Effect of WRAD Lens on Axial Growth and Refraction in Low-hyperopic Chinese Children
Sponsor: He Eye Hospital
Summary
Myopia is one of the most common visual impairments worldwide.This not only poses long-term risks to individual health but also imposes significant medical and economic burdens on society. \[6\] Therefore, delaying the onset of myopia and effectively controlling its progression has become an urgent issue that needs to be addressed.In recent years, a new type of highly aspherical lenslet (HAL) has been proposed. Its optical design includes a refractive correction area in the central region and a peripheral annular area. This annular area can form a "myopic defocus zone", increasing the myopic defocus signal around the retina. Studies have confirmed that this design can effectively slow down the progression of myopia in already myopic children. However, it is currently unclear whether this lens has a preventive effect on children who are not yet myopic but have a risk of developing myopia.
