Extended depth of focus intraocular (EDOF) IOLs form a bridge between single- and multifocal IOL design. This study aimed to compare clinical outcomes obtained after implanting two different optical designs of EDOF IOLs: the Mini Well Ready (SIFI Medtech, Catania, Italy) and Tecnis Symfony (Abbott Laboratories, Illinois, USA).
The retrospective observational study included 61 patients (122 eyes) who underwent bilateral implantation of the Mini Well Ready IOL (32 patients) or the Tecnis Symfony IOL (29 patients). The following preoperative and postoperative parameters were evaluated: spherical equivalent, anterior astigmatism, pupil size, monocular and binocular uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), monocular and binocular uncorrected intermediate visual acuity (UIVA) and distance-corrected intermediate visual acuity (DCIVA), monocular and binocular uncorrected near visual acuity (UNVA) and distance-corrected near visual acuity (DCNVA). In the 6 months postoperative period, defocus curve, contrast sensitivity, photopic phenomena, and posterior capsule opacification were assessed.
The patients receiving the Tecnis Symfony had slightly better monocular and binocular UDVA and CDVA than with the Mini Well Ready IOL, the differences were not statistically significant. Whereas the UIVA, DCIVA, UNVA, DCNVA, UNVA and DCNVA values were higher in the Mini Well Ready group, the differences were not significant. There were no significant between-group differences regarding the defocus curve for the vast majority of tested vergences. Dysphotopsias postoperatively were assessed at 6 months.
Patients receiving both the Mini Well Ready and Symfony IOLs had excellent visual acuity outcomes and spectacle independence.
扩展焦深人工晶状体（EDOF IOL）在单焦点和多焦点IOL设计之间架起了一座桥梁。本研究旨在比较植入两种不同光学设计的EDOF IOL（Mini Well Ready，意大利卡塔尼亚的SIFI Medtech公司；Tecnis Symfony，美国伊利诺伊州的雅培实验室）后的临床结果。
这项回顾性观察研究纳入了61例患者（122只眼），他们接受了Mini Well Ready IOL（32例患者）或Tecnis Symfony IOL（29例患者）的双侧植入。评估了以下术前和术后参数：等效球镜度、前散光、瞳孔大小、单眼和双眼未矫正远视力（UDVA）及矫正远视力（CDVA）、单眼和双眼未矫正中视力（UIVA）及远矫正中视力（DCIVA）、单眼和双眼未矫正近视力（UNVA）及远矫正近视力（DCNVA）。在术后6个月期间，评估了离焦曲线、对比敏感度、明视觉现象和后囊膜混浊情况。
接受Tecnis Symfony的患者单眼和双眼UDVA及CDVA略优于接受Mini Well Ready IOL的患者，但差异无统计学意义。而Mini Well Ready组的UIVA、DCIVA、UNVA、DCNVA、UNVA和DCNVA值更高，但差异不显著。在绝大多数测试的聚散度下，两组之间的离焦曲线没有显著差异。术后6个月评估了术后眩光情况。
接受Mini Well Ready和Symfony IOL的患者都有出色的视力结果且无需佩戴眼镜。
