Oral long‐chain omega‐3 PUFAs vs placebo or no treatment

Change in ocular surface staining at 1‐month (with actual · people with dry eyea

Oral long‐chain omega‐3 PUFAs (ie, EPA and DHA) showed no clear difference in change in ocular surface staining at 1‐month (with actual compared with placebo or no treatment (low certainty).
