- 1. AcrySof ® IQ Toric Astigmatism IOL
- 3. Perception is different than reality………..
- 6. Toric Intraocular Lenses Why should you incorporate them into your practice?
- 10. No astigmatism 1.0 D astigmatism 2.0 D astigmatism Quality of vision is deteriorated considerably by astigmatism
- 12. AcrySof ® IQ Toric IOL Specifications
- 24. Cylinder Powers AcrySof ® IQ Toric IOL is designed to accommodate a variety of cataract patients with astigmatism.
- 25. Cylinder Powers, continued A wide range of cylinder powers means more candidates can benefit from AcrySof ® IQ Toric IOL.
- 30. Contrast Sensitivity The aspheric design of AcrySof ® IQ IOL offers improved contrast sensitivity – vital for visual performance. AcrySof ® IQ IOL showed statistically significant improvement 4 in mesopic contrast sensitivity over the control lens in situations with and without glare at 6 cycles per degree (cpd) using the Vector Vision CSV-1000 § **. *Contrast sensitivity was measured using Vector Vision CSV-1000. §At 3 cpd, there was no significant change in mesopic contrast sensitivity.
- 38. Functional Vision Study, cont’d AcrySof ® IOL aspheric design makes a difference, performing better in 34 of 36 conditions.

- Key Point With a 5-mm aperture, asphericity even more dramatically improved the MTF of the AcrySof ® IQ over its spherical Natural comparator, and the MTF of the IQ Toric is similar to the AcrySof ® IQ. Background Measured in a model eye having a simulated cornea exhibiting typical adult human spherical aberration Each trace represents the average of 10 replicate IOLs Reference Data on file, Alcon Laboratories Inc.
- Key Point With a 3-mm aperture, asphericity improved the MTF of the AcrySof ® IQ lens over its Natural comparator, and the MTF of the IQ Toric is similar to the AcrySof ® IQ. Background Measured in a model eye having a simulated cornea exhibiting typical adult human spherical aberration Each trace represents the average of 10 replicate IOLs Reference Data on file, Alcon Laboratories Inc.
- Key Point The improved MTF yielded better contrast sensitivity with the Natural-to-IQ evolution; contrast sensitivity with the IQ Toric is being tested to see whether the same trend follows. Background Study 1 (Awwad et al): 52 eyes, groupwise comparison Study 2 (Pandita et al): 120 eyes, groupwise comparison, contrast sensitivity measured using artificial pupils (contact lenses) at 4 mm and 6 mm Study 3 (Tzelikis et al): 50 eyes, intraindividual/contralateral comparison References 1.

- IQ Toric Sales Aid, Page 9 Graph More information about the study: The nighttime city driving scene employs a variety of street lights, car lights, store lights and signs to recreate the high level of ambient lighting typical under these conditions. The nighttime rural driving scene uses a minimal amount of ambient lighting. Simulated driving speeds of approximately 35 mph and 55 mph were used for the city and rural scenes, respectively. Patients were asked to detect and identify a series of targets in each scene, including white-green highway information signs, black-yellow warning signs and pedestrians. Patients were asked to respond when they saw the first target, allowing a detection distance to be recoded. Patients were then asked to respond when they could distinguish the target (e.g., what the signs say, which direction the pedestrian was walking, etc.) so that an identification distance could be recorded.
- This slide is hidden, but should be used if possible, to communicate AcrySof Toric is approved for correction of REGULAR corneal astigmatism in patients. These points are listed in the speaker notes in IOL Calculation Slide (next).
- Patient Selection (minimum criteria): 1. Regular corneal astigmatism 2. Intact capsule 3. Continuous curvilinear capsulotomy (CCC) 4. In the bag lens placement
- With my understanding of your visual needs anad based on lyour exam I believe that you are and excellent candidate for an astigmatism or premium IOL.
