Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - alphafilcon A toric
Treatment: Devices - lotrafilcon B toric
Treatment: Devices - senofilcon A toric

Other: Session A - Subjects were first randomized to a session and then randomized to receive one of four lens sequences for that session. Each subject participated in all four sessions. Session A only contains senofilcon A toric and alphafilcon A toric lenses.

Other: Session B - Subjects were first randomized to a session and then randomized to receive one of four lens sequences for that session. Each subject participated in all four sessions. Session B only contains senofilcon A toric and alphafilcon A toric lenses.

Other: Session C - Subjects were first randomized to a session and then randomized to receive one of four lens sequences for that session. Each subject participated in all four sessions. Session C only contains senofilcon A toric and lotrafilcon B toric lenses.

Other: Session D - Subjects were first randomized to a session and then randomized to receive one of four lens sequences for that session. Each subject participated in all four sessions. Session D only contains senofilcon A toric and lotrafilcon B toric lenses.


Treatment: Devices: alphafilcon A toric
Subjects that were randomized to receive alphafilcon A toric during one of the four sessions (Sessions A, B, C and D).

Treatment: Devices: lotrafilcon B toric
Subjects that were randomized to receive lotrafilcon B toric during one of the four sessions (Sessions A, B, C and D).

Treatment: Devices: senofilcon A toric
