    Abstract Background: Childhood myopia represents a global concern with increasing prevalence in recent decades. Lifestyle factors significantly impact myopia.
    Aim: To evaluate lifestyle factors in myopic children from a metropolitan area in Europe.
    Methods: This was a descriptive study including myopic subjects aged 4-18 years. Patient demographic and clinical data were collected, including cycloplegic refraction in spherical equivalent refraction (SER) and axial length (AL). In addition, a questionnaire on lifestyle factors was conducted between September 2022 and April 2023.
    Results: A total of 321 myopic children were included, aged 10.72 ± 3.05 years, of whom 51.4% were boys, with SER -2.25 ± 1.9 D and AL 24.54 ± 0.98 mm. The mean age of myopia onset was 7.69 ± 3.05 years. A total of 59.8% had family history of myopia. Those children who had <2 h/day of screen time (on weekdays) presented SER -2 ± 1.91 D, compared to those who had >2 h/day, SER: -2.50 ±1.88 D (
    Conclusions: Screen time and near-work time appear to be lifestyle factors related to myopia.

    Abstract Purpose: To assess photopic and mesopic vision in patients implanted with the Bi-Flex® M 677 MY bifocal intraocular lens (IOL).
    Methods: In this prospective clinical study, 25 patients with cataract in both eyes were subjected to cataract surgery and bilateral implantation of the Bi-Flex® M 677MY (Medicontur, Hungary) IOL. Three months after surgery, high-contrast photopic uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were determined. Intermediate at 65 cm (DCIVA) and near at 40 cm (DCNVA) visual acuity were also measured, both with best distance correction. The CSV-1000 test chart was used to assess contrast sensitivity (CS). Defocus curves were constructed under photopic and mesopic conditions, determining binocular best-corrected visual acuity over the range +1.50 D to -4.00 D in 0.50-D steps. A KR-1W Wavefront Analyzer was used to measure pupil size and aberrometric outcomes. Presence and type of dysphotopsia were evaluated with the Likert scale.
    Results: Mesopic mean pupil diameter was 4.58 ± 0.73 mm. The mean values at 3 months were UDVA 0.03 ± 0.09, CDVA -0.05 ± 0.06, DCIVA 0.20 ± 0.07, and DCNVA 0.11 ± 0.08. Mean CS for the 4 frequencies examined were 1.66 ± 0.16, 1.75 ± 0.14, 1.39 ± 0.22, and 0.96 ± 0.19. Significant differences were observed in defocus curves for photopic and mesopic conditions. A significant correlation between pupil diameter and the dysphotopic photopic was found (r = 0.62; p = 0.02).
    Conclusions: The evaluated progressive apodized diffractive design IOL provides effective restoration of visual function in far and near vision distance with an adequate intermediate visual quality between -1.00 and -1.50 focus.

    Abstract Aims: To determine the changes produced on the peripapillary retinal nerve fiber layer (RNFL) thickness, measured by an spectral-domain optical coherence tomography (OCT), after the implantation of a trifocal diffractive intraocular lens (IOL) and compare them with the variations produced by a monofocal IOL implantation.
    Methods: A prospective, double masked study in which 50 eyes belonging to 50 patients with bilateral cataract were enrolled. Sequentially, the first 25 patients were bilaterally implanted with the trifocal diffractive IOL AT LISA® Tri 839 MP and the following 25 patients with the monofocal IOL CT ASPHINA® 409 M/MP. RNFL thickness measurements were performed by Cirrus HD®-OCT before and six months after the second eye surgery.
    Results: Mean patient age was 69.5 ± 6.1 years. In response to surgery, the average RNFL thickness increased 7.29 ± 10.51 µm at the AT LISA® Tri group and 1.96 ± 2.90 µm at the monofocal IOL group from the baseline (p = 0.017). Statistically significant differences in thickness variations were also detected in the superior sector (7.86 ± 7.70 µm at the AT LISA® Tri group vs 1.73 ± 5.74 µm at the monofocal group). Statistically significant differences between the pre and the postsurgery measurements were found in all sectors except the inferior one with the trifocal IOL and in two of the studied sectors (average and temporal) with the monofocal IOL.
    Conclusions: The IOL implantation produce changes in the RNFL thickness, which are larger in case of a trifocal diffractive IOL.

    Abstract Purpose: To establish the changes produced after implantation of a trifocal intraocular lens (IOL) on retinal nerve fiber layer measurements performed with Fourier-domain optical coherence tomography (OCT).
    Methods: This prospective study included 100 eyes of 50 patients with bilateral cataract in surgical range, no other associated ocular involvement, refractive errors between +5 and -5 spherical diopters, and less than 1.5 D of corneal astigmatism. The eyes were operated by phacoemulsification with implantation of 2 different trifocal IOLs (FineVision and AT LISA tri 839MP) in randomized equal groups. Cirrus OCT and Spectralis OCT were performed before surgery and 3 months later. Both analyzed the thickness of the nerve fiber layer and thickness divided by quadrants (6 in case of Spectralis and 4 in case of Cirrus HD).
    Results: The mean age of patients was 67.5 ± 5.8 years. The global nerve fiber layer thickness measured with Spectralis OCT was 96.77 μm before surgery and 99.55 μm after. With Cirrus OCT, the global thickness was 85.29 μm before surgery and 89.77 μm after. Statistically significant differences in global thickness measurements between preimplantation and postimplantation of the IOL were found with both OCT in the 2 groups. Statistically significant differences were also found in temporal and superior quadrants.
    Conclusions: The implantation of a diffractive trifocal IOL alters the results of the optic nerve fiber layer on Fourier-domain OCT in these patients, which should be taken into account in the posterior study of these patients.
