To evaluate visual outcomes and patient satisfaction after toric multifocal intraocular lens (IOL) implantation in patients with cataract and corneal astigmatism.
University Eye Clinic Maastricht, The Netherlands.
Cohort study.
Patients with cataract, corneal astigmatism, and a motivation for spectacle independency had cataract surgery with implantation of a toric diffractive multifocal IOL (AT Lisa). Three months postoperatively, the uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities; corrected distance, intermediate, and near visual acuities; residual refractive astigmatism; defocus curve; contrast sensitivity; and patient satisfaction were evaluated.
Forty-five eyes of 25 patients were enrolled. Postoperatively, the mean UDVA was 0.04 logMAR ± 0.15 (SD) and 98% of eyes achieved a UDVA of 20/40 or better. The mean UNVA was 0.20 ± 0.16 logMAR and the mean UIVA (at 60 cm), 0.40 ± 0.16 logMAR. Residual refractive astigmatism of -1.00 diopter or less was achieved in approximately 90% of eyes. Contrast sensitivity levels were high. Approximately 50% of patients reported moderate glare, halos, and starburst symptoms. Spectacle independency for distance and near vision was achieved by 95% of patients and 79% of patients, respectively.
Toric IOL implantation in patients with cataract and corneal astigmatism provided good distance and near visual outcomes and acceptable intermediate visual outcomes, allowing patients with considerable amounts of corneal astigmatism to achieve spectacle independence at distance and near.

评估白内障合并角膜散光患者行散光矫正型多焦点人工晶状体（IOL）植入术后的视觉效果和患者满意度。

队列研究。
患有白内障、角膜散光且有摆脱眼镜需求的患者接受白内障手术，并植入散光矫正型衍射多焦点 IOL（AT Lisa）。术后 3 个月，评估未矫正远视力（UDVA）、中间距离视力（UIVA）、近视力（UNVA）；矫正远视力、中间距离视力、近视力；残余屈光性散光；离焦曲线；对比敏感度；以及患者满意度。
共纳入 25 例（45 只眼）患者。术后平均 UDVA 为 0.04 对数视力（logMAR）±0.15（标准差），98%的眼术后 UDVA 达到 20/40 或更佳。平均 UNVA 为 0.20 ± 0.16 logMAR，平均 UIVA（60cm 处）为 0.40 ± 0.16 logMAR。约 90%的眼残余等效球镜散光为 -1.00 屈光度或以下。对比敏感度水平较高。约 50%的患者报告有中度眩光、光晕和星爆症状。95%的患者达到远距和近距视力脱镜，79%的患者达到近距视力脱镜。
白内障合并角膜散光患者行散光矫正型 IOL 植入术可获得良好的远、近视力效果，且有可接受的中距视力效果，使有大量角膜散光的患者能够实现远距和近距的脱镜。
