To evaluate the visual performance after bilateral implantation of a toric diffractive aspheric multifocal intraocular lens (IOL) with a +2.17 diopters (D) (60 cm) intermediate and a +3.25 D (40 cm) addition (add) power.
This prospective single-arm study was conducted at the Department of Ophthalmology, Goethe University, Frankfurt, Germany. Twenty-five patients (50 eyes) received bilateral implantation of the toric PanOptix IOL (AcrySof IQ PanOptix; Alcon Research LLC) before enrollment. Exclusion criteria were previous ocular surgeries excluding lens surgery and ocular pathologies or corneal abnormalities. Examination at 3 months postoperatively included manifest refraction; monocular and binocular uncorrected distance (UDVA) and distance-corrected (DCVA) visual acuity at 4 m and 80, 60, and 40 cm; and slit-lamp examination. At 3 months postoperatively, monocular and binocular defocus, binocular contrast sensitivity under photopic and mesopic conditions, and optical phenomena, and spectacle independence were evaluated.
Mean refractive spherical equivalent was 0.12 ± 0.380 D and mean refractive cylinder was -0.21 ± 0.237 D at 3 months postoperatively. A significant decrease in refractive cylinder was observed postoperatively (P < .05), with 98% showing a postoperative astigmatism below 0.75 D. Monocular UDVA was better than 0.14 logMAR in all distances. Binocular defocus curve showed peaks at 0.00 D (-0.09 logMAR) and -1.50 and -2.00 D (-0.02 and 0.00 logMAR). The worst values between far (4 m) and near (40 cm) distance were 0.04 logMAR at -1.00 D. Despite some optical phenomena, 92% of patients would choose the same IOL again and recommend it to others.
The visual performance of the toric PanOptix IOL showed good visual acuity at all distances; more than 90% achieved a decrease of refractive cylinder below 0.75 D, high patient satisfaction despite some optical phenomena, and high spectacle independence 3 months postoperatively.

评估植入具有 +2.17 屈光度（D）（60 cm）中间焦度和 +3.25 D（40 cm）附加屈光度的双焦散光非球面多焦点人工晶状体（IOL）后的视觉性能。
这项前瞻性单臂研究在德国法兰克福歌德大学眼科进行。25 名患者（50 只眼）在入组前接受了双焦散光 PanOptix IOL（AcrySof IQ PanOptix；爱尔康研究有限责任公司）的双侧植入。排除标准为既往眼部手术（不包括晶状体手术）以及眼部病变或角膜异常。术后 3 个月的检查包括显验光；4 m 及 80、60 和 40 cm 处的单眼和双眼未矫正远视力（UDVA）以及矫正远视力（DCVA）；以及裂隙灯检查。术后 3 个月时，评估单眼和双眼散焦、明视和暗视条件下的双眼对比敏感度、光学现象以及是否不再依赖眼镜。
术后 3 个月时，平均等效球镜度为 0.12 ± 0.380 D，平均柱镜度为 -0.21 ± 0.237 D。术后观察到柱镜度显著降低（P < 0.05），98% 的患者术后散光低于 0.75 D。所有距离的单眼 UDVA 均优于 0.14 logMAR。双眼散焦曲线在 0.OD（-0.09 logMAR）以及 -1.50 和 -2.00 D（-0.02 和 0.00 logMAR）处出现峰值。远距（4 m）和近距（40 cm）之间最差值在 -1.00 D 时为 0.0 logMAR。尽管存在一些光学现象，但 仍有 92% 的患者会再次选择相同的人工晶状体并推荐给他人。
双焦散光 PanOptix IOL 的视觉性能在所有距离均显示出良好的视力；超过 90% 的患者柱镜度降低至 0.75 D 以下，尽管存在一些光学现象，但患者满意度较高，且术后 3 个月对眼镜的依赖程度较低。[《屈光手术杂志》。2020；36(10):638 - 644。]
