Studying tear changes in people using Xiidra for dry eye
Part of Eyes & vision clinical trials.
This study tests whether the dry eye medication Xiidra (lifitegrast) changes the makeup of your tears. It looks at biomarkers in tears to understand how the medicine works and if it can help relieve dry eye symptoms.
