Real World Outcomes Of Bilateral Implantation Of The Tecnis Eyhance Advanced Monofocal Iol

Cataract surgery is the most commonly performed surgery in the world, and the demand for precise refractive outcomes is increasing. Standard monofocal intraocular lens (IOL) implantation may result in dissatisfaction due to compromised intermediate and near vision. The Tecnis Eyhance® advanced monofocal IOL promises better intermediate vision due to a continuous, central increase of dioptric power, while delivering comparable image quality to standard monofocal lenses. In this report we aim to analyse the real world outcomes of bilateral implantation of the Tecnis Eyhance® IOL.

Prospective non-controlled study of healthy patients who underwent cataract surgery with TECNIS Eyhance® IOL implantation. Exclusion criteria were corneal astigmatism >1D, high myopia (refractive error > -6D or axial length of > 26.5mm) or concomitant ocular pathology. IOL power calculations were performed with the SRK/T formula, with the dominant eye targeted to emmetropia and the non-dominant eye to -0.50D. Post operative evaluation (6 weeks after surgery) included monocular and binocular uncorrected distance, intermediate and near visual acuities (UDVA, UIVA, UNVA), best corrected visual acuity (BCVA) and distance corrected intermediate and near visual acuity (DCIVA, DCNVA). Visual symptoms were assessed with the PRVSQv2 questionnaire. 

Forty-two patients – 29 female - with a mean age of 72.4±5.8 (60-84) years were included in the study.  Preoperative BCVA, in logMAR, was 0.32±0.22. Mean post-operative binocular UDVA, UIVA and UNVA was 0.01±0.05, 0.06±0.07 and 0.25±0.09, with respective BCVA, DCIVA and DCNVA of -0.03±0.04, 0.1±0.05 and 0.3±0.06; 97.6% of patients reached a binocular UDVA of 0.1 and 81% achieved the same oucome for UIVA. No included variable correlated with the intermediate and near visual outcomes. Nearly all patients (39/42 - 93%) denied positive dysphotopsias such as halos and glare.  

Our study demonstrates that primary implantation of the advanced monofocal Tecnis Eyhance® IOL with a mini-monovision protocol yields favorable outcomes in terms of intermediate and near visual acuity, while maintaining excellent distance visual acuity, with minimal optical side effects typically associated with extended depth of focus or multifocal IOLs. These findings suggest that the Tecnis Eyhance® IOL presents a safe and effective refractive option for cataract surgery patients seeking enhanced intermediate and near visual outcomes, and holds promise for widespread implementation in clinical practice.
