Cumulative data
Proven biomechanics and biomaterial helps to ensure minimal
rotation — less than 4˚ average rotation six months after
implantation.1,2
❚❚ STABLEFORCE® haptics keep the AcrySof® IQ Toric IOL highly
stable and centered in the capsular bag2
❚❚ Flexible haptic design provides optimal placement in capsular
bag, regardless of size2
❚❚ AcrySof® lens material binds to fi bronectin, ensuring adhesion to
the anterior/posterior capsule4
The AcrySof® Single-Piece platform

Rotation (Degrees)
Generally, for every degree of IOL rotation, 3.3% of lens cylinder power is lost.
A complete loss of cylinder power can occur with a rotation of 30˚ or greater.2

Contrast Level/Condition
**Contrast sensitivity was measured using Vector Vision CSV-1000.
AcrySof® IQ IOL showed statistically significant improvement6
in mesopic contrast sensitivity over the control lens in situations with and without glare at 6 cycles per degree (cpd).
