Abstract
Myopia presents a formidable challenge, especially in children, where clinical management involves the use of atropine and 7-methylxanthine, necessitating multiple doses, strong side effects and encountering suboptimal compliance due to children's resistance. In response to these issues, our research proposes a self-generated electricity-driven drug delivery system (EDDDS) designed for precision myopia treatment. The EDDDS intelligently releases therapeutic drugs, such as atropine, at ocular tissues using drug-coated nanogenerators, aiming to effectively slow down the progression of myopia. This system combines nanotechnology and smart drug delivery mechanisms to achieve controlled and responsive drug administration. The nanogenerators embedded in the EDDDS generate electric fields that trigger drug release upon closing eyes conditions, providing targeted treatment. Simultaneously, the weak voltage can effectively relieve the ciliary muscle, offering additional benefits for myopia management. In vitro and in vivo experiments have demonstrated the efficacy and potential of the EDDDS in precisely modulating myopia progression. The proposed EDDDS holds significant promise as an advanced and high-precision therapeutic approach for myopia management. Its potential to address the limitations of current treatments makes it a promising avenue for future research and clinical applications.
