVA at 50cm 6 month postoperative n=17

  6. Intermediate UCVA at 60cm 6 month postoperative n=17

  7. Intermediate UCVA at 70cm 6 month postoperative n=17

  8. Mean Combined UCVA 6 months postopereative Combined UCVAs: • Distance • Intermediate: 50 cm, 60 cm, 70 cm • Near at preferred distance n=17

  9. Low Contrast Acuity3 months postoperative photopic Conditions mesopic Conditions n=19 n=19

  10. Visual Disturbances 5 halo glare 4 night vision 3 average difficulty score 2 1 0 Preop 3 6 Postoperative time, months For the same 17 patients at all time pointsBased on a 5-point scale: 1 = no difficulty, 5 = severe difficulty

  11. Conclusion • Bilateral implantation with ReSTOR SN6AD1 IOLs provided patients with good vision on all measures: • Near vision • Preferred near focus was ~37 cm • Average UCVA was <0.1 logMAR, J1 or better • Depth of optimal focus spread from 40 cm to 50 cm • Intermediate vision • Average UCVAs for all intermediate distances were0.18 logMAR or better (equivalent to 20/30 Snellen, J2) • Distance vision • Good high-contrast and low-contrast visual acuity • Visual disturbances generally decreased preop to postop
