Purpose: The purpose of this study was to analyse whether an extended depth of focus (EDOF) monofocal intraocular lens (IOL) (TECNIS Eyhance™, Johnson&Johnson Surgical Vision, Inc., Santa Ana, CA) provides better intermediate visual acuity (VA) than another monofocal IOL (TECNIS 1-piece™, Johnson&Johnson Surgical Vision, Inc., Santa Ana, CA) from the same platform., Methods: Randomised prospective observational study. Patients who required cataract surgery in both eyes were included. Patients in one group were implanted with Tecnis 1-piece IOL and those in the other group with Eyhance EDOF monofocal IOL. One month after surgery in the second eye, we assessed the corrected intermediate VA (66 cm) and obtained defocus curves. We also explored the correlation of: high-order and spherical aberrations with intermediate VA, pupil size with intermediate VA and age with intermediate VA., Results: We analysed 30 patients (60 eyes), 15 patients in the TECNIS 1-piece group and 15 in the Eyhance group. Both groups achieved a far VA of 0.00 logMAR. In contrast, for intermediate vision, VA was better with the Eyhance EDOF monofocal IOLs (0.16 ± 0.12 LogMAR), the difference being statistically significant (p < 0.001). In addition, binocular intermediate VA was found to be significantly correlated with corneal (6 mm) RMS high-order aberrations (ρ 0.476) and Z 4 0 (ρ 0.483) with the Eyhance IOL., Conclusions: The new EDOF monofocal IOL (Eyhance) offers sufficient depth of focus to provide patients with comfortable vision without impairing far vision., (Copyright © 2020 Sociedad Española de Oftalmología.
