Abstract
Purpose
This study aims to compare the 3-month clinical outcomes between two enhanced monofocal intraocular lenses (IOLs) following cataract surgery.
Setting: Eye Clinic of Careggi University Hospital, Florence, Italy.
Design
Single-center prospective study.
Methods
We included patients with cataract and corneal astigmatism less than 0.75 D, with no ocular comorbidities, who underwent unilateral cataract surgery with implantation of either the Tecnis Eyhance ICB00 (N = 25) or Evolux (N = 25) IOLs. Standard cataract procedures were performed without complications. The main outcome measures included uncorrected and corrected visual acuity at distance (4 m), intermediate (60 cm) and near (40 cm) at 3-month follow-up. Additionally, monocular defocus curves, aberrometric profiles, and perceptions of halo and glare were evaluated.
Results
The study involved 50 patients (26 male, 24 female) with a mean age of 68 ± 8 years. Preoperative characteristics were similar between the groups, and no intraoperative or postoperative complications were reported. Statistically significant differences were observed between the groups, with the Evolux IOL showing superior results (p < 0.05) in terms of uncorrected and corrected visual acuity at near, intermediate, and distance, as well as in aberrometric profiles (lower-order aberration root-mean-square [RMS], higher-order aberration RMS, spherical equivalent RMS, and point spread function) and defocus curves.
Conclusions
Based on our experience, while both IOLs offer substantial visual performance for intermediate and distance vision, the Evolux IOL demonstrated superior mean visual outcomes and objective parameters at the 3-month follow-up compared to the Tecnis Eyhance IOL. This indicates a potential advantage of the Evolux IOL in providing better visual performance.
