Abstract

We aimed to compare the visual outcomes associated with different postoperative spherical equivalents (SEs) following trifocal intraocular lens implantation in patients with cataracts across different refractive states. This study included 156 eyes of 100 patients. The corrected distance visual acuity, uncorrected distance visual acuity, uncorrected intermediate visual acuity, uncorrected near visual acuity, SE, defocus curve, visual quality and satisfaction were compared postoperatively. For non-axial myopia, group B showed better visual acuity at + 0.5 D and + 1.0 D (P = 0.013 and P < 0.001), but worse visual acuity at -3.5 D and − 4.0 D defocus (P = 0.013 and P = 0.004), with better far vision satisfaction (P = 0.030). For mild to moderate axial myopia, group A showed worse visual acuity at + 0.5 D defocus (P = 0.006) and + 1.0 D (P < 0.001). For high axial myopia, the postoperative UNVA was better in group A (P = 0.010). Group A exhibited better visual acuity at -3.0 D, -3.5 D and − 4.0 D (P = 0.018, P = 0.002 and P < 0.001), but worse visual acuity at + 0.5 D and + 1.0 D (P = 0.002 and P < 0.001), with a higher near vision satisfaction (P = 0.021). Trifocal IOLs can provide good visual outcomes. In patients with non-axial myopia, residual emmetropia to mild hyperopia SE may be associated with better far vision satisfaction. For patients with high axial myopia, residual myopia SE may be associated with better UNVA and improved near vision satisfaction, not affecting distant or intermediate vision satisfaction.
