RESUMEN

Purpose: To compare the outcomes of the Tecnis Eyhance ICB00 IOL, designed to enhance intermediate vision, to a conventional Tecnis Monofocal ZCB00 IOL. Methods: This retrospective analysis compared two cohorts of patients undergoing lens replacement surgery with bilateral implantation of the Tecnis ICB00 or the Tecnis ZCB00 IOL (383 patients in each group). Monocular and binocular uncorrected distance (UDVA), intermediate (UIVA; 66cm), and near (UNVA; 40cm) visual acuities, refractive predictability, and patient-reported outcomes were compared. A sub-analysis of patients with the Eyhance IOL was performed to compare patients who achieved bilateral emmetropia to those with mini-monovision. One-month postoperative outcomes were analyzed. Results: Both groups had comparable UDVA outcomes. On average, both monocular and binocular UIVAs were approximately one Snellen line better in patients implanted with Eyhance IOL (monocular UIVA: ICB00 0.23 ± 0.18 logMAR, ZCB00 0.33 ± 0.19 logMAR; binocular UIVA: ICB00 0.18 ± 0.18 logMAR, ZCB00 0.26 ± 0.20 logMAR, p < 0.01). Likewise, the mean UNVA was also one Snellen line better with the ICB00 model (monocular UNVA: ICB00 0.51 ± 0.20 logMAR, ZCB00 0.61 ± 0.18 logMAR; binocular UNVA: ICB00 0.42 ± 0.19 logMAR, ZCB00 0.51 ± 0.22 logMAR, p < 0.01). There was no difference between the two groups in overall satisfaction or visual phenomena. A subgroup of patients who achieved mini-monovision with Eyhance IOL had, on average, one Snellen line better UIVA and UNVA compared to patients with bilateral emmetropia. Conclusion: Patients receiving the enhanced monofocal IOL had better intermediate and near vision compared to those receiving the conventional monofocal IOL, with similar levels of patient-reported photic phenomena in both groups.

RESUMEN

PURPOSE: To evaluate and compare the visual outcomes of an enhanced monofocal intraocular lens (IOL) with two different monofocal IOLs. SETTING: Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy. DESIGN: Prospective, single-center, single-masked, randomized controlled clinical study. METHODS: The study included patients undergoing phacoemulsification and IOL implantation. Patients were consecutively randomized by block randomization and assigned in a 1:1:1 allocation ratio to three study arms to bilaterally receive Tecnis Eyhance™ (model ICB00) or Tecnis® monofocal 1-piece (model PCB00) or Clareon® monofocal (model CNA0T0), respectively. Monocular and binocular (both corrected and uncorrected) visual acuities for far, intermediate and near were registered and compared among groups at 3 months. To track changes in patient quality of life, the Catquest-9SF questionnaire was administered to each patient before and after cataract extraction. RESULTS: Ninety patients (30 for each group) were enrolled. At 3 months follow-up, statistically significant differences for intermediate visual acuities were found between the three groups. Nonstatistically significant differences were observed for distance visual acuities and the changes in Catquest-9SF scores. CONCLUSION: Tecnis Eyhance™ provided better results in intermediate visual outcomes without adverse effects on patients' quality of life.

RESUMEN

The purpose of this study was to compare the visual performance and optical quality between three new enhanced monofocal intraocular lenses (IOLs). This retrospective study included patients affected by cataracts with corneal astigmatism less than 0.75 D and no ocular comorbidities who underwent cataract surgery with bilateral implantation of Tecnis Eyhance ICB00 (Johnson & Johnson Vision Care, Inc., Jacksonville, FL, USA), Vivinex Impress XY1-EM (Hoya Surgical Optics, Singapore) or IsoPure 123 (PhysIOL, Liege, Belgium) IOLs. Three months postoperatively, monocular and binocular uncorrected and corrected distant, and intermediate and near visual acuities were measured. Binocular defocus curve, photopic contrast sensitivity, Point Spread Function (PSF), low order aberrations (LOAs), high order aberrations (HOAs), objective scatter index (OSI), halo and glare perception were also evaluated. This study included a total of 72 eyes from 36 patients. Visual acuity outcomes, PSF, LOAs, HOAs and OSI were similar between groups. There were no statistically significant differences in terms of photopic contrast sensitivity, halo or glare perception. In patients without ocular comorbidities, the Eyhance ICB00 IOL, the Vivinex Impress IOL and the Isopure IOL-even though based on different optical properties-provided similar results in terms of visual acuity, contrast sensitivity and intraocular aberrations, with no influence on photic phenomena.
