Notes: Symptoms = as assessed with symptom questionnaires or visual analogue scales, tear stability = invasive or non-invasive tear breakup time, Meibomian gland function = meibum quality, expressibility, lid margins, or meibography.
Abbreviations: aS, improved symptoms; T, improved tear stability; M, improved meibomian gland function.
