During Phase I, subjects are classified as either repeated Mucin Ball former or Non-Repeat Mucin Ball former. The 227 subjects that entered Phase II kept there Mucin ball classification, but were still randomized to either comfilcon A or balafilcon A. All comparisons are made between Mucin Ball classification
