Detailed case-based data on TBUT, Schirmer I test, and OSDI scores before and after corneal CXL. Each symbol and its related line represents a case. a shows the TBUT changes after corneal CXL, and the red dashed line shows the threshold for abnormal TBUT (10 s). b shows the Schirmer I test changes after corneal CXL, and the red dashed line shows the threshold for abnormal Schirmer I test (15 mm). c shows the OSDI score changes after corneal CXL, the green dashed line shows the threshold for abnormal OSDI score (12), and the red dashed line indicates the threshold for severe ocular surface disease (32). As demonstrated, most cases had a baseline abnormal TBUT, Schirmer I test, and OSDI scores with no significant change after corneal CXL
