The Basis Z EDOF with extended depth of focus stands representative for a new generation of presbyopia-correcting optics using Wavefront Linking technology. The non-diffractive optic design aims to achieve excellent distance and intermediate visual acuity, while minimizing visual disturbances.
Preloaded injector system – incision size of 2.2 mm
The integration into the proven Basis Z platform allows standardized procedures for efficient and safe implantation.
High Abbe number and low refractive index for an outstanding visual experience
The unique SEMTE™ material of the hydrophobic IOL contains significantly fewer microvacuoles than that observed in the Acrysof IQ IOLs.5
Less glistening contributes to fewer visual disturbances and higher visual quality.5
Wavefront Linking uses specially designed surface elements to cause continuous light energy distribution along the optical axis, resulting in higher intermediate light intensity and an elongated range of focus.
The non-diffractive optic design features a central 2 mm Wavefront Linking zone. Central refractive zones with different curvatures are linked by specially designed linking zones.
The criteria for EDOF optics have been defined according to ANSI standard Z80.35 2018 A*.
*American National Standard Institute criteria are:
The Basis Z EDOF clearly excels the criteria by a significant margin, and achieves outstanding EDOF performance through Wavefront Linking.
The subjective perception of light distortion is an indicator of visual quality. The lower the light distortion index (LDI), the better the visual quality is.
Basis Z EDOF has lower LDI values compared to other presbyopia-correcting IOLs on the market.6
