Primary Outcome Measures
NameTimeMethod
Percentage of Lenses With Axis Orientation Within ±30 Degrees From the 90 Degree Axis (Ideal Location)Day 1, 10 minutes after lens insertion, each product

Each lens was classified based on whether the absolute difference between the axis location and 90° was less than or equal to 30° (ie, lens axis located between the 60° and 120° axis inclusive). Inferential testing was not planned for this primary effectiveness endpoint.
