Lipid-containing, preservative-free artificial tears used regularly.
Reason: lipid-containing drops replenish the deficient tear-lipid layer in MGD and preservative-free formulations avoid ocular-surface toxicity. The other options (vasoconstrictor drops with preservatives, daytime high‑viscosity ointments, and astringent tears) can irritate, promote gland obstruction/stagnation, or damage the surface and thus worsen MGD-related dry eye.
