	abstract = {PURPOSE: To evaluate the defocus curves of 4 presbyopia-correcting intraocular lenses (IOLs). SETTING: Department of Ophthalmology, Goethe University, Frankfurt, Germany. DESIGN: Prospective case series. METHODS: Patients included in the study had bilateral surgery with implantation of diffractive panfocal, diffractive trifocal, segmental refractive (SegRef), or extended-depth-of-focus (EDOF) presbyopia-correcting IOLs. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, uncorrected intermediate and near visual acuities, distance-corrected intermediate (DCIVA) and near (DCNVA) visual acuities, defocus curve, and spectacle independence were measured. RESULTS: The UDVA and CDVA were not significantly different between groups (P\&nbsp;\&gt;\&nbsp;.05); however, the EDOF group had worse near CDVA (P\&nbsp;\&lt;\&nbsp;.001). The trifocal and EDOF groups showed better DCIVA\&nbsp;than the panfocal and SegRef group at 80\&nbsp;cm\&nbsp;(P\&nbsp;\&lt;\&nbsp;.001); the EDOF and panfocal groups had comparable DCIVA at 60\&nbsp;cm\&nbsp;(P\&nbsp;\&gt;\&nbsp;.05). Defocus curves showed no significant between-group differences from 4\&nbsp;m to 2\&nbsp;m\&nbsp;(P\&nbsp;\&gt;\&nbsp;.05). The EDOF group had better visual acuity from 1\&nbsp;m to 67\&nbsp;cm than the trifocal and SegRef groups and better visual acuity than the panfocal group at 1\&nbsp;m\&nbsp;(P\&nbsp;\&gt;\&nbsp;.05). Compared with the other IOLs, the panfocal IOL yielded significantly better visual acuity at 50\&nbsp;cm\&nbsp;(P\&nbsp;\&lt;\&nbsp;.001) and the EDOF IOL worse visual acuity at 40\&nbsp;cm\&nbsp;(P\&nbsp;\&lt;\&nbsp;.01). There was a significant difference in spectacle independence between the panfocal group and EDOF group (P\&nbsp;\&lt;\&nbsp;.05) but no difference between the other groups. CONCLUSIONS: The 4 IOLs provided equally good CDVA. The EDOF IOL yielded slightly better DCIVA but worse DCNVA than the other IOLs. Only the panfocal IOL gave better DCIVA at 50\&nbsp;cm.},
