Clinical Outcomes after Bilateral Implantation of Trifocal Diffractive Intraocular Lenses and Extended Depth of Focus Intraocular Lenses

The purpose of this retrospective study is to investigate clinical outcomes of bilateral implantation of diffractive trifocal intraocular lenses (IOLs) and extended depth of focus IOLs in Koreans. The clinical outcomes of cataract surgery with bilateral implantation of PanOptix, FineVision, Symfony, and MiniWell were evaluated. Uncorrected distant, intermediate (80 cm, 60 cm), near (40 cm) visual acuity, defocus curve, manifest refraction, contrast sensitivity, and higher-order aberrations, quality of vision, spectacle independence, and subjective satisfaction at postoperative 3 months were assessed. A total of 136 eyes in 68 patients were included in the analyses. PanOptix and FineVision performed better visual acuity compared to Symfony and MiniWell at 40 cm distance. Defocus curve showed broad range of vision in PanOptix and FineVision with visual acuity of more than 0.1 logarithm of the minimum angle of resolution at -2.5 diopter (D) of defocus power, while Symfony and MiniWell presented excellent intermediate vision without a dip at defocus power of -0.5 D to -1.0 D. Glare, halo, and starburst were significantly less in MiniWell compared to others. In conclusion, all four IOLs presented satisfactory clinical outcomes. PanOptix and FineVision provided good near and intermediate vision, while Symfony and MiniWell provided good intermediate vision. MiniWell induced little dysphotopsia.
