PURPOSE: To evaluate and compare visual performance of two enhanced monofocal intraocular lenses (IOLs), XY1-EM (Vivinex Impress, Hoya) and DIB00V (TECNIS Eyhance, Johnson & Johnson) with that of a conventional monofocal IOL, XY-1 (Vivinex, Hoya). SETTING: Kamiamakusa General Hospital, Kumamoto, Japan. METHODS: A retrospective analysis was conducted on 130 eyes from 75 patients, including 46 eyes (27 patients) implanted with XY1-EM, 47 eyes (26 patients) with DIB00V, and 37 eyes (22 patients) with XY-1. RESULTS: Corrected-distance visual acuity was comparable across all three groups. Both enhanced monofocal IOLs (XY1-EM and DIB00V) demonstrated significantly superior distance-corrected visual acuity at 70 cm and 50 cm compared to the conventional monofocal IOL (XY1). The rates of spectacle independence were also significantly higher in the enhanced monofocal IOL groups. In a direct comparison between the two enhanced monofocal IOLs, XY1-EM exhibited a significantly better defocus curve at -1.5D than DIB00V. Patients reported higher subjective satisfaction for "reading a newspaper" and "speed of adaptation to daily vision" in the XY-1 group compared to the DIB00V group. CONCLUSIONS: The new enhanced monofocal IOL, Vivinex Impress XY1-EM, demonstrated significantly improved intermediate visual acuity compared to the conventional monofocal IOL. It also showed slightly superior intermediate visual acuity and higher subjective satisfaction compared to the other enhanced monofocal IOL evaluated in this study.
