To compare the ocular tolerance, the safety and the ocular pharmacokinetics of 3 concentrations (0.5% - 1.0% - 1.5%) and the vehicle of T1225 after one drop instillation

The aim of the present study was to compare the ocular tolerance, safety and the ocular pharmacokinetics after a single administration of T1225 eye drops (0.5%, 1.0%, or 1.5%) in healthy volunteers.

Exclusion Criteria:

• Ocular trauma, infection or inflammation within the last 3 months;
• Blepharitis;
• Conjunctival hyperaemia (score >= 2 +);
• Watering (score >= 2);
