Today, patients often expect to achieve spectacle independance after cataract surgery. New trifocal intraocular lenses have been developed to try and fullfill this demand. The purpose of this study is to report the short-term visual outcomes of a new trifocal intraocular lens (AcrySof PanOptix™).
Consecutive adult patients undergoing cataract surgery with bilateral implantation of the study intraocular lens in a private practice clinic were considered for inclusion. Exclusion criteria were the presence of other ocular pathologies or preoperative astigmatism >1.5 diopters (D). Patients with intraoperative complications were excluded from analysis. One month after surgery patients underwent: monocular defocus curve; monocular and binocular uncorrected visual acuity in photopic and mesopic conditions, for far (4 m), intermediate (60 cm) and near (33 cm) distances and binocular contrast sensitivity. Patients completed a visual satisfaction questionnaire between 9 and 12 months after surgery.
One hundred and sixteen eyes of fifty-eight patients receiving bilateral implantation of the study intraocular lens were analysed. Mean binocular uncorrected visual acuity in photopic conditions was 0.03 LogMAR for far, 0.12 for intermediate and 0.02 for near distances. All patients achieved a binocular uncorrected visual acuity better than 0.3 LogMAR (20/40 Snellen equivalent) for distance and near vision and 94.8% of patients for intermediate vision. Mesopic binocular uncorrected visual acuity values were similar to photopic values. The monocular defocus curves showed that the best visual acuity was reached at a vergence of 0.00D. Visual acuity dropped slightly at -1.00D and peaked again at -2.00D. Visual acuities better than 0.2 LogMAR were maintained between -2.50D and +0.50D. Contrast sensitivity was high and similar in photopic and mesopic conditions. As regards patient-evaluated outcomes, only 2 patients (3.4%) were fairly dissatisfied with their sight after surgery. Three patients (5.1%) reported the need for spectacle correction for certain activities. All other patients (94.8%) reported never using spectacle correction.
The PanOptix trifocal IOL provides good short-term visual outcomes, with good intermediate performance and excellent patient-reported satisfaction. The similar values achieved in mesopic and photopic conditions in binocular uncorrected visual acuity and contrast sensitivity suggest low pupillary dependence for light distribution.

如今，患者常常期望白内障手术后能摆脱眼镜。新型三焦点人工晶状体已被研发出来以满足这一需求。本研究旨在报告一种新型三焦点人工晶状体（AcrySof PanOptix™）的短期视觉效果。
纳入在一家私人诊所接受白内障手术并双侧植入研究用人工晶状体的成年连续患者。排除标准为存在其他眼部病变或术前散光>1.5 屈光度（D）。术中出现并发症的患者被排除在分析之外。术后 1 个月，患者接受：单眼散焦曲线；在明视和中视条件下，远（4 米）、中（60 厘米）和近（33 厘米）距离的单眼和双眼未矫正视力，以及双眼对比敏感度。患者在术后 9 至 12 个月完成视觉满意度问卷。
分析了 58 例接受双侧植入研究用人工晶状体患者的 116 只眼。明视条件下，双眼平均未矫正视力远距为 0.03 LogMAR，中距为 0.12，近距为 0.0
