Eligibility

Key Inclusion Criteria:

• Successful wearers of any commercial soft toric contact lenses (except AOfAHP and daily disposable lenses) in both eyes with at least 3 months wearing experience, with a minimum wearing time of 5 days per week and 10 hours per day.

• Able to be fit with and wear contact lenses within the available range of sphere & cylinder power and axes.

• Best corrected distance visual acuity greater than or equal to 20/25 Snellen (0.10 logMAR) in each eye as determined by manifest refraction at screening.

• Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

• Wearing habitual contact lenses in an extended wear modality (routinely sleeping in lenses for at least 1 night per week) over the last 3 months prior to enrollment.

• Habitual AOfAHP contact lens wearers and habitual daily disposable lens wearers (worn within last 3 months).

• Other exclusion criteria may apply.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of lenses with axis orientation within ± 30 degrees from the intended axis at 10 minutes after lens insertion	The investigator will view the contact lens through a slit lamp (biomicroscope) and record the axis orientation (-179° to +180°) as the number of degrees away from the ideal location (90° axis) either positive or negative depending on the direction (nasal [+] or temporal [-]).	Day 1 Dispense, 10 minutes after lens insertion, for each wear period. Each wear period is approximately 14 days.
