Abstract：
OBJECTIVE: To evaluate visual outcomes and patient-reported results after bilateral femtosecond-laser assisted refractive lens exchange (RLE) with the implantation of a diffractive trifocal intraocular lens (IOL).
METHODS: Prospective interventional case series METHODS: A study of 27 patients (54 eyes) implanted with the Clareon PanOptix (Alcon) multifocal IOL during femtosecond laser assisted RLE in a university hospital setting. The uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 60cm, uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 40cm and 33cm were evaluated at three months postoperatively and compared with the preoperative values. In addition, we assessed the postoperative defocus curve, mesopic and photopic contrast sensitivity, and patient-reported spectacle independence.
RESULTS: The mean postoperative binocular UDVA was -0.02±0.06 logMAR and CDVA was -0.11±0.05 logMAR. The UIVA was -0.07±0.05 logMAR and DCIVA was -0.07±0.07 logMAR. The UNVA at 40cm was 0.03±0.09 logMAR and DCNVA was -0.02±0.06 logMAR; and, at 33cm UNVA was 0.14±0.10 logMAR and DCNVA was 0.11±0.08 logMAR. In comparison to the preoperative binocular CDVA (-0.12±0.08 logMAR), no statistically significant change was observed (p=1.0), while all the other binocular visual acuities improved (p<0.01). In the mean binocular defocus curve, the visual acuity was better than 0.10 logMAR in the range between +0.5 D and -3.0 D. The mean contrast sensitivity was within the normal range, and most patients reported complete spectacle independence.
CONCLUSIONS: The RLE surgery improved uncorrected visual acuity at far, intermediate and near distances without negatively affecting the CDVA. Patients achieved a high level of spectacle independence.

摘要：
目的：评估双侧飞秒激光辅助屈光晶状体置换（RLE）并植入衍射三焦点人工晶状体（IOL）后的视觉结果和患者报告的结果。
方法：前瞻性介入病例系列方法：在大学医院环境中，对27例患者（54只眼）在飞秒激光辅助RLE期间植入ClareonPanOptix（Alcon）多焦点IOL的研究。未矫正（UDVA）和矫正（CDVA）的远距视力，未矫正（UIVA）和距离矫正（DCIVA）的中间视力在60cm，术后3个月评估未矫正（UNVA）和距离矫正（DCNVA）近视力40cm和33cm，并与术前值进行比较。此外,我们评估了术后散焦曲线，介视和明视对比敏感度，和患者报告的眼镜独立性。
结果：术后平均双眼UDVA为-0.02±0.06logMAR，CDVA为-0.11±0.05logMAR。UIVA为-0.07±0.05logMAR,DCIVA为-0.07±0.07logMAR。40cm处的UNVA为0.03±0.09logMAR，DCNVA为-0.02±0.06logMAR；在33cm时，UNVA为0.14±0.10logMAR，DCNVA为0.11±0.08logMAR。与术前双眼CDVA（-0.12±0.08logMAR）相比，没有观察到统计学上的显着变化（p=1.0），而所有其他双眼视力均得到改善(p<0.01)。在平均双眼散焦曲线中，在+0.5D和-3.0D之间的范围内，视力优于0.10logMAR。平均对比敏感度在正常范围内，大多数患者报告完全独立眼镜。
结论：RLE手术改善了远未矫正视力，中间和近距离，而不会对CDVA产生负面影响。患者实现了高水平的眼镜独立性。
