Intermediate Visual Performance of Clareon Versus Eyhance Enhanced Monofocal Intraocular Lenses.

Background/

Objectives

Intermediate vision has become increasingly important after cataract surgery because many daily activities require functional visual performance beyond distance vision alone. Enhanced monofocal intraocular lenses may improve intermediate visual function while maintaining good distance visual acuity. The aim of this study was to compare binocular distance and intermediate visual outcomes after bilateral implantation of Clareon and TECNIS Eyhance intraocular lenses.

Methods

This was a single-center, non-randomized comparative observational study with assessment of postoperative visual outcomes. Eighty-six patients who had previously undergone uncomplicated bilateral age-related cataract surgery with implantation of the same IOL model in both eyes were included. Forty-two patients received Clareon IOLs and forty-four patients received TECNIS Eyhance IOLs. Postoperative assessment was performed at least 12 weeks after surgery of the second eye. Binocular corrected distance visual acuity (CDVA) and distance-corrected intermediate visual acuity (DCIVA) were measured using ETDRS charts at 4 m and 66 cm.

Results

Baseline biometric and clinical parameters were comparable between groups. Mean postoperative DCIVA was 0.23 ± 0.09 logMAR in the Clareon group and 0.21 ± 0.08 logMAR in the Eyhance group. The mean between-group difference, calculated as Clareon minus Eyhance, was 0.02 logMAR, with a 95% confidence interval from -0.02 to 0.06 logMAR. Mean binocular CDVA was 0.02 ± 0.02 logMAR in the Clareon group and 0.02 ± 0.03 logMAR in the Eyhance group, with a 95% confidence interval for the between-group difference from -0.01 to 0.01 logMAR. Mean postoperative manifest refraction spherical equivalent was -0.27 ± 0.42 D in the Clareon group and -0.29 ± 0.37 D in the Eyhance group.

Conclusions

Both Clareon and TECNIS Eyhance IOLs provided good binocular distance and intermediate visual acuity after bilateral implantation. Intermediate visual performance after Clareon implantation was comparable to that achieved with TECNIS Eyhance, while distance visual acuity remained similarly high in both groups. These findings suggest that both IOL models may represent useful options for patients undergoing cataract surgery who expect good distance vision and functional intermediate visual performance.
