Modern Approaches in Nanotechnology for Ocular Diseases

Nanotechnology encompasses the study, processing, and application of various functional materials, tools, and systems, as well as the manipulation of substances at the nanoscale. A specific application of nanotechnology is "nanomedicine," which involves its use in the detection, management, prevention, and monitoring of a wide range of diseases. Research in this field can potentially accelerate disease treatment and drug development. In cases involving ocular diseases, medications delivered through eye drops must traverse several ocular barriers to reach the posterior segment of the eye. Nanotechnology offers significant advantages for these treatments. It can effectively address the limitations of conventional ocular delivery methods, which often suffer from poor therapeutic efficacy and possible side effects due to invasive surgery or systemic exposure.
