[Expert consensus on the diagnosis and treatment of dry eye during perioperative period of corneal refractive surgery in China (2021)].

The number of corneal refractive surgery in China is increasing year by year, and the quality of surgery is also improved with the trend of diversification and standardization. Dry eye is still one of the common problems associated with corneal refractive surgery. The standardized diagnosis and treatment of dry eye during the perioperative period of corneal refractive surgery is of great significance to improve the postoperative visual quality and satisfaction of patients, and it is also an important part of medical quality control and standardized management in ophthalmology. Therefore, Chinese Optometric Association of Chinese Ophthalmological Society, and the Refractive Surgery Group and the Optometry Group of Chinese Ophthalmologist Association have worked together to address the pathogenesis of dry eye, its evaluation and management before corneal refractive surgery and postoperative nursing care and treatment. The domestic and foreign research findings and the actual clinical situation in China have been considered fully to form this experts' consensus, which could be used as a reference for medical personnel in clinical practice.
