Summary

The prevalence of myopia and its complications has risen considerably in recent decades, particularly among children and teenagers. This trend is also spreading in Europe, driven by the increase in screen time and the intensive use of new technologies and social media, particularly among the younger generation. Several treatment options are available today, including pharmacological treatments with atropine eye drops, as well as optical myopia control systems in the form of glasses or contact lenses. These different treatments have been used in clinical practice at Saint-Étienne University Hospital since 2017 for atropine, and more recently with the development of optical myopia control systems and their combinations. Little clinical data has been published to date on these different treatment combinations in the French population. The investigators would therefore like to set up a database to publish their results and share their experience.
