Higher satisfaction was found among the XY1- EM group compared to DIB00V for reading a newspaper and speed of adaptation to daily vision. Otherwise, there was no statistically significant difference between the two groups on other survey questions. Discussion In this retrospective study of 130 eyes, the authors found that an enhanced monofocal IOL, Vivinex Impress XY1-EM, provided a signifi- cantly improved range of focus compared to the conventional XY-1 monofocal IOL. Furthermore, it demonstrated somewhat higher subjective satisfaction compared to the TECNIS Eyhance DIB00V, another enhanced monofocal IOL. As expected, corrected distance visual acuity was similar among all three groups. Importantly, both enhanced monofocal groups achieved significantly higher spectacle indepen- dence than the conventional monofocal group. The enhanced monofocal lenses both performed well; however, the XY1-EM demonstrated improved intermediate vision compared to the DIB00V lens, with superior performance at –1.5 D on the defocus curve. Additionally, the XY1- EM demonstrated higher patient satisfaction Between the three groups, there was no significant difference in CDVA at 3 months post- operatively. The XY1-EM and DIB00V groups demonstrated superior intermediate CDVA at 50 and 70 cm compared to the XY-1 group (p<0.01). The defocus curve was measured for the XY1-EM and DIB00V groups; visual acuity was superior in the XY1-EM group at –1.5 D (p<0.05), although the two groups were similar at all other points along the curve. Postopera- tive manifest refractions were similar across the three groups with respect to spherical power, spherical equivalent, and prediction error, but the XY-1 group had higher cylinder power than the DIB00V group (p=0.013). Nineteen patients in the XY1-EM group, 21 in the DIB00V group, and 15 in the XY-1 group underwent bilateral surgery. Of those patients, 78.9%, 71.4%, and 53.3% were spectacle inde- pendent at the 3-month postoperative visit in the XY1-EM, DIB00V, and XY-1 groups, respec- tively. The rate of spectacle independence was significantly higher in the XY1-EM and DIB00V groups (p<0.001), but no significant differences were noted between these two enhanced mono- focal groups (p=0.721). Subjective satisfaction was also assessed in patients who underwent bilateral implantation with XY1-EM or DIB00V. continued from page 19 Comparative evaluation of clinical results and patient- reported outcomes of enhanced monofocal and conventional monofocal intraocular lenses Kabura R, et al. J Cataract Refract Surg. 2025;51:520–524. n 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). n Setting: Kamiamakusa General Hospital, Kumamoto, Japan. n 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. n 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 (XY-1). 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 –1.5 D 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. n 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. continued on page 21
