What this trial studies

Adults with moderate dry eye who currently use artificial tears will be randomized in a crossover design to receive each of two investigational artificial tear formulations, with participants using one drop per eye of the assigned product during each treatment period. Each person’s total participation is approximately 21 days. Safety and tolerability will be tracked through eye examinations and participant-reported symptoms. Key exclusions include active ocular infection, recent ocular injury, and recent contact lens wear.

Who should consider this trial

Good fit: Ideal candidates are adults with moderate dry eye who currently use artificial tears, can attend all study visits, and meet the other protocol criteria.

Not a fit: People with active eye disease or infection, recent eye injury, or recent contact lens use are excluded and likely would not benefit from participation.

Why it matters

Potential benefit: If successful, the formulations could offer safer or more comfortable artificial tears for people with moderate dry eye.

How similar studies have performed: Other artificial tear formulations have commonly provided symptom relief and shown good tolerability, though each new formulation requires its own safety testing.
