Overview

Tear film stabilization (pre-corneal) refers to the maintenance and regulation of the thin, multi-layered fluid film that coats the anterior surface of the cornea. This tear film is essential for ocular surface health, optical clarity, and comfort. Its stability depends on a complex interplay of lipids, aqueous components, and mucins, and it is not a single molecular target but a physiological process involving multiple components. Instability is a key factor in dry eye disease. Therapeutic interventions aim to restore or maintain tear film stability by supplementing tear components or addressing underlying causes of instability such as inflammation.

Mechanism of action

Artificial tears provide lubrication and supplement tear film components. Cyclosporine and lifitegrast reduce inflammation to improve tear production and quality.
