Clinical Question:
Does oral omega-3 supplementation improve symptoms of dry eye disease?
Bottom Line:
The evidence for omega-3 is inconsistent. The best quality randomized control trial (RCT) found that omega-3 supplementation does not improve dry eye symptoms or function. Smaller RCTs suggest statistically significant benefits in symptom scores that are not always clinically relevant. At best^ omega-3 will improve symptoms about 3.9 points more than placebo on an 18- point symptom score.
