Details and patient eligibility

About

The primary objective of the study is to demonstrate that the lubricity of DAILIES TOTAL1® (DT1) lenses after 16 hours of wear is equivalent to the lubricity of unworn DT1 lenses.

Full description

In this study, participants wore study lenses for 2 specified time periods (16 hours and 15 minutes, treatment sequence randomized) following which lenses were collected for ex vivo lubricity analysis. The ex vivo lubricity analysis was evaluated under a separate non-clinical protocol.

Enrollment: 15 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Willing and able to sign Informed Consent document.
• Adapted, current soft contact lens wearer.

• Cylinder between 0.00D and -1.00D (inclusive) in both eyes at Visit 1 manifest refraction.
• Vision correctable to 20/25 or better in each eye at distance with study lenses.
• Willing to wear study lenses at least 16 waking hours in one day and attend all study visits.
• Able to be successfully fitted with study lenses.
• Other protocol-specified inclusion criteria may apply.

Exclusion criteria

• Any ocular infection, inflammation, abnormality or active disease that would contraindicate contact lens wear, as determined by the Investigator.
• Use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the Investigator.

• History of herpetic keratitis, ocular surgery, or irregular cornea.
• Pregnant.
