Visual Performance When It’s Needed Most

The Aspheric Design of the AcrySof® IQ Aspheric IOL Results in Improved Clarity and Image Quality

The Reassurance of Excellent Image Quality

Proven to deliver excellent visual performance in even the most challenging situations, the AcrySof® IQ Aspheric IOL provides the confidence of:

  • Reduced spherical and total order aberrations1
  • Improved functional vision in all conditions1
  • Increased mesopic contrast sensitivity1
  • Over 50 million implants worldwide

Aspheric Design

After analyzing more than 700 corneas,2 the AcrySof® IQ Aspheric IOL was engineered with a negative spherical aberration to compensate for the positive aberration of an average cornea. This aspheric design results in dramatically improved clarity and image quality with reduced aberrations.

Image Quality2

The AcrySof® IQ Aspheric IOL delivers a mean ocular spherical aberration of approximately 0.1 μ. When compared to a spherical IOL control, the AcrySof® IQ Aspheric IOL showed a statistically significant reduction in spherical and total higher order aberrations.1

Nighttime Driving2

Driving at night is a common cause of anxiety among cataract patients. Adding obstacles such as fog, glare, and high speeds represents an even greater risk. Under similar conditions when measured against a control lens, the AcrySof® IQ Aspheric IOL:

  • Performed functionally better in 34 of 36 conditions
  • Improved functional vision under real-world challenges
  • Allowed patients more time to take appropriate action

A subset of patients underwent testing in a validated night driving simulator. Patients were tested monocularly under conditions that simulated city and rural settings under normal, glare, and fog conditions.

AcrySof® IQ Aspheric IOL patients had an average increase of 130+ feet (vs the control lens) in which to stop after identifying a warning sign.

 

Contrast Sensitivity

The AcrySof® IQ Aspheric IOL is engineered to excel in low-light conditions, improving contrast sensitivity and functional vision for patients when they need it most.1
