Group Intervention Description AO toric, then AOHG toric Lotrafilcon B toric contact lenses Lotrafilcon B toric contact lenses, followed by lotrafilcon B toric contact lenses with HYDRAGLYDE, as randomized. Each product worn in both eyes for approximately 30 minutes, with a 30-45 minute washout between the removal of Pair 1 and insertion of Pair 2. AOHG toric, then AO toric Lotrafilcon B toric contact lenses with HYDRAGLYDE Lotrafilcon B toric contact lenses with HYDRAGLYDE, followed by lotrafilcon B toric contact lenses, as randomized. Each product worn in both eyes for approximately 30 minutes, with a 30-45 minute washout between the removal of Pair 1 and insertion of Pair 2. AO toric, then AOHG toric Lotrafilcon B toric contact lenses with HYDRAGLYDE Lotrafilcon B toric contact lenses, followed by lotrafilcon B toric contact lenses with HYDRAGLYDE, as randomized. Each product worn in both eyes for approximately 30 minutes, with a 30-45 minute washout between the removal of Pair 1 and insertion of Pair 2. AOHG toric, then AO toric Lotrafilcon B toric contact lenses Lotrafilcon B toric contact lenses with HYDRAGLYDE, followed by lotrafilcon B toric contact lenses, as randomized. Each product worn in both eyes for approximately 30 minutes, with a 30-45 minute washout between the removal of Pair 1 and insertion of Pair 2.
- Primary Outcome Measures
Name Time Method 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.
