Abstract: Artificial intelligence (AI) has been considerable development in AI-assisted cataract research in recent years. It can not only locate and analyzes the structure of the lens,  but also has ability in the classification of cataract diagnosis compared favorably with professional doctors. In the treatment of cataracts,  it provides an objective criterion for the selection of treatment options and the training of cataract doctors to increase the safety of surgery. At the same time,  the population screening can also be achieved by using AI,  laying the foundation for future telemedicine. (Int Rev Ophthalmol,  2020,  44:  386-390)
