: To evaluate postoperative outcomes, spectacle dependance and the occurrence of the photic phenomena in patients after cataract surgery following the implantation of a non-diffractive extended depth of focus (EDOF) intraocular lens was compared to monofocal and multifocal lenses. We enrolled patients with bilateral cataracts who wanted to reduce their dependence on glasses in the study. They were followed for 6 months. The study group in which the EDOF lens was implanted consisted of 70 eyes in 35 patients. The control groups consisted of: 52 eyes in 26 patients in whom a multifocal was implanted and 52 eyes in 26 patients with implanted monofocal lens. After a total of 2 weeks, 2 months and 6 months post-surgery the following were evaluated: uncorrected and corrected visual acuity at 4 m, 80 cm, 40 cm, manifest refraction expressed as mean refractive spherical equivalent (MRSE), contrast sensitivity, intraocular pressure. A questionnaire on independence from ocular correction, the occurrence of photic phenomena, and patient satisfaction was also completed. : Monocular and binocular visual acuity and MRSE 6 months after the procedure were compared between three groups. All of the main analyses, except for comparisons of uncorrected distance visual acuity (both monocular and binocular) level, were significant. Contrast sensitivity was lower among patients with multifocal lens than among patients with EDOF lens. Halo and glare after 6 months were seen more often among patients with multifocal lens than among patients with the other lens (65% of eyes with multifocal lens vs. 6% of eyes with EDOF lens and 0% of eyes with monofocal lens). Glasses were needed by 35% of patients with EDOF lens, and by 96% of patients with monofocal lens and in none of the patients with multifocal lens. : Most patients qualify for the implantation of a non-diffractive EDOF lens. Post-operative visual acuity improves at any distance. The best monocular visual acuity for intermediate distances is provided by an EDOF lens, and for near distance by a multifocal lens. The EDOF lens definitely increases independence from spectacle correction compared to monofocal lenses; however, the greatest degree of independence from spectacles is provided by multifocal lenses. The incidence of photic phenomena is slightly higher than that of a monofocal lens, and much lower for a multifocal lens.
为了评估术后结果，将非衍射型扩展景深（EDOF）人工晶状体植入术后患者的视力依赖情况以及光现象的发生情况与单焦点和多焦点人工晶状体进行了比较。我们纳入了希望减少对眼镜依赖的双侧白内障患者进行研究。对他们进行了6个月的随访。植入EDOF人工晶状体的研究组由35例患者的70只眼组成。对照组包括：植入多焦点人工晶状体的26例患者的52只眼和植入单焦点人工晶状体的26例患者的52只眼。在术后总共2周、2个月和6个月时，评估以下指标：4米、80厘米、40厘米处的未矫正和矫正视力、以平均屈光球镜等效值（MRSE）表示的显验光、对比敏感度、眼压。还完成了一份关于视力矫正独立性、光现象发生情况和患者满意度的问卷。比较了三组术后6个月的单眼和双眼视力以及MRSE。除了未矫正远视力（单眼和双眼）水平的比较外，所有主要分析均具有显著性。多焦点人工晶状体患者的对比敏感度低于EDOF人工晶状体患者。术后6个月时，多焦点人工晶状体患者出现光晕和眩光的情况比其他人工晶状体患者更常见（多焦点人工晶状体眼的65% vs. EDOF人工晶状体眼的6%和单焦点人工晶状体眼的0%）。35%的EDOF人工晶状体患者需要佩戴眼镜，96%的单焦点人工晶状体患者需要佩戴眼镜，而多焦点人工晶状体患者均不需要佩戴眼镜。大多数患者适合植入非衍射型EDOF人工晶状体。术后任何距离的视力均有改善。EDOF人工晶状体在中等距离提供最佳单眼视力，多焦点人工晶状体在近距离提供最佳单眼视力。与单焦点人工晶状体相比，EDOF人工晶状体确实增加了摆脱眼镜矫正的独立性；然而，多焦点人工晶状体提供的摆脱眼镜的程度最大。光现象的发生率略高于单焦点人工晶状体，远低于多焦点人工晶状体。
