Clinical Trial Summary

The purpose of this study is to assess the clinical performance of two reusable silicone hydrogel contact lenses when worn on a daily wear basis.

Description:

In this crossover study, subjects will wear each lens product for approximately 14 days and attend 7 scheduled visits. The expected overall duration of exposure to the study products is approximately 28 days.

Eligibility

Inclusion Criteria:

• Successful wear of spherical soft contact lenses in both eyes for a minimum of 5 days per week and 8 hours per day during the past 3 months.

• Best Corrected Visual Acuity (BCVA) of 20/25 Snellen (0.10 logMAR) or better in each eye.

• Willing to stop wearing habitual contact lenses for the duration of study participation.

• Other protocol-specific inclusion criteria may apply.

Exclusion Criteria:

• Any eye infection, inflammation, abnormality or disease (including systemic) that contraindicates contact lens wear, as determined by the investigator.

• Any use of systemic or ocular medications for which contact lens wear could be contraindicated, as determined by the investigator.

• Habitual wear of AOHP contact lenses.

• Habitual wear of any daily disposable contact lenses.

• Other protocol-specified exclusion criteria may apply.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Least Squares Mean Distance VA With Study Lenses at Week 1	Visual acuity (VA) was assessed for each eye individually with study lenses in place using logarithmic of the Minimum Angle of Resolution (logMAR) reading charts. LogMAR values typically range from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal distance visual acuity), with a negative value denoting better than 20/20 visual acuity.
