About This Trial
By using 16S rRNA sequencing technology to analyze the changes in ocular surface microbiota before and after surgery, as well as the impact of changes in ocular surface microbiota on FS-LASIK induced DES, new treatment ideas are provided for corneal FS-LASIK induced DES patients, and the incidence of FS-LASIK related DES is reduced.
