Abstract
Nanomaterials have been used in many aspects of ophthalmic treatment. By emphasizing the ubiquitous characteristics of nanoparticles and composites, we first explained their relatively mature applications in drug delivery. Then we reviewed the research on nanomaterials in regenerative medicine and gene therapy in recent years. We also discussed the main limitations of the wider application of nanomaterials in ophthalmology: stability, biotoxicity and preclinical-clinical differences. The development of efficient and non-toxic nanomaterials, combined with appropriate transportation systems and application occasions, will provide more possibilities for the future application of nanomaterials in ophthalmic treatments.
