    Artificial intelligence to estimate the tear film breakup time and diagnose dry eye disease

    The use of artificial intelligence (AI) in the diagnosis of dry eye disease (DED) remains limited due to the lack of standardized image formats and analysis models. To overcome these issues, we used the Smart ...
