A Succinct Study in the Developments of Nano Ocular Delivery Techniques

The study of materials physical, chemical, and biological characteristics at the nanoscale is referred to as nanoscience. Materials with at least one dimension in the nanoscale are used and constructed in nanotechnology [1]. Outstanding mechanical, electrical, optical magnetic and chemical properties are displayed by some nanoscale materials. Drugs and drug delivery systems can benefit from these qualities by having better physiochemical and biological properties [2-4]. Additionally, the use of nanotechnology in ocular disease diagnosis and treatment has advanced quickly. Polymer based systems, nanoparticles, and nanovescicles seem promise for controlled and extended drug release, which could result in improved therapeutic efficacy. Moreover, despite ongoing issues with the device’s scalability and biocompatibility, micro and nanotechnology has the potential to revolutionize the treatment of ocular diseases. To validate these innovations in the therapeutic context of ophthalmology, more clinical research is required. However, over the past ten years, fundus lesions and ocular cancers have been included in the rapidly expanding field of nanomedicine in ophthalmology. By increasing the drugs solubility, stability and permeability and prolonging its residence duration, loading it into an ocular nano-level DDS (targeted drug delivery system) improves the drug’s effectiveness. Notably, a thorough introduction is given to the latest developments in nano carrier DDS and their applications in the management of different ocular conditions. Lastly, more discussions are given to the present difficulties as well as potential future paths and viewpoints about the use of nanocarrier based DDS for ocular treatments.
