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.

  • Toric Intraocular Lenses Why should you incorporate them into your practice?
    • We have to meet or exceed our patients demands for excellent vision
    • Knowing what is available and how to use it is critical to your practice success
    • Cataract surgery is your patients opportunity to enhance their vision lifestyle
    • Astigmatism and premium IOLs are available to meet these expectations.
  • The Question now is….
    • Why is it in life that you would never give glasses without correcting the patients astigmatism, but when I do cataract (now) surgery I don’t fix it?
    • How do we treat it?
    So What About Astigmatism? Vision without astigmatism Vision with astigmatism 1.5D cyl @ 90 Vision with astigmatism 3.0D cyl @ 90
  • No astigmatism 1.0 D astigmatism 2.0 D astigmatism Quality of vision is deteriorated considerably by astigmatism

    • †† AcrySof ® Single-Piece (SA60AT)
  • Rotational Stability IOL rotation can have significant impact on astigmatism correction.
    • Generally, for every 1º of IOL rotation, 3.3% of lens cylinder power is lost 2 .
    • A complete loss of cylinder power can occur with a rotation of >30º 2 .
  • Rotational Stability, continued AcrySof ® IQ Toric IOL ensures minimal rotation – less than 4º average rotation 6 months after Implantation 1,2 .
    • 81.1% of patients were ≤5º of intended axis 2 .
    • 97.1% of patients were ≤10º of intended axis 1 .
    • Rotational Stability, continued
    • Proven biomechanics and biomaterial ensure
    • AcrySof ® IQ Toric IOL stays right where you want it.
    • STABLEFORCE ® haptics keep IOL highly stable and centered in capsular bag 2 .
    • Flexible haptic design provides optimal placement in capsular bag, regardless of size 2 .
    • AcrySof ® lens materials binds to fibronectin.
      • Ensures adhesion to anterior/ posterior capsule 3
  • Cylinder Powers AcrySof ® IQ Toric IOL is designed to accommodate a variety of cataract patients with astigmatism.
  • Cylinder Powers, continued A wide range of cylinder powers means more candidates can benefit from AcrySof ® IQ Toric IOL.
    • Benefits of AcrySof ® Aspheric Optics
    • Clinical improvements demonstrated over spherical control lens:
    • Improved Functional vision
    • Increased Contrast Sensitivity
    • Reduction of spherical aberration and total high order aberrations (HOAs)
    • This region of defocused light can reduce image quality.
    Spherical Aberration The Problem: Occurs when light rays are over-refracted at periphery of optics.
    • This results in enhanced clarity and image quality.
    Aspheric Optics The Solution: Negative spherical aberration aligns the light rays to compensate for positive spherical aberration.
  • Reduction in Spherical Aberrations
    • AcrySof ® IQ Toric IOLs aspheric design** offers statistically significant reduction in both spherical and total higher order aberrations 4 .
     Differences favor AcrySof ® IQ IOL overall and at each visit ( p <0.0001).
  • 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.

    • AcrySof ® IQ Aspheric IOLs
    • With the spheric to aspheric monofocal IQ evolution,
      • MTF improved (shown here)
      • Contrast sensitivity under mesopic conditions improved 1-3

    • aberration result in vision similar to a young,
    • natural crystalline lens.
    • Spherical aberration in human eyes:
      • 0.08 microns for populations with normal vision 5 .
    • AcrySof ® IQ IOL:
      • Corrects about .20 microns of spherical aberration.
      • Designed to leave a residual ~0.08 microns.
    • AcrySof ® IQ Toric IOL is designed with a similar
    • level of spherical aberration correction.
  • Contrast Sensitivity, continued AcrySof ® IQ IOL improves contrast sensitivity in both well-lit and low-light conditions 4 .
    • Virtually the same image quality** whether aperture size is 3 or 5 mm.
    • Image quality was characterized by measuring modular transfer function (MTF) in a model eye utilizing simulated cornea with typical adult human spherical aberration.
  • Improved Functional Vision
    • The aspheric design of the AcrySof ® IQ IOL
    • provides improved functional vision in
    • challenging, low-visibility environments .
    • Allows patients to more quickly detect and identify objects.
    • Allows for greater reaction time.
    • May increase patient safety.
  • Functional Vision Study
    • Patients were tested monocularly in a night driving simulator in simulated city and rural settings under normal, glare and fog conditions.
    • Patients with AcrySof ® IQ IOL performed functionally better than the control lens in 34 of 36 conditions tested 4 .

      • Completed while the IOL is unfolding in the capsular bag
      • Can be rotated after IOL has unfolded, if needed, but take care to have capsular bag inflated with OVD
  •  
  • IOL Alignment
    • II. Stabilize IOL During OVD Removal
      • Take care to prevent IOL from rotating past intended axis during OVD removal
        • 2 nd instrument
        • Silicone I/A tip
  •  
  • IOL Alignment
    • III. Final Alignment
      • Carefully rotate IOL clockwise onto the intended axis of alignment
      • Tap IOL down into capsular bag to seat lens in place
  •  
  • Discussion points
    • Show them the astigmatism and take it out of the phoropter
    • Use a vision questionnaire to determine their spectacle needs
  • They are your patient, they love you!
    • This is an opportunity to educate them about their visual function and get to know them better.
    • Use of a portable DVD in your practice is a great option!
      • Educational DVDs are free
      • Eyemaginations
    • Financing options
    • 1.50 dioptors or more equals Toric in my practice (experience from multifocals)
  • Dealing with the unhappy patient
    • I have very few in this group!
    • Patients accept residual astigmatism
    • 20/Happy!
  • Discussion points
    • LASIK enhancements are an option
    • Toric outcomes for FDA is much better than LASIK and PRK
    • “ I would never give you a spectacle or contact lens prescription that did not treat your astigmatism.”
  • Practice builder for you….
    • 90% of LASIK patients buy an expensive pair of sunglasses
    • Options of plano progressive lenses.
    • If they are happy they are going to tell other patients about your practice!
    • Reimbursement is $110.00/eye in addition to standard co-management reimbursement through insurance (~150.00).
  • Summary
    • This astigmatism type Premium IOL is very forgiving!
    • All you have to say is, “You have a lot of astigmatism! Your surgeon is going to discuss with you about your astigmatism and ways to address it.”
