This article provides an assessment of the impact of different levels of monovision upon early visual outcomes and quality of vision (QoV) following the bilateral implantation of enhanced monovision intraocular lenses (IOLs). Consecutive patients implanted bilaterally with the Rayone EMV (Rayner) were recruited. The dominant eye was targeted for emmetropia, and myopia was targeted in the nondominant eye. Patients were categorized based upon the postoperative refractive outcome in the nondominant eye as follows: Group A: -0.50 to -1.0 D ( = 40), Group B: <-1.00 = D ( = 46). Uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuity, and QoV were compared 3 months postoperatively. Binocular UIVA was 0.05 ± 0.10 and -0.01 ± 0.11logMAR ( = 0.03) in the two respective groups, and binocular UNVA was 0.23 ± 0.09 and 0.14 ± 0.09logMAR ( < 0.001). Day QoV was 8.77 ± 1.33 and 8.13 ± 1.34 for night QoV in group A, and 8.85 ± 0.99 and 7.85 ± 1.35, respectively, in group B. Group A had a lower spectacle independence rate of 55% compared to 89.1%. This IOL provides a satisfactory range of vision with high QoV satisfaction. A postoperative refractive error of -1.0 D or more in the nondominant eye significantly improves binocular UIVA, UNVA, and spectacle independence, without negatively impacting QoV.
本文评估了不同程度的单眼视力对双侧植入增强型单眼视力人工晶状体（IOL）后的早期视觉效果和视觉质量（QoV）的影响。招募了连续双侧植入Rayone EMV（Rayner）人工晶状体的患者。优势眼目标为正视，非优势眼目标为近视。根据非优势眼术后屈光结果将患者分为以下几组：A组：-0.50至-1.0 D（n = 40），B组：<-1.00 D（n = 46）。术后3个月比较未矫正远视力（UDVA）、中视力（UIVA）和近视力（UNVA）以及QoV。两组的双眼UIVA分别为0.05±0.10和-0.01±0.11logMAR（P = 0.03），双眼UNVA分别为0.23±0.09和0.14±0.09logMAR（P < 0.001）。A组白天QoV为8.77±1.33，夜间QoV为8.13±1.34；B组白天QoV分别为8.85±0.99，夜间QoV为7.85±1.35。A组的眼镜独立率为55%，低于B组的89.1%。这种人工晶状体提供了令人满意的视力范围，QoV满意度高。非优势眼术后屈光不正为-1.0 D或更高可显著改善双眼UIVA、UNVA和眼镜独立性，且不会对QoV产生负面影响。
