Abstract: The theory of peripheral retinal defocus is currently the mainstream theory for myopia prevention and control. Based on the retinal peripheral defocus technology, there are orthokeratology, defocus soft lenses, defocus frame glasses, etc., all of which are in the process of lowering retinal defocus to control the growth of myopia, and they have achieved a better effect for myopia prevention and control. Based on the theory of retinal peripheral defocus, our independently developed multispectral refractive topography (MRT) can quantify the retinal hyperopic defocus, and this breakthrough technology once again verifies that retinal peripheral defocus is the focus of myopia prevention and control. In this article, we review the application and progress of retinal peripheral defocus. (Int Rev Ophthalmol, 2024, 48:  51-55)
