Abstract

Purpose: To compare the visual performance, spectacle independence, and subjective visual quality of 2 enhanced monofocal intraocular lenses (IOLs): Eyhance ICB00 and ZOE Primus-HD.

Setting: Ophthalmology Department, San Raffaele Scientific Institute, Milan, Italy.

Design: Prospective case series.

Methods: Patients without ocular comorbidities and corneal astigmatism <0.75 diopters (D) undergoing cataract surgery with bilateral implantation of enhanced monofocal Eyhance and ZOE were included. 6 months postoperatively, the following parameters were analyzed: subjective and objective refraction; monocular and binocular corrected (4 m) and uncorrected (UDVA) distance visual acuities; corrected distance, intermediate (66 cm), and near (40 cm) visual acuities, as well as uncorrected intermediate (UIVA) and uncorrected near (UNVA) visual acuities; photopic contrast sensitivity; binocular defocus curve; halo and glare perception; and spectacle independence.

Results: 100 eyes of 50 patients were evaluated (25 patients per IOL group). The 2 IOLs showed superimposable visual performances, without significant differences in terms of refractive and visual outcomes, defocus curves, contrast sensitivity, scores of vision quality, and spectacle independence. Of note, monocular and binocular UDVA was excellent in both groups. The 2 IOL models achieved satisfactory binocular UIVA, with more than 70% of patients reaching a binocular UIVA of ≤0.1 logMAR. Up to 84% of patients eventually declared to feel comfortable frequently while staying at intermediate distance.

Conclusions: The general visual outcome of the Eyhance ICB00 and the ZOE Primus-HD enhanced monofocal IOLs is similar, with special reference to the satisfactory spectacle independence for intermediate distance.
