Controls 20D IOLs AcrySof Natural SofPort AO B&L Alcon LI60AOV SN60AT aberration-free monofocal IOL (reference lens) SN60AT spherical monofocal IOL 20D IOLs

LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, Defocus LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, SN6AD1 = ReSTOR +3D, NXG1 = ReZoom, ZM900 = Tecnis multifocal, HD500 = Crystalens HD

LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, Defocus LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, SN6AD1 = ReSTOR +3D, NXG1 = ReZoom, ZM900 = Tecnis multifocal, HD500 = Crystalens HD

LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, Defocus LI60AOV = SofPort AO, SN60AT = AcrySof spherical, SN6AD3 = ReSTOR +4D, SN6AD1 = ReSTOR +3D, NXG1 = ReZoom, ZM900 = Tecnis multifocal, HD500 = Crystalens HD

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

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

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