In this study, dry eye disease (leukoaraiosis) is used as a model disease, and the methodological system for evaluating the clinical efficacy of Chinese medicine for dry eye disease is constructed with the core of "subgrouping dynamic and static parallel group design", so as to carry out a real-world demonstration study of dry eye disease as a dominant disease in Chinese medicine treatment. The purpose of this study is to demonstrate the selection of individualized clinical interventions and the superiority of dynamic diagnosis and treatment using dry eye as a disease model. The study provides a clinical example of a subgroup-based dynamic and static parallel group design for TCM clinical research on "disease-based integrated treatment". Based on the conclusions of the efficacy evaluation study, investigators will provide real-world clinical data of dry eye syndrome for the artificial intelligence prediction of the integrated platform of individualized clinical evaluation and evidence support of Chinese medicine with multi-source data integration.
