Purpose

Tecnis Eyhance is a non-diffractive continuous power monofocal intraocular lens (IOL) that provides both improved distance and intermediate vision correction. The goal of this study is to evaluate clinical outcomes and subjective visual function following implantation of a Tecnis Eyehance IOL in blended vision for patients with presbyopia.

Setting

Herzig Eye Institute and the University of Ottawa Eye Institute in Ottawa, Ontario, Canada.

Methods

This is a retrospective-prospective, non-randomized, multi-center study of patients undergoing cataract or refractive lens exchange with implantation of the Tecnis Eyhance IOL between August 2020 and December 2022. The procedure aimed for blended vision with a target of emmetropia in the dominant eye and a target of myopia ranging from -0.50 to -1.25D in the non-dominant eye. Key outcomes assessed included 3-month postoperative uncorrected visual acuities at distance, intermediate and near, defocus curves, spectacle independence, and visual function as evaluated by the NEI-VFQ questionnaire.

Results

Forty-four participants (88 eyes) were evaluated. Mean binocular uncorrected distance, intermediate and near visual acuities at 3 months were -0.05, 0.10, and 0.28 logMAR, respectively. The frequency of participants who were spectacle-free for distance, intermediate, and near activities was 80%, 64%, and 34%, respectively. The average subjective visual function score for those who completed the NEI-VFQ questionnaire was 74.6/100 preoperatively and 91.3/100 at 3-months postop.

Conclusion

The Tecnis Eyhance continuous power IOL provides excellent distance and intermediate vision (≤0.1 logMAR) and acceptable near vision (<0.3 logMAR) when implanted targeting blended vision. Furthermore, it improves quality of life and allows spectacle independence for most distance and intermediate activities.
