Studies have shown that atropine eye drops are effective in controlling myopia in children and adolescents. Among them, low-concentration atropine has few side effects and is the primary recommendation, but many clinical practices and studies suggest that its effect in controlling myopia is limited. 1% atropine ophthalmic drug has obvious curative effect advantages in controlling myopia, but its side effects such as photophobia and blurred vision limit its popularization and use. In the early stage, our research group used 1% atropine 5+3 myopia control (eye instillation for 5 consecutive nights in the first week of each month, one night per week in the 2nd, 3rd, and 4th weeks; after 3 months of monocular application, change to the contralateral eye), data from retrospective clinical studies have shown that it can significantly reduce side effects and improve compliance, but there is currently a lack of evidence from prospective clinical studies. Therefore, this study intends to use a randomized controlled trial, with 1% atropine used in both eyes once a week as the control group, to evaluate the effect of the 5+3 regimen in controlling myopia (spherical equivalent and axial length), safety (accommodation amplitude, amount of phoria, binocular vision function, etc.), and the compliance and side effects (photophobia, blurred vision, etc.).

In the early stage, our research group used 1% atropine 5+3 myopia control program and 1% atropine alternate eye myopia control program.
