“…Kang et al reported that Tecnis Eyhance can not only achieve superior intermediate vision and comparable visual performance at distance, but also generate low incidence of photic phenomena comparable to that of a Tecnis standard monofocal IOL [9]. Similar results were observed in other studies that compared the Tecnis Eyhance with Alcon and Rayner's standard monofocal IOLs [11,12].…”

Background: To compare the clinical outcomes of bilateral implantation of enhanced intermediate function intraocular lenses (IOLs) and standard monofocal IOLs. Methods: In this prospective, randomized, comparative controlled study, we compared the visual outcomes of patients who underwent bilateral cataract surgery at the Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, with either enhanced monofocal IOLs (Tecnis Eyhance, ICB00, Johnson and Johnson Vision Care, Inc) (Group 1) or standard monofocal IOLs (Tecnis, ZCB00, Johnson and Johnson Vision Care, Inc) (Group 2). The assessment included monocular and binocular uncorrected distance visual acuity (UDVA), uncorrected intermediate (UIVA at 60 cm) and near (UNVA at 40 cm) visual acuity, uncorrected defocus curves, contrast sensitivity testing (CST), and reading speed test using Quality of vision was evaluated using the Visual Function Questionnaire (VFQ-25). Results: At 3-months postoperatively, monocular and binocular outcomes of UIVA and UNVA were statistically significantly better in Group 1 (P<0.05). The binocular uncorrected defocus curve of Group 1 showed statistically significantly better outcomes at vergence ranges of -1.5 to -4.0 D (P<0.05). Significantly higher reading speed test was also observed in Group 1 in all ranges tested (1.0 to 0.1 LogMAR) (P<0.05). There were no statistically significant differences in CST between groups. Conclusions: Bilateral implantation of enhanced monofocal IOLs provided better vision at intermediate and near distances compared to standard monofocal IOLs, while maintaining good distance vision and contrast sensitivity.

Positioning of enhanced monofocal intraocular lenses between conventional monofocal and extended depth of focus lenses: a scoping review

et al. 2023

Background New intraocular lenses (IOLs) have emerged since the originally coined monofocal and multifocal IOLs. The extended depth of focus (EDoF) and enhanced monofocal IOLs (mono-EDoF) that have appeared in the last decade have caused some confusion in their classification. The aim of this review was to summarize the outcomes provided by mono-EDOF IOLs and to determine which of the endpoints, described by the American National Standard (ANSI) for EDoF IOLs, are fulfilled. Methods The MEDLINE, EMBASE, and WEB OF SCIENCE databases were searched. Two independent reviewers screened the studies for inclusion and data extraction. The search strategy was limited to studies published between 2020 and 2022, but not by language. The results are presented as a narrative summary accompanied by tables, in alignment with the objectives of this scoping review. Compliance with the endpoints for clinical outcomes described in the American National Standard Z80.35–2018 (ANSI) for EDoF lenses was checked and additional endpoints were defined. Results Two systematic reviews, 13 laboratory, 21 clinical, and two mixed studies were included. Tecnis Eyhance was the mono-EDOF with the highest volume of evidence to date. Although laboratory studies included other IOLs, clinical evidence for them is still scarce, with only one study of IsoPure compared to a standard monofocal IOL. Evidence in comparison to EDoF lenses is also scarce, even for Tecnis Eyhance, with only three studies including this lens in comparison to an EDoF lens. After evaluation of the ANSI criteria, agreement was found in the failure for the increase in depth of field equal to or greater than 0.5 D for a visual acuity (VA) level of 0.2 logMAR and none of the studies supported that the median monocular VA at intermediate distance was at least 0.2 logMAR. Conclusions Additional clinical evidence is required for other mono-EDOF IOLs beyond Tecnis Eyhance. Until the arrival of a standard classification, mono-EDOF should be better still classified as monofocal because the ANSI standards were not fully met.

“…De Luis Eguileor et al found a significant correlation between SA and intermediate VA; this endorses that with SA of intermediate values, the Eyhance IOL offers better intermediate VA. 9 On the other hand, Nanavaty et al found a clinically non-significant difference in total and internal SA with the TECNIS Eyhance IOL, indicating that the Eyhance IOL does not induce SA. 18 The Eyhance can be offered to patients undergoing routine cataract surgery. It is a great choice when premium IOLs are not desired.…”

To evaluate postoperative visual performance and total ocular aberration in cataract patients after implantation of the TECNIS Eyhance™ intraocular lens (IOL). Methods: Our study is a prospective interventional non-comparative study that was conducted on 34 eyes of 17 patients who underwent phacoemulsification and Eyhance IOL implantation. Postoperative corrected and uncorrected near and far visual acuity and total ocular aberration were assessed 3 months after surgery. Results: Our study included 34 eyes of 17 patients. At the third postoperative month, the mean spherical equivalent (SE) was −0.32 diopters (D) (SD ±0.62), and the mean distance-corrected near visual acuity (DCNVA) was 0.33 (SD ±0.15) and 0.42 (SD ±0.17) decimal notation (DN) monocular and binocular, respectively. The mean near distance with maximum visual acuity was 79.47 cm (SD ±7.70) and 74.76 cm (SD ±7.90) monocular and binocular, respectively. The mean postoperative minimum reading addition (add) was 1.6 D (SD ±0.47). The mean spherical aberration (SA) was 0.13 µm (SD ±0.09). The correlation of amount of spherical aberration with power of minimum reading add at 40 cm was not statistically significant (p=0.324). Conclusion:The TECNIS Eyhance IOL provides good intermediate visual acuity and decreases the power of the reading add needed after phacoemulsification.
