The study found that at 3 months post-implantation, patients receiving extended depth of focus (EDOF) and multifocal (Multi) intraocular lenses (IOLs) demonstrated non-inferior uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) compared to monofocal IOLs (P > 0.05). Notably, both EDOF and Multi IOLs achieved superior uncorrected near visual acuity (UNVA) (P < 0.001). The EDOF group exhibited better uncorrected intermediate visual acuity (UIVA), while the Multi and Mono groups yielded comparable results. However, comfortable near-distance visual acuity (CNDVA) was significantly lower than UNVA across all groups, particularly in EDOF and Multi IOL recipients (P < 0.05). Overall, EDOF and Multi IOLs effectively enhanced patients’ near visual comfort and clarity, although one patient in the multi-group experienced severe fatigue, impairing tolerance.
