We aimed to compare the postoperative quality of vision among patients who received extended depth of focus (EDOF), bifocal, and monofocal intraocular lens (IOL) implantation. A retrospective study was conducted, and 87 patients who underwent cataract surgery were enrolled. Patients were categorized into different groups according to IOL design, with 24, 29, and 34 individuals constituting bifocal, EDOF, and monofocal groups. Preoperative and postoperative visual acuity (VA), biometry data, refractive status, contrast sensitivity (CS), higher-order aberrations (HOAs), and a quality of vision questionnaire that consisted of 11 questions were obtained 1 month postoperatively. The Kruskal−Wallis test and Pearson’s chi-square test were applied for statistical analyses. The postoperative CDVA was better in the EDOF group than in the bifocal group (p = 0.043), and the residual cylinder was lower in the EDOF groups than in the other two groups (both p &lt; 0.05). The CS was worse in the EDOF group than in the other two groups (all p &lt; 0.05), while the spherical aberration and trefoil were lower in the EDOF group than in the bifocal group (both p &lt; 0.05). In terms of the quality of vision, the scores were better in the monofocal group than in the EDOF group in seven items (all p &lt; 0.05), and the quality of vision in the bifocal group was better than in the EDOF group in small print reading (p = 0.042). In addition, the incidence of glare was lower in the monofocal group than in the other two groups (p &lt; 0.001), while the spectacle dependence ratio was significantly higher in the monofocal group compared to the other two groups (p &lt; 0.001). In conclusion, the general quality of vision was better in the monofocal group compared to the bifocal and EDOF groups, while the spectacle dependence ratio was significantly higher in the monofocal group than in the other two groups.
