Alcon AcrySof ReSTOR® IOL Full Range of Vision
The AcrySof® ReSTOR® Aspheric IOL Optical System
Our latest advance is designed to compensate for positive corneal spherical aberration1
Spherical Aberration with a Spherical IOL
- Spherical aberration occurs when light rays are overrefracted at the periphery of a lens system, resulting in a region of defocused light which can decrease image quality
Correction with an Aspheric Optic
- Aspheric optics align the light rays to compensate for positive corneal spherical aberration, resulting in enhanced image quality
In addition to asphericity, the AcrySof® ReSTOR® IOL features a unique optic system that merges the strengths of both apodized diffractive and refractive technologies. The AcrySof® ReSTOR® IOL uses the central apodized diffractive region and +4.0 D correction to focus a clear image on the retina for near vision, while the peripheral refractive region, also paired with the central apodized region, helps enhance distance visual acuity.
- SN6AD3 DFU. The effects of this aspheric design feature have not been clinically assessed.
