“…In this refractive technology, continuous changes of power in the optic zone are created with higher-order asphericity. The higher-order aspheric monofocal IOLs are intended to provide improved intermediate vision [ 20 ]. They are visually indistinguishable from the same platform-standard monofocal lOLs.…”

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.

“…Previous studies reported the Eyhance ICB00 IOL’s effectiveness as it provided improved intermediate vision compared to the monofocal 1-piece IOL [ 10 , 21 , 22 ]. In those previous studies, the Eyhance ICB00 IOL yielded better UIVA, higher spectacle independence at intermediate distance, and similar optical quality compared to the classic monofocal IOL, but provided similar distance and near visual acuities [ 10 , 21 , 22 ]. The results of this study also showed that the Eyhance ICB00 IOL produced better intermediate VA and similar optical quality compared to the ZCB00 IOL.…”

Background To compare clinical outcomes and optical performance of a new monofocal with enhanced intermediate function intraocular lenses (IOLs) with that of conventional monofocal IOLs. Methods Sixty eyes of 30 patients who underwent phacoemulsification with bilateral implantation of the ICB00 (15 patients) or ZCB00 (15 patients) IOLs were enrolled. Binocular corrected distance visual acuity (CDVA), distance corrected near visual acuity (DCNVA), and distance corrected intermediate visual acuity (DCIVA) were measured at 4 weeks after surgery. Patient satisfaction for overall, near, intermediate, and distance vision were assessed. The binocular defocus curves were measured. The root mean square of modulation transfer function (MTFRMS) was measured in the optical bench study. Results The mean binocular DCIVA was significantly better in the ICB00 group (0.01 logMAR) compared to the ZCB00 group (0.13 logMAR), but CDVA and DCNVA were not. The patient satisfaction for near and intermediate vision was significantly higher in the ICB00 group compared to the ZCB00. However, there was no difference in patient satisfaction for overall and distance vision between two groups. The defocus curves showed that mean visual acuity of the ICB00 group was significantly better than that of the ZCB00 group at between − 1.00 D to − 3.00 D of defocus. The ICB00 IOL had higher MTFRMS values at between − 0.50 D to − 2.00 D of defocus compared to the ZCB00 IOL. Conclusions The ICB00 IOL provides better binocular intermediate vision and higher satisfaction for near and intermediate vision than the ZCB00 IOL while maintaining excellent distance vision.

“…Thus, this postoperative complaint is typically associated with multifocal IOLs rather than monofocal ones [15,16]. Recent clinical and laboratory studies demonstrated a comparable amount of dysphotopsia with the ICB00 and the control monofocal Tecnis IOL [2][3][4][5], which may be used as a reference to test the susceptibility of new mono-EDoF designs to produce such phenomena.…”

Introduction: This study aims to compare preclinical visual-quality metrics and halo size of intraocular lenses (IOL) with enhanced intermediate vision to a standard monofocal lens. Methods: Three monofocal-IOL models with an extended-depth-of-focus (EDoF) intended for monocular implantation (Tecnis ICB00, AE2UV/ZOE, and IsoPure) and one for monovision (RayOne EMV) were compared against a standard monofocal lens (Tecnis ZCB00). An optical-metrology station was used in the assessment of IOLs' optical quality in polychromatic light. The imaging quality was compared with metrics derived from the optical transfer function. Halo size was estimated from the projection of the point spread function under scotopic pupil. Results: The monofocal IOL showed the highest image quality at the far focus. The ICB00's, the AE2UV/ZOE's, and the IsoPure's performance at -1D was superior to that of the monofocal lens. The monocular defocus tolerance of the RayOne EMV was comparable with that of the ZCB00. The RayOne EMV's intermediate range was improved in a monovision configuration (-1D offset). This approach, however, yielded the largest halo area, i.e., 53% of the ZCB00's halo, compared to 34% for the IsoPure, 14% for the AE2UV/ZOE, and 8% for the ICB00. Conclusion:The mono-EDoF models have a clear advantage over the standard monofocal lens by expanded imaging capability beyond -0.5D. Although the RayOne EMV provided the largest (binocular) visual-range extension, it was at the expense of monocular vision and higher susceptibility to halo. The ICB00's and the AE2UV/ZOE's halo-profile was similar to that of the ZCB00, indicating their low potential to induce photic phenomena.
