Lens Wettability
Time Frame: Baseline - after 2 hours of lens wear
|
Lens wettability on a 0 to 4 descriptive scale, 0.5 steps (0 - Very poor: Immediately displaying non-wetting areas on the lens surface, immediate drying time, 1 - Poor: Irregular surface appearance, drying time << blink time, 2 - Acceptable: Smooth surface appearance immediately after the blink becoming irregular after a while, drying time ≤ blink time, 3 - Good: Typical soft lens appearance with long drying time, 4 - Excellent: Appearance similar to a healthy cornea with very long drying time)
