To evaluate the defocus curves of 4 presbyopia-correcting intraocular lenses (IOLs).
Department of Ophthalmology, Goethe University, Frankfurt, Germany.
Prospective case series.
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.
The UDVA and CDVA were not significantly different between groups (P > .05); however, the EDOF group had worse near CDVA (P < .001). The trifocal and EDOF groups showed better DCIVA than the panfocal and SegRef group at 80 cm (P < .001); the EDOF and panfocal groups had comparable DCIVA at 60 cm (P > .05). Defocus curves showed no significant between-group differences from 4 m to 2 m (P > .05). The EDOF group had better visual acuity from 1 m to 67 cm than the trifocal and SegRef groups and better visual acuity than the panfocal group at 1 m (P > .05). Compared with the other IOLs, the panfocal IOL yielded significantly better visual acuity at 50 cm (P < .001) and the EDOF IOL worse visual acuity at 40 cm (P < .01). There was a significant difference in spectacle independence between the panfocal group and EDOF group (P < .05) but no difference between the other groups.
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 cm.
评估 4 种矫正老视的人工晶状体的离焦曲线。
德国法兰克福歌德大学眼科系。
前瞻性病例系列。
本研究纳入双眼行散光型 PanFocal、散光型 trifocal、分段式折射（SegRef）或扩展景深（EDOF）老视矫正型人工晶状体植入术的患者。测量未矫正（UDVA）和矫正（CDVA）远视力、未矫正中间和近视力、远距矫正中间（DCIVA）和近距（DCNVA）视力、离焦曲线和离焦镜独立性。
各组间 UDVA 和 CDVA 无显著差异（P>.05）；然而，EDOF 组近距 CDVA 较差（P<.001）。与 PanFocal 和 SegRef 组相比，trifocal 和 EDOF 组在 80 cm 处的 DCIVA 更好（P<.001）；EDOF 和 PanFocal 组在 60 cm 处的 DCIVA 相当（P>.05）。从 4 m 到 2 m，离焦曲线在各组间无显著差异（P>.05）。EDOF 组从 1 m 到 67 cm 的视力优于 trifocal 和 SegRef 组，从 1 m 处的视力优于 PanFocal 组（P>.05）。与其他人工晶状体相比，PanFocal 人工晶状体在 50 cm 处的视力明显更好（P<.001），EDOF 人工晶状体在 40 cm 处的视力更差（P<.01）。PanFocal 组和 EDOF 组的离焦镜独立性有显著差异（P<.05），但其他组之间无差异。
4 种人工晶状体均提供了同样良好的 CDVA。EDOF 人工晶状体的 DCIVA 略好，但 DCNVA 比其他人工晶状体差。只有 PanFocal 人工晶状体在 50 cm 处提供更好的 DCIVA。
