Arm && Interventions

Group	Intervention	Description
Clear Care	Clear Care	Peroxide-based lens care regimen.
Investigational MPS	Multi-purpose disinfecting solution	AMO Investigational MPS.
Opti-Free RepleniSH	Opti-Free RepleniSH	Multi-purpose disinfecting solution (Alcon).

Primary Outcome Measures

Name	Time	Method
Corneal Staining	4 weeks	Corneal staining will be assessed with sodium fluorescein dye on the ocular surface. The cornea is split into 5 sections, each section is evaluated by staining type, depth, and extent is graded on a 0 to 100 scale with higher scores indicating more staining. The possible total range for the total score per eye is 0 to 50,000 (100x100x100=10,000 per section) with values higher than 1200 being clinically relevant.

Secondary Outcome Measures

Name	Time	Method
Subjective Lens Wearing Comfort	4 weeks	This will be assessed by a questionnaire on patient-perceived lens comfort and any symptoms of discomfort on a 0 to 100 scale.
Dryness	4 weeks	This will be assessed by the tear break-up time on the lens surface, measured in seconds.
