PRIMARY outcome

Timeframe: Day 13

Population: One subject was not included in the analysis for all study arms because of protocol deviation. One more subject was excluded form the analysis from Len B control Arm only.

Subjective at-home ratings for ease of Lens handling for insertion will be assessed using a 0-10 scale, (0=very difficult, 10=very easy)
