Primary Outcome Measures:
  • Mean Lens Cleanliness as Measured by Light Reflectance [ Time Frame: Day 30 ]
    Lens cleanliness was assessed by total light reflectance, which is a computerized quantitative assessment conducted in a laboratory. The amount of light that scattered off the lens surface in a light field and was assessed using a light reflectance score that ranged from 0 (maximum lens cleanliness; clean/clear) to100 (minimum lens cleanliness; dirty/opaque).

Secondary Outcome Measures:
  • Number of Subjects With no Corneal Staining [ Time Frame: Day 180 ]
    Corneal staining was performed via slit lamp observation of the corneal through a cobalt blue filter and a yellow #12 or #15 filter Wratten filter following contact lens removal and installation of standard sodium fluorescein.

Arms Assigned Interventions
Experimental: Investigational MPS
Investigational multipurpose disinfecting solution (study MPS)
Device: Investigational MPS
Multi-purpose solution
Other Name: Cobra
Active Comparator: Predicate MPS
Opti-Free RepleniSH multipurpose disinfecting solution (predicate MPS)
Device: Opti-Free
Multi-purpose solution
Other Name: RepleniSH

Detailed Description:
A new multi-purpose solution has been developed for optimal lens disinfection and lens wearing comfort, compatible with a wide variety of commercially available lenses. Ten investigative sites were selected to evaluate 274 soft contact lens wearers in a parallel group study of one investigational multi-purpose solution and one marketed predicate solution.
