  1. Clinically Relevant Advantages in the Functional Performance of the AcrySof® IQ IOL Robert P. Lehmann, MD, FACS Lehmann Eye Center, Nacogdoches, Texas Clinical Associate Professor of Ophthalmology Baylor College of Medicine, Houston, Texas Financial Disclosure: Consultant for Alcon, Travel Honorarium

  2. AcrySof® Natural IQ IOL Model SN60WF • Design Properties • Aspheric posterior surface • Designed to counteract the positive spherical aberration of an average cornea • AcrySof® Natural IOL material • Foldable, single-piece platform • Monarch® II IOL Delivery System • High refractive index (1.55)

  3. AcrySof IQ Substudy Design • A prospective, randomized, multi-center, observer- and patient-masked study • 75 subjects contralaterally implanted • Aspheric IOL: AcrySof® Natural SN60WF (IQ IOL) • Spherical IOL: AcrySof® SA60AT (Control IOL) • Functional performance substudy • Contrast Sensitivity, n=45 subjects (FACT™, Mesopic Conditions @ 3 and 6 cd/m2, with & without glare) • Night Driving Simulator, n=44 subjects (Vision Sciences Research Corporation, San Ramon, CA) • Data captured at a minimum ofthree monthsafter 2nd eye implant

  4. Mean Contrast Sensitivity Mesopic Conditions, FACT™ Chart * *

  5. Driving Simulator • Night Driving Simulation • Measured detection and identification distances • Detection= first sight of target • Identification= distinguish the target (what does the sign say, which direction is the pedestrian walking) • Series of targets • Road warning signs • Text signs • Pedestrian • Driving scenarios • Nighttime City (with streetlights) • Rural (with low beam headlights) • Simulated driving speeds • ~35 mph for city scenes • ~55 mph for rural scenes • Driving conditions • Glare • Haze (fog) • Normal Rural Scene City Scene

  6. Mean Intra-individual Differences inCity DetectionDistances, SN60WF vs SA60ATMinimum of 90 days following second eye implant N=44

  7. Mean Intra-individual Differences in City IdentificationDistances, SN60WF vs SA60ATMinimum of 90 days following second eye implant *

  8. Mean Intra-individual Differences inRural DetectionDistances, SN60WF vs SA60AT Minimum of 90 days following second eye implant * * *

  9. Mean Intra-individual Differences in Rural IdentificationDistances, SN60WF vs SA60ATMinimum of 90 days following second eye implant

  10. NDS Summary • Distance differences favoring the SN60WF IOL resulted in clinically relevant advantages in the amount of time to react to targets (>0.5 seconds) under certain conditions • City Detection: • Fog (Pedestrian*) • Glare (Pedestrian*) • City Identification: • Fog (Pedestrian*) • Glare (Text* & Pedestrian*) • Rural Detection: • Fog (Pedestrian & Warning*) • Glare (Text, Pedestrian*, & Warning*) • Normal (Pedestrian & Warning) • Rural Identification: • Fog (Warning*) • Glare (Warning*) • Normal (Warning*) *Statistically significant (p<0.05) in favor of SN60WF

  11. Conclusions • The AcrySof® IQ IOL (SN60WF) demonstrated superior functional performance in contrast sensitivity and the night driving simulator compared to the control IOL • Statistically significant differences in mesopic mean contrast sensitivity at 3 & 6 cpd w/o glare (FACT) • Statistically significant mean distance differences in favor of the SN60WF IOL • Clinically relevant advantages in the amount of time to react to targets • May improve patient safety under low visibility conditions
