Visual Performance and Optical Quality after Implantation of a New Generation Monofocal Intraocular Lens

Abstract

Purpose To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order aspheric optic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platform and material. Methods The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00 or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed. Subjects with ocular comorbidities or corneal astigmatism greater than 1.00 diopters were excluded. The uncorrected near, intermediate, distance visual acuity and corrected distance visual acuity were the main outcome measures. Optical quality parameters measured using an optical quality analysis system, clinical records including age, sex, laterality, ocular dominance, and information related to refractory errors was also collected. Parameters related to the refractory errors were all uniformly based on the Barrett Universal II formula. Results Of the 197 recruited patients, 111 and 86 were implanted with the ICB00 and ZCB00, respectively. No statistically significant differences in baseline parameters were observed between the two groups. While no statistically significant differences in distance visual acuity or optical quality were found between the two groups, compared to the ZCB00 group, the ICB00 group showed significantly higher intermediate visual acuity ( p < 0.001) and near visual acuity ( p < 0.05) 3 months postoperatively. Conclusions ICB00 provided superior intermediate vision and comparable distance performance and photic phenomena compared to a standard monofocal IOL.

Comparison Between an Intraocular Lens With Extended Depth of Focus (Tecnis Symfony ZXR00) and a New Monofocal Intraocular Lens With Enhanced Intermediate Vision (Tecnis Eyhance ICB00)

“… 31 Several studies also reported the excellent distance VA of the ICB00, with no difference from a typical monofocal IOL. 3 , 10 , 13 These results are consistent with the results of the present study. In the current study, the UDVA values were 0.13 ± 0.13 and 0.11 ± 0.10, and the CDVA values were 0.05 ± 0.08 and 0.03 ± 0.05 in the ZXR00 and ICB00 groups, respectively.…”

“…Studies have compared ZXR00 and a standard monofocal IOL, Tecnis ZCB00 (Johnson & Johnson Vision, Santa Ana, CA, US) (ZCB00), as well as ICB00 and ZCB00 have already been reported. 11 – 13 …”

A comparison of clinical outcomes and optical performance between monofocal and new monofocal with enhanced intermediate function intraocular lenses: a case-control study

“…On the other hand, this study was conducted in a retrospective manner in Asia. In line with this study, a previous study conducted in a retrospective manner in Asia showed that the Eyhance ICB00 IOL provided superior intermediate and near vision compared to the ZCB00 IOL [ 23 ]. Therefore, the effect of the Eyhance IOL for improving near vision needs to be confirmed through a large-scale study.…”

Comparative analysis of a presbyopia-correcting intraocular lens that combines extended depth-of-focus and bifocal profiles with a standard monofocal intraocular lens

“…Likewise, within our study, the UDVA values were 0.08 ± 0.06 and 0.06 ± 0.07 and the CDVA values were 0.03 ± 0.05 and 0.03 ± 0.05 in the ZCB00 and ZFR00 groups, respectively. Previous studies have reported monocular UIVAs (at 66 cm) of 0.25 ± 0.18 [30], 0.34 ± 0.12 [29] for the ZCB00 and 0.05 ± 0.03 [8], 0.04 ± 0.09 [6] for the ZFR00, monocular UNVA (at 40 cm) of 0.48 ± 0.32 [31], 0.51 ± 0.19 [29] for the ZCB00 and 0.03 ± 0.05 [8], 0.05 ± 0.13 [6] for the ZFR00. In the current study, the monocular UIVA (at 66 cm) values were 0.33 ± 0.12 for the ZCB00 and 0.02 ± 0.05 for the ZFR00 and the monocular UNVA (at 40 cm) values were 0.48 ± 0.15 for the ZCB00 and 0.03 ± 0.06 for the ZFR00.…”

“…A previous clinical study reported results consistent with those from this study. Earlier studies reported monocular UDVAs of 0.07 ± 0.09 [21] and 0.10 ± 0.14 [29] for the ZCB00 and 0.04 ± 0.10 [9] and − 0.01 ± 0.04 [8] for the ZFR00. Earlier studies reported monocular CDVA of − 0.02 ± 0.09 [21] and 0.03 ± 0.06 [29] for the ZCB00 and − 0.02 ± 0.07 and − 0.04 ± 0.02 [10] for the ZFR00.…”
