- Corneal Staining [ Time Frame: 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.
- Subjective Lens Wearing Comfort [ Time Frame: 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 [ Time Frame: 4 weeks ]This will be assessed by the tear break-up time on the lens surface, measured in seconds.
