AcrySof® IQ IOL Aspheric Design
Spherical aberrations can reduce image quality, especially in low-contrast situations or when the pupil is dilated.5 AcrySof® IQ IOLs feature a unique negative spherical aberration to compensate for the positive aberration of an average cornea, contributing to1,5:
- Significantly improved clarity (contrast sensitivity)
- Reduced aberrations
The residual mean ocular spherical aberration of eyes implanted with the AcrySof® IQ IOL is approximately 0.1 μm, which approaches that of a young crystalline lens.6,7 When compared to a spherical IOL control, the aspheric AcrySof ® IQ IOL showed a statistically significant reduction in spherical and total higher order aberrations.1
Clinical studies suggest that a relatively small amount of positive spherical aberration may be correlated with natural super vision (natural uncorrected visual acuity 20/15 or better).7,8

§Residual aberration of the eye equals average corneal spherical aberration (0.27 µm) minus aberration correction of the lens.
