With the societal aging and the excessive use of video terminals, the prevalence rate of dry eye is increasing, and the causative factors are complex and diverse. Unremitting research and discussions on the diagnosis and treatment of dry eye have been carried out. An expert consensus on this issue was released in 2013. To further standardize and promote the diagnosis and treatment of dry eye, the Cornea Group of Chinese Ophthalmological Society and the Cornea Group of Ophthalmology Branch of Chinese Ophthalmologist Association have recently summarized the latest clinical findings and experience. A new version of the expert consensus has been formed to meet the needs of clinical practice.
