  1. Multicentricevaluationof a newdiffractivemultifocal IOL : visualperformanceandpatients‘ satisfaction P. Vo Tan, Paris N. Jabbur, Beyrouth S. Zaluski, Perpignan P. Rozot, Marseille J. Blondel, Nice G. Grabner, Salzbourg M.H Duret, Lille D. O’Brart, Londres sfo/SAFIR maY 2011

  2. Evaluation of the DIFFRACTIVA-aAHumanOptics AG (Germany) 1-month post-op • 20 patients with bilateral cataract • Mean age 71. 8 years (44-87) • Pre-Op astigmatism ≤ 1 dpt • Incision size 2.2/2.4 mm • IOL power= 21.1 ±1.4 dpt • Multifocal, Monobloc, HydrophilicAcrylic • Diffractive asphericanterior surface • Addition of +3.5 D (IOL plane) SE Post-Op

  3. VISUAL ACUITY WITHOUT CORRECTION 1-month post-op

  4. VISUAL ACUITY WITH DISTANCE CORRECTION 1-month post-op

  5. QUESTIONNAIRE • Do you wear correcting glasses? Youngest patient (44 years) • Are you satisfied with your vision?

  6. DEFOCUS CURVE(MONOCULAR) Diff Add (HumanOptics) +3,5 0 D (n=9) AT LISA (Zeiss) Add +3,75 D (n=12)Micro F (Physiol) Add +3,50 et +1,75 D (n=5) Ongoing study M.H Duret, Lille

  7. CONTRAST SENSITIVITY(MONOCULAR) Mono (Aspira, n=30) Roessler, Küchle WOC 2010 MH Duret

  8. CONCLUSIONS • The new multifocal Diffractiva-aA provides excellent visual acuity at near and far distances as well as good intermediate distance results • The Diffractiva-aA is able to provide a high rate of spectacle independence and minimal photic phenomena at night • The excellent visual performance of the Diffractiva-aA is reflected by the high level of patients’ satisfaction

  9. CONCLUSIONS • The defocus curves show that, as expected, the trifocal micro F (Physiol) provides better intermediate vision than the two bifocal IOLs but the Diffractiva-aA outperforms the AT-LISA (Zeiss). • The contrast sensitivity curves show that the Diffractiva-aA outperforms the other MIOLs when patients are tested under mesopic conditions and there is no loss of contrast sensitivity when compared to its monofocal counterpart (Aspira)
