Clinical Comparison of Toric Contact Lenses Fit Characteristics

Clinical Comparison of Toric Contact Lenses Fit Characteristics

The purpose of this study is to compare the fit characteristics between four Alcon commercially available toric contact lenses.

Subjects will be expected to attend 3 visits including the screening visit. The total duration of a subject's participation in the study will be approximately 19 days.

Key Inclusion Criteria:

• Successful wear of toric soft contact lenses in both eyes for a minimum of 5 days per week and 10 hours per day during the past 3 months.
• Able to be fit with contact lenses within the available range of sphere, cylinder power, and axes (based on lens availability).
• Best Corrected Visual Acuity (BCVA) better than or equal to 0.10 (logMAR) in each eye.
• Willing to stop wearing habitual contact lenses during in-office visits.
• Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

• Current spherical, monovision or multifocal lens wearer.
• Protocol-specified biomicroscopy findings at screening.
• Current or history of herpetic keratitis in either eye.
• Participation in a clinical trial within the previous 30 days or currently enrolled in any clinical trial.
• Other protocol-defined exclusion criteria may apply.
