Summary: The study aimed to investigate the effectiveness of orthokeratology (ortho-k) lenses for myopia control and the corneal changes with increased compression factor. The findings showed that ortho-k lenses with increased compression factor can effectively slow down the progression of myopia without compromising corneal health. Further research is needed to confirm the potential mechanism of an increased compression factor for improved myopia control effectiveness.

Summary: Surveys in 2015 and 2019 showed that there was a high level of concern and activity about myopia among eye care practitioners, but most of them still prescribed single vision interventions for young myopes. This research aimed to provide updated information on this topic. The results showed that practitioners in Asia had a significantly higher level of concern about pediatric myopia compared to other continents. Combination therapy was perceived as the most effective method of myopia control, followed by orthokeratology and pharmaceutical approaches, while single vision interventions were seen as the least effective.

Summary: This study aimed to investigate the effect of 0.01% atropine on ocular axial elongation in myopic children. The meta-analysis found that the combination of orthokeratology and 0.01% atropine can effectively control myopia progression, providing helpful evidence for its effectiveness.

Summary: The study found that increasing the compression factor did not result in significant differences in subjective refraction, visual acuity, unaided vision, or the total ocular HOA profile in myopic adults after long-term ortho-k lens wear.

Summary: This study compared the efficacy and safety of corneal refractive therapy (CRT) lenses and vision shaping treatment (VST) lenses for myopia control in children. The results showed that compared with VST lenses, CRT lenses had a weaker effect on myopia control but were safer. Different types of VST lenses had similar efficacy and safety in controlling myopia progression.

Summary: The AAO established the Task Force on Myopia in 2019 to address the global increase in myopia prevalence and its associated complications. Led by recognized experts from various fields, the Task Force aims to formulate an action plan to improve the issue from different perspectives.

Summary: The Montreal Experience suggests that personalized MCS may effectively manage myopia. When using customized or smaller treatment zone orthokeratology lens design, it shows axial length evolution comparable to the documented natural evolution of emmetropes. Future research on other populations will confirm this trend.

Summary: This study retrospectively investigated the axial length changes in myopic children wearing orthokeratology lenses and found that after initial shortening, the axial length rapidly rebounded during the washout period and shortened again when lenses were re-worn. The changes in axial length were significantly correlated with the initial axial length. Therefore, measuring axial length after the washout period can provide a more objective and accurate evaluation of orthokeratology, and the existence and degree of axial shortening can predict long-term myopia development.

Summary: This study compared the efficacy of atropine, Ortho-K, and combined atropine with Ortho-K for childhood myopia through a network meta-analysis. The results showed that different dosages of atropine and combined treatment could effectively slow down myopic progression, and the efficacy of atropine was dose-related. Additionally, Ortho-K and low-dose atropine had similar efficacy, and the combination of 0.01% atropine with Ortho-K had comparable efficacy to high-dose atropine.

Summary: The purpose of this study was to investigate the relationship between patients' baseline biometric factors or lens parameters and the diameter of the treatment zone in young myopic children undergoing Corneal Refractive Therapy. Retrospective review of data from patients undergoing Corneal Refractive Therapy lens treatment within two years was conducted. Results showed that spherical refraction, flat keratometric reading, Reverse Zone Depth 2, Landing Zone Angle 1, and lens diameter were independent factors of treatment zone diameter. Logistic regression analysis accurately predicted the treatment zone size with a 71.5% accuracy.

Summary: The study explored the one-month change in subfoveal choroidal thickness (SFChT) of myopic children treated with 0.01% atropine, orthokeratology (OK), or their combination. Results showed a significant increase in SFChT in the ACO, OK, and atropine groups, while it decreased in the control group. The combination of orthokeratology and atropine led to a greater increase in SFChT compared to monotherapy with atropine, suggesting a potentially more effective treatment for childhood myopia control.

Summary: Orthokeratology is a method of temporarily reshaping the cornea using specialty contact lenses to correct refractive errors, and has been increasingly used to slow the progression of myopia in children. This report reviews the practice of ortho-k, including safety considerations, suitable candidates, and key factors such as lens design.

Summary: This study aimed to compare the effects of toric orthokeratology (TOK) and soft toric multifocal (STM) contact lenses on peripheral refraction in patients with astigmatism and myopia. The results showed that TOK induced greater myopic shift and astigmatism compared to STM, which may impact the efficacy of myopia management.
