Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment

Further study details as provided by Abbott Medical Optics:

Primary Outcome Measures:
  • Number of Eyes With No Change in Corneal Staining [ Time Frame: Change from baseline after 1, 2, 4 and 6+ hours of wear ]
    Subjects examined after corneal staining (a method used to assess the condition of the cornea) using a slit lamp to determine change from baseline and rated based on the following scale: 0=no change from baseline, 1=trace, 2=mild, 3=moderate, 4=severe.

Enrollment: 30
Study Start Date: April 2009
Study Completion Date: June 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
