Contact Lens Related Dry Eye Syndrome
Conditions
Brief summary
The objectives of the investigation will be to assess the effect of the repeated usage of a new eye drop on the tear film characteristics of silicone hydrogel contact lens wearers with contact lens related comfort problems and to quantify any potential benefit.
Interventions
1 drop in each eye four times a day for a period of 30 (± 3) days
One month of contact lens wear with no eye drop use
1 drop in each eye four times a day for a period of 30 (± 3) days
