ABSTRACT=In recent years, micro-nano robots have found extensive applications in the field of medicine. Among these, micro-nano robots demonstrate significant potential for the treatment of eye diseases. Micro-nano robots can penetrate eye tissue barriers to directly target the posterior segment of the eye for precise drug delivery, enabling non-invasive or minimally invasive treatment. This review explores the primary fabrication methods and propulsion mechanisms of various micro-nano robots, and their applications in treating various eye conditions, offering inspiration and guidance for advancing the use of micro-nanorobots in ophthalmic therapies.
