[Research advances in contact lens-associated dry eye].

Dry eye is the most common disease in ophthalmic clinics besides refractive error, which seriously affects the life quality of patients and has become an important public health problem in China. Dry eye as a kind of multifactorial disease can be induced or accelerated by contact lens wear, which is considered as one of the risk factors of dry eye. Studies have shown that the incidence of dry eye is higher in contact lens wearers than in normal people. In 2017, the Tear Film and Ocular Surface Society included contact lens-associated dry eye (CLADE) in the iatrogenic dry eye for the first time, and its importance is evident. However, ophthalmologists mostly used to focus on serious complications such as keratitis caused by contact lens wear, and CLADE has not been well valued and understood. This article reviews the latest studies on the epidemiology, pathogenesis, diagnosis, prevention, and treatment of CLADE.
