Comparison of Visual Outcomes of Bilateral Dual-Technology Diffractive IOL versus Blended Enhanced Monofocal with Dual-Technology IOL

To compare clinical outcomes following implantation of Tecnis Synergy (ZFR00V) IOLs in both eyes and implantation of the Tecnis Synergy and Tecnis Eyhance (ICB00) combination in patients undergoing cataract surgery.Department of Cataract at the Hospital Oftalmológico de Brasilia(HOB).Prospective, interventional, randomized, parallel-group study.Visual acuity was similar between the two groups (95% CI < 0.1 logMAR). A superior visual acuity of ≥ 20/25 (at -2.00 to -2.50 D) was achieved in Group 1 (bilateral ZFR00V) than in Group 2 (combination of ZFR00V/ICB00). The binocular defocus curve demonstrated better visual acuity at 40 cm (-2.00D) and 50 cm (-2.50D) in Group 1 than in Group 2 (p < 0.05). Similar contrast sensitivity values were observed between the two groups. Patients in Group 1 reported higher satisfaction (completely satisfied) than those in Group 2 (p < 0.05). However, halos and glare were more pronounced in Group 1 than in Group 2 (p < 0.05).Both presbyopia-correcting IOL combinations showed similar binocular visual acuity results. Group 1 demonstrated enhanced visual acuity in the defocus curve at 40 cm (-2.00D) and 50 cm (-2.50D). Comparable contrast sensitivity outcomes were observed in both groups. Patients were more completely satisfied in Group 1 than Group 2, despite the higher frequency of postoperative nighttime halos and glare.
