To evaluate the visual outcomes and patient satisfaction of two multifocal intraocular lens implantation patterns, with the decision between the two patterns being guided by the patients' choice of visual zones that best suited their lifestyle, or lifestyle zones.
This is a prospective non-randomized comparative study. The lifestyle zones of 32 consecutive age-related cataract patients (64 eyes) were investigated individually to guide the surgical decision between two multifocal intraocular lens implantation patterns. The first group (MIX) received a combined implantation of a ReZoom NXG1 lens in the dominant eye and a Tecnis ZM900 lens in the other eye. The second group (MATCH) received bilateral ReZoom NXG1 lenses. One year postoperatively, the patients were assessed for binocular uncorrected visual acuity, reading visual acuity, reading speed and depth of focus under different luminance and were surveyed for visual disturbances, satisfaction and complete spectacle independence.
According to the determination of lifestyle zones, 18 and 14 patients were included in the MIX and MATCH groups, respectively. One year postoperatively, each of the patients exhibited positive visual outcomes and lifestyle satisfaction, although there were still some differences between the two groups. Generally, patients in the MATCH group had better distance visual acuity than those in the MIX group. In contrast, patients in the MIX group had better near visual acuity, better reading acuity and better reading speed than those in the MATCH group. Between the two groups, there was no clear difference in intermediate visual acuity, and the depths of focus between the two groups were approximately equal. The results of the mean NEI-RQL-42 questionnaire score, overall satisfaction, and complete spectacle independence did not differ between the two groups.
Different multifocal intraocular lenses implantation patterns can have differing advantages and disadvantages; however, the best results with respect to visual outcome and patient satisfaction can be achieved by taking individual lifestyle zones into account.
评估两种多焦点人工晶状体植入模式的视觉效果和患者满意度，这两种模式的选择由患者对最适合其生活方式的视觉区域（即生活方式区域）的选择来指导。
这是一项前瞻性非随机对照研究。对32例连续的年龄相关性白内障患者（64只眼）的生活方式区域进行了个体调查，以指导两种多焦点人工晶状体植入模式之间的手术决策。第一组（混合组）在优势眼植入ReZoom NXG1晶状体，在另一只眼植入Tecnis ZM900晶状体。第二组（匹配组）双眼均植入ReZoom NXG1晶状体。术后一年，评估患者在不同亮度下的双眼未矫正视力、阅读视力、阅读速度和焦点深度，并调查视觉干扰、满意度和完全摆脱眼镜情况。
根据生活方式区域的确定，混合组和匹配组分别纳入18例和14例患者。术后一年，尽管两组之间仍存在一些差异，但每位患者均表现出良好的视觉效果和生活方式满意度。一般来说，匹配组患者的远视力优于混合组患者。相比之下，混合组患者的近视力、阅读视力和阅读速度优于匹配组患者。两组之间，中视力无明显差异，两组的焦点深度大致相等。两组之间的平均NEI-RQL-42问卷评分、总体满意度和完全摆脱眼镜情况的结果无差异。
不同的多焦点人工晶状体植入模式可能有不同的优缺点；然而，通过考虑个体生活方式区域，可以在视觉效果和患者满意度方面取得最佳结果。
