ABSTRACT
The study of tiny structures with sizes ranging from 0.1 to 100 nanometers is known as nanotechnology. Nanomedicine is a rapidly growing discipline that employs nanotechnology in medical applications, including targeted therapeutic operations at the molecular level to treat disease or repair cells. The employment of nanomedicine in the management of ocular illnesses has progressed significantly in recent years. The application of nanomedicine based on nanotechnology to cure ocular diseases has become the hope of millions of patients. Nanomaterial-based drug delivery systems are taken into account by an increasing number of scientists. The employment of nano-based medicines presents a novel opportunity to develop drug systems that can go through the protective barriers and sustain sufficient saturation of tissues. This chapter will consider and highlight the current application of diverse bio nanomaterials like electrospun nanofibers, nanoparticles, nanocrystals, liposomes, niosomes, dendrimers, polymeric micelles, hydrogels, and cyclodextrins as ophthalmic methods for drug delivery for the enhancement of ocular bioavailability.
