Significance: The myopia control effect of orthokeratology accrues over time, with 11 years of lens wear providing a cumulative absolute reduction in axial elongation of -0.69 mm in comparison with spectacle lens wear. Steeper corneas are likely to benefit from enhanced myopia control efficacy.

Aims: To evaluate the efficacy of CARE spectacle lenses in slowing myopia progression among European children.

Methods: In a 2-year randomised, parallel-group, double-masked, multicentre clinical trial, 234 European children aged 6-13 years were enrolled. All participants were myopic, with a cycloplegic spherical equivalent refractive error (SE) between -0.

Background: Surveys conducted between 2015 and 2022 showed growing concern among European eye care practitioners about myopia management, though adoption of effective strategies varied. This study updates findings from 2024, analysing trends in attitudes and strategies for myopia management across Europe from 2015 to 2024.

Methods: A cross-sectional online survey targeting European eye care practitioners was distributed in multiple languages through professional bodies.

This meta-analysis investigates the effectiveness of outdoor activities in reducing the onset of myopia in children and adolescents by analysing changes in axial elongation and spherical equivalent refractive error. Following PRISMA guidelines and registered in PROSPERO (CRD42024592971), the study included randomized controlled trials (RCTs) and observational studies. The eligibility criteria targeted children and adolescents aged 6 to 18 years with varying levels of outdoor exposure.

: Asymmetric myopic peripheral defocus lenses (MPDLs) have proven to be effective in slowing the progression of myopia in Spanish children over a period of 12 months. The purpose of this study was to assess the MPDL spectacles' efficacy in slowing myopia progression over a 24-month period in children. : This study extends the follow-up period of the double-masked, prospective, and randomized clinical trial previously published to 24 months.

Purpose: To evaluate the safety of orthokeratology contact lens wear in slowing the axial elongation of the eye in myopic children.

Methods: Safety data from three prospective studies, which evaluated the use of orthokeratology for slowing myopia progression in children in comparison to a parallel control group of single-vision spectacle lens wearers over a 2-year period, were pooled together for analysis. The primary and secondary safety endpoints are the comparisons of adverse events and slit-lamp findings grades ≥ 2 between orthokeratology and control groups, respectively.

Purpose: To evaluate the efficacy of orthokeratology contact lens wear in slowing the axial elongation of the eye in myopic children.

Methods: Data from three prospective studies, which evaluated the use of orthokeratology for slowing myopia progression in children in comparison to a parallel control group of distance, single-vision spectacle lens wearers over a 2-year period, were pooled together for analysis.

Results: Collectively, data from 125 orthokeratology and 118 control subjects were analyzed in this study.

Background: Different designs of ophthalmic lenses have been studied to control the progression of myopia in children. This study aims to evaluate the short-term efficacy of a new design of ophthalmic lens with asymmetric myopic peripheral defocus (MPDL) on myopia progression in children compared to a control group wearing a single-vision lens (SVL).

Methods: Children aged 5 to 12 with myopia up to -0.

Background: There are environmental factors that may contribute to the onset of myopia. This study aims to evaluate the children's lifestyle changes before and after the COVID-19 lockdown and how they can influence their vision.

Methods: The same questionnaire was administered to children aged between 5 and 7 in Spain every year in September before (2017-2019) and after the COVID-19 lockdown (2020-2021).

Objective: The high incidence of keratoconus has caused its management, etiology, and pathogenesis to be controversial topics in the ophthalmology field. This study aims to analyze the relationship between the different publications and authors through citation networks, as well as to identify the research areas and determine the most cited article.

Methods: The search for publications was carried out through the Web of Science database, using the term "Keratoconus" between 1900 and December 2022.

Objective: This study analyses strategies and attitudes on myopia management reported by eye care practitioners (ECP) from Spain in 2022.

Methods: A questionnaire was distributed to ECPs worldwide via the internet through professional associations. The questionnaire was distributed by email to all registered Spanish optician-optometrists.

Background: Myopia prevalence has been increasing in the last decades, and its pathological consequences, including myopic maculopathy and high myopia-associated optic neuropathy, are now one of the most common causes of visual impairment. It is estimated that by 2050, more than 50% of Europeans and Americans will be myopes, which is alarming due to the high morbidity of myopes over - 6.00D.

Introduction: It is well known that the femtosecond laser lamellar cut induces some degree of surface roughness. Nevertheless, as in femtosecond laser-assisted LASIK (FS-LASIK), an excimer LASIK ablation is performed, and the post-ablation stromal bed should show some degree of smoothening. We decided to compare, using atomic force microscopy (AFM), the roughness of the corneal stromal bed, after a femtosecond lasers device flap was created with or without an excimer myopic ablation.

Significance: Scleral lenses rely on the scleroconjunctival region without bearing the cornea, which could improve the symptoms and modify the corneal nerve plexus morphology.

Purpose: This study aimed to evaluate symptoms and changes in corneal nerve plexus morphology and density of Langerhans cells in keratoconus patients with and without intrastromal corneal ring before and after scleral lens wear.

Methods: Sixteen scleral lens wearers with keratoconus were recruited for this short-term experimental pilot study.
