PURPOSE: To compare visual outcomes, contrast sensitivity, optical quality, spectacle independence, and visual disturbances in patients implanted with 2 models of monofocal intraocular lenses (IOLs).
SETTING: Eye Clinic, Department of NEUROFARBA, University of Florence, Italy.
DESIGN: Prospective case series METHODS:: Patients without ocular comorbidities and corneal astigmatism less than 0.75 diopters (D) had cataract surgery with bilateral implantation of either of 2 monofocal IOLs, the Tecnis ZCB00 or the Tecnis Eyhance ICB00 (Johnson & Johnson Vision Care, Inc.). Six months postoperatively, monocular and binocular uncorrected and corrected (at 4 m) distance visual acuities, as well as uncorrected (UIVA), distance corrected, and corrected intermediate (at 66 cm) and near (at 40 cm) visual acuities were measured. Photopic contrast sensitivity, binocular defocus curve, objective scatter index (OSI), Strehl ratio, modulation transfer function (MTF) cutoff, halo and glare perception, and spectacle independence were also evaluated.
RESULTS: A total of 80 eyes of 40 patients were evaluated in this study. Although monocular and binocular uncorrected and corrected distance and near visual acuities were similar between groups, monocular and binocular UIVA were significantly higher in the Eyhance group. There were no statistically significant differences between the 2 groups in terms of photopic contrast sensitivity, OSI, MTF cutoff, Strehl ratio, and glare and halo perception. The ICB00 IOL provided better spectacle independence than the ZCB00 IOL for intermediate distance.
CONCLUSIONS: In patients without ocular comorbidities, the Eyhance ICB00 IOL provided better UIVA and higher intermediate spectacle independence without impairment of far vision and visual quality, compared with the ZCB00 IOL.
