[The ophthalmic applications of nanotechnology]

This paper briefly reviews the researches and applications of nanotechnology in ophthalmological field recent years. Nanotechnology is the production of modern science and advanced engineering. In ophthalmological field it is generally applied on foundational investigation, medicine carrying agent, biomaterial, diagnosis and therapy. It helps us observe and control physiological and pathological phenomenon at nanometer level precisely. As new drug carriers, drug-loaded nanoparticles have lots of advantages with its targeting options and sustained drug release. As biomaterial it also has better biocompatible. It is a promising material in clinical application. The diagnosis and treatment level would be improved definitely by nanotechnology.
