- Brief Summary
The primary objective of this study is to evaluate the axis orientation of LID226397 toric contact lenses.
- Detailed Description
Subjects will be expected to attend 7 visits including a screening visit. The total duration of a subject's participation in the study will be approximately 40 days.

- 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
- 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.

- Primary Outcome Measures
Name Time Method Percentage of Lenses With Axis Orientation Within Plus or Minus 30 Degrees From the Intended Axis at 10 Minutes After Lens Insertion Day 1 Dispense, 10 minutes after lens insertion, for each wear period. Each wear period is approximately 14 days according to randomization assignment. 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 \[-\]). No hypothesis testing was prespecified for this endpoint.
