Summary

This study tested a gentle light treatment (low-level light therapy) given before and after Femto-LASIK eye surgery. 61 adults without prior dry eye received either real light therapy or a sham treatment. Those who got the real treatment had more stable tears and fewer dry eye symptoms over 3 months, with no side effects. The approach appears safe and may help people recover more comfortably after LASIK.
