Primary Outcome Measures:
  • Final Comfort [ Time Frame: Day 2, Hour 10 ]
    Comfort was assessed by the participant on a Visual Analog Scale of 0 to 100, where 0=Extremely Uncomfortable ("My eyes are in pain. I cannot tolerate my lenses") and 100=Extremely Comfortable ("My eyes feel GREAT, better than normal. I cannot feel my lenses").


Enrollment: 20
Study Start Date: August 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Lotrafilcon A test/lotrafilcon A control
Lotrafilcon A test contact lens worn first, with lotrafilcon A control contact lens worn second. Each product worn bilaterally for two days as follows: 20 minutes on Day 1 and 10 hours on Day 2.
Device: Lotrafilcon A test contact lens
Silicone hydrogel single vision, soft contact lens with alternate parameters
Device: Lotrafilcon A control contact lens
Silicone hydrogel single vision, soft contact lens
Other Name: Night&Day
Device: Ultra-High Resolution Optical Coherence Tomographer (OCT)
Investigational, nonsignificant risk device for measuring post lens clearance and ocular tissue compression during contact lens wear
Lotrafilcon A control/lotrafilcon A test
Lotrafilcon A control contact lens worn first, with lotrafilcon A test contact lens worn second. Each product worn bilaterally for two days as follows: 20 minutes on Day 1 and 10 hours on Day 2.
Device: Lotrafilcon A test contact lens
Silicone hydrogel single vision, soft contact lens with alternate parameters
Device: Lotrafilcon A control contact lens
Silicone hydrogel single vision, soft contact lens
Other Name: Night&Day
Device: Ultra-High Resolution Optical Coherence Tomographer (OCT)
Investigational, nonsignificant risk device for measuring post lens clearance and ocular tissue compression during contact lens wear

Detailed Description:
The relationship between ocular comfort and the Optical Coherence Tomography (OCT) measurements of post lens clearance and ocular tissue compression was studied.
