To evaluate visual outcomes, rotational stability, patients' satisfaction, and spectacle independence after bilateral Toric extended depth of focus intraocular lens (EDOF IOL) implantation. : Prospective observational study including cataract patients with bilateral corneal astigmatism between 0.75 and 3.00 D implanted with Toric EDOF IOLs. After three months distance corrected and uncorrected visual acuity at 4 m (DCVA and UDVA), 80 cm (DCI80VA and UI80VA), 67 cm (DCI67VA and UI67VA), and 40 cm (DCNVA and UNVA), IOL stability by Toric IOL Assistant tool (Osiris T, CSO, Florence, Italy), binocular defocus curves, contrast sensitivity (CS), halometry, reading performance, and subjective and objective (Root mean square-RMS, modulation transfer function-MTF, cut-off and point-spread-function-PSF-Strehl ratio) visual quality were evaluated. : Forty eyes from 20 astigmatic patients were enrolled. Mean refractive spherical equivalent and residual cylinder were -0.21 ± 0.74 D and 0.29 ± 0.31 D, respectively. No patients needed additional surgery due to IOL rotation. Binocular UDVA, UI80VA, UI67VA, and UNVA ≤ 0.2 logMAR was found in 90%, 95%, 85%, and 80%. Distance-corrected visual outcomes have overall shown higher performances. All visual acuities at defocus curves were ≤0.125 logMAR between +0.50 D and -2.00 D. PSF-Strehl ratio, MTF cut-off, RMS were 0.26 ± 0.28, 19.82 ± 12.35, 0.31 ± 0.17. Reading analysis reached 125.42 ± 27.21 words/minute, 92.56 ± 7.82, 0.17 ± 0.15 logMAR and 0.50 ± 0.11 logRAD for mean reading speed, visual acuity score, reading acuity, and critical print size, respectively. CS was higher in photopic conditions. Subjective spectacle independence was achieved in 80% of patients. : Toric EDOF IOL showed rotational stability and reliable astigmatic correction. It provided spectacle independence and good performance from distance to near distance, reaching high patient satisfaction without undermining binocular quality of vision.
评估双眼环曲面扩展焦深人工晶状体（EDOF IOL）植入术后的视觉效果、旋转稳定性、患者满意度和摆脱眼镜依赖的情况。：前瞻性观察性研究，纳入双眼角膜散光在0.75至3.00 D之间并植入环曲面EDOF IOL的白内障患者。术后三个月，测量4米（矫正远视力和未矫正远视力，DCVA和UDVA）、80厘米（矫正近视力和未矫正近视力，DCI80VA和UI80VA）、67厘米（矫正近视力和未矫正近视力，DCI67VA和UI67VA）和40厘米（矫正近视力和未矫正近视力，DCNVA和UNVA）处的视力，使用环曲面IOL辅助工具（Osiris T，CSO，佛罗伦萨，意大利）评估IOL稳定性、双眼散焦曲线、对比敏感度（CS）、眩光测量、阅读能力以及主观和客观（均方根-RMS、调制传递函数-MTF、截止频率和点扩散函数-PSF-斯特列尔比率）视觉质量。：纳入20例散光患者的40只眼。平均等效球镜度和残余柱镜度分别为-0.21±0.74 D和0.29±0.31 D。没有患者因IOL旋转而需要额外手术。90%、95%、85%和80%的患者双眼UDVA、UI80VA、UI67VA和UNVA≤0.2 logMAR。矫正远视力总体表现更好。在+0.50 D至-2.00 D之间，所有散焦曲线处的视力均≤0.125 logMAR。PSF-斯特列尔比率、MTF截止频率、RMS分别为0.26±0.28、19.82±12.35、0.31±0.17。阅读分析的平均阅读速度、视力得分、阅读视力和临界印刷字体大小分别达到125.42±27.21字/分钟、92.56±7.82、0.17±0.15 logMAR和0.50±0.11 logRAD。明视条件下CS更高。80%的患者实现了主观上摆脱眼镜依赖。：环曲面EDOF IOL显示出旋转稳定性和可靠的散光矫正效果。它提供了摆脱眼镜依赖的能力，并且从远到近都有良好表现，在不损害双眼视觉质量的情况下达到了较高的患者满意度。
