PURPOSE To compare the visual performance of mix-and-match implanted bifocal intraocular lenses (IOLs) and bilateral implanted trifocal IOLs from the same manufacturer with the same IOL platform after femtosecond laser-assisted cataract surgery (FLACS). METHODS This prospective, comparative, non-randomized study included patients who underwent FLACS (LenSx; Alcon Laboratories, Inc., Fort Worth, Texas) with bilateral implantation of bifocal IOLs (ReSTOR +2.50 D/+3.00 D; Alcon Laboratories, Inc.) or trifocal IOLs (PanOptix; Alcon Laboratories, Inc.). Visual acuities, manifest refraction, defocus curve, contrast sensitivity, quality of life measured by the Visual Function Index (VF-14), and spectacle independence were assessed at 6 months after surgery. RESULTS A total of 70 eyes of 35 patients were included in this study. There was no difference in patient demographics and preoperative measurements between groups (P > .05). There was no difference in uncorrected distance visual acuity and corrected distance visual acuity outcomes between groups (P > .05), but uncorrected intermediate visual acuity and uncorrected near visual acuity outcomes were significantly better in the PanOptix group (P < .01). Correspondingly, the binocular defocus curve of the PanOptix IOLs showed significantly better visual acuity between -1.00 and -3.00 diopters compared to the ReSTOR IOLs (P < .05). The PanOptix group showed higher contrast sensitivity scores than the ReSTOR group for 12 and 18 spatial frequencies in photopic conditions and for 18 spatial frequencies in mesopic conditions (P < .05). The average VF-14 score was similar between groups (P = .78). None of the patients required spectacles. CONCLUSIONS Bilateral implanted PanOptix IOLs seem to provide better intermediate and near vision, defocus curve, and contrast sensitivity compared to mix-and-match implanted ReSTOR IOLs. However, similar vision-related quality of life and spectacle independence were achieved with both IOLs. [J Refract Surg. 2019;35(9):559-564.].

飞秒激光辅助白内障手术后混合搭配植入的双焦点人工晶状体和双侧植入的三焦点人工晶状体的比较。

目的比较飞秒激光辅助白内障手术（FLACS）后，来自同一制造商，同一IOL平台的混合匹配植入式双焦点人工晶状体（IOL）和双边植入的三焦点人工晶状体的视觉性能。方法这项前瞻性，比较性，非随机性研究包括接受FLACS（LenSx; Alcon Laboratories，Inc.，Fort Worth，Texas）并接受双焦点IOL双边植入（ReSTOR +2.50 D / + 3.00 D; Alcon Laboratories，Inc.）的患者。 ）或三焦点IOL（PanOptix； Alcon Laboratories，Inc.）。在术后6个月评估视力，明显的屈光度，散焦曲线，对比敏感度，通过视觉功能指数（VF-14）测量的生活质量和眼镜独立性。结果本研究共纳入35例患者的70只眼。两组之间的患者人口统计学和术前测量无差异（P> .05）。两组之间的未矫正远视力和矫正远视力结果没有差异（P> .05），但PanOptix组中未矫正的中间视力和未矫正的近视力结果明显更好（P <.01）。相应地，与ReSTOR IOL相比，PanOptix IOL的双眼散焦曲线在-1.00至-3.00屈光度之间显示出更好的视敏度（P <.05）。对于在明视条件下的12和18个空间频率以及在中视条件下的18个空间频率，PanOptix组显示出比ReSTOR组更高的对比度敏感度评分（P <.05）。各组之间的VF-14平均得分相似（P = 0.78）。没有患者需要戴眼镜。结论与混合匹配植入的ReSTOR IOL相比，双侧植入的PanOptix IOL似乎提供了更好的中，近视力，散焦曲线和对比度敏感度。然而，两种人工晶体都实现了与视觉有关的生活质量和眼镜独立性。[J Refract Surg。2019; 35（9）：559-564。]。
