Purpose: A novel enhanced monofocal intraocular lens (IOL) has been developed to improve functional intermediate vision, maintaining a distance vision comparable to a standard monofocal lens and avoiding the drawbacks of multifocal IOLs. The aim of this study is to perform optical bench analysis and to evaluate refractive and visual outcomes and patient satisfaction. Methods: This prospective comparative single-center study was conducted in Careggi Hospital, University of Florence (Italy). We included 100 eyes from 50 patients who underwent bilateral cataract surgery. One group received the standard monofocal Tecnis GCB00 IOL, while the other group received the novel enhanced monofocal Evolux IOL. We evaluated binocular visual and refractive outcomes at 6 months after surgery. Binocular defocus curves and contrast sensitivity (CS) were also assessed. Optical quality was also analyzed in terms of higher-order aberrations (HOAs), modulation transfer function (MTF), objective scatter index (OSI), Strehl ratio, effective lens position (ELP), and halo analysis. A Patient-Reported Spectacle Independence Questionnaire (PRSIQ) was performed to assess spectacle independence outcomes. Finally, we analyzed the optical bench of both lenses. Results: All eyes implanted with Evolux achieved excellent distance vision, comparable to that achieved with GCB00. Evolux showed better intermediate and near vision, without any loss of visual quality, contrast sensitivity, or the presence of halos and photic phenomena. The optical bench analysis confirmed the different optical properties of the two lenses and supported the behavior obtained with the clinical defocus curve. Conclusions: These preliminary results show good refractive accuracy and visual outcomes for the enhanced monofocal IOL Evolux after cataract surgery. Further studies are needed to confirm our findings in terms of the number of patients and the period of follow-up.

Background/Objectives: During cataract surgery, topical anesthesia is routinely achieved through the instillation of topical anesthetic eye drops, while different agents may be applied to the corneal surface during the procedure to support lubrication and protection. The impact of these intraoperative strategies on corneal integrity and postoperative ocular surface recovery remains an area of clinical interest. This study aimed to compare the intraoperative and postoperative effects of applying a topical anesthetic gel (Ophtesic, Horus Pharma) on the corneal surface versus the use of balanced salt solution (BSS) during cataract surgery. Methods: In this longitudinal, observational prospective study, 24 eyes of 24 patients undergoing phacoemulsification received either topical anesthetic gel (n = 15) or BSS irrigation (n = 9). Central corneal thickness (CCT) and epithelial thickness were measured preoperatively and on postoperative days 1, 5, and 15 using anterior segment optical coherence tomography (AS-OCT). Basal epithelial cell (BEC) density was assessed by in vivo confocal microscopy (IVCM), while OSDI score, non-invasive breakup time (NI-BUT), and Schirmer test I values were evaluated preoperatively and on postoperative days 5 and 15. Patient and surgeon satisfaction were rated using a Likert-like scale. Results: Both groups showed increased CCT and epithelial thickness at day 1. In the gel group, CCT returned to baseline by day 15 (p = 0.361), and epithelial thickness normalized by day 5 (p = 0.066). In the BSS group, CCT remained elevated at day 15 (p < 0.05), and epithelial thickness decreased at day 5 (p < 0.05) before returning to baseline. BEC density normalized at day 15 in the gel group (p = 0.107) but remained altered in the BSS group (p < 0.05). NI-BUT Schirmer I, and OSDI showed a trend toward faster recovery in the gel group than in the BSS group. Conclusions: In this exploratory study, intraoperative application of a topical anesthetic gel appeared to support early normalization of corneal and tear film parameters while providing effective anesthesia. Further studies are warranted to confirm these observations and evaluate potential long-term benefits.
