This study was performed to evaluate optical quality and through focus performance

of premium intraocular lenses.

SAO = SofPort AO, ASS = AcrySof spherical, RS4 = ReSTOR +4D, RS3 = ReSTOR +3D,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).

Summary

Image Quality for Distant Objects4 mm PupilSAO > ASS ≈ CLH > RS4 ≈ RS3 > TEC > REZ

Image Quality for Intermediate Objects4 mm Pupil, ~ 1 DCLH > TEC ≈ ASS > SAO ≈ REZ > RS4 ≈ RS3

Image Quality for Near Objects of Multifocal IOLs3 mm PupilRS3 > TEC ≈ REZ > RS4

Working Distance for Near Objects of Multifocal IOLs3 mm PupilRS4 ≈ TEC < REZ < RS3
