Study summary

The purpose of this study is to assess the safety and efficacy of iontophoretic delivery of dexamethasone phosphate ophthalmic solution using the EyeGate® II Drug Delivery System in patients with dry eye.

Read the detailed description

The objective of this study is to assess the safety and efficacy of Ocular Iontophoresis with Dexamethasone Phosphate 40 mg/mL 7.5 mA-min at 2.5 mA and Ocular Iontophoresis with Dexamethasone Phosphate 40 mg/mL 10.5 mA-min at 3.5 mA compared to placebo for the treatment of the signs and symptoms of dry eye.
