Conventional drug delivery systems often suffer from poor bioavailability, rapid clearance, and inadequate targeting, limiting their clinical efficacy. Recent advances in smart nano-in-micro (NIM) platforms have emerged as a transformative strategy, combining the precision of nanoscale drug carriers with the stability and sustained-release capabilities of microscale matrices. These hierarchical systems enable enhanced drug penetration, prolonged retention, and targeted delivery to both anterior and posterior ocular segments. This review highlights the latest developments in NIM platforms, focusing on material innovations that optimize drug loading, release kinetics, and biocompatibility. The shared physicochemical properties of nano-micro particles that influence their performance across different administration routes (topical, intravitreal, subconjunctival), supported by mechanistic insights into their interactions with ocular tissues are discussed. By bridging nanoscale engineering with clinical ophthalmology, NIM platforms represent a paradigm shift in ocular therapeutics, offering the potential to revolutionize treatment for previously intractable eye diseases.Keywords: nano-in-micro, nanoparticles, ocular diseases, ocular drug delivery |
