10. REZ = ReZoom, TEC = Tecnis multifocal, CLH = Crystalens HD
Cross-correlation coefficients (CCC) between the perfect and actual images were computed
as an image quality metric to quantify image quality and are ranged from 0 (worst) to 1 (best).
SAO = SofPort AO, ASS = AcrySof spherical, RS4 = ReSTOR +4D, RS3 = ReSTOR +3D,
REZ = ReZoom, TEC = Tecnis multifocal, CLH = Crystalens HD

11. Summary Image Quality for Distant Objects
4 mm Pupil
SAO > ASS ≈ CLH > RS4 ≈ RS3 > TEC > REZ
Image Quality for Intermediate Objects
4 mm Pupil, ~ 1 D
CLH > TEC ≈ ASS > SAO ≈ REZ > RS4 ≈ RS3
Image Quality for Near Objects of Multifocal IOLs
3 mm Pupil
RS3 > TEC ≈ REZ > RS4
Working Distance for Near Objects of Multifocal IOLs
RS4 ≈ TEC < REZ < RS3
SAO = SofPort AO, ASS = AcrySof spherical, RS4 = ReSTOR +4D, RS3 = ReSTOR +3D,
REZ = ReZoom, TEC = Tecnis multifocal, CLH = Crystalens HD

12. Conclusion
Different premium IOLs have their own optical characteristics. Therefore, selection of premium IOLs should be based on the understanding of optical properties.
