Percentage of Lenses With Axis Orientation Within Plus or Minus 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 \[-\]). No hypothesis testing was prespecified for this endpoint.
Time frame: Day 1 Dispense, 10 minutes after lens insertion, for each wear period. Each wear period is approximately 14 days according to randomization assignment.
