Participant Flow

289 Subjects were enrolled in the study. 7 subjects did not meet the eligibility criteria. 282 subjects entered Phase I. During Phase I, 55 subjects were either lost to follow-up or discontinued. The remaining 227 subjects were randomized to either comfilcon A or balafilcon A and entered Phase II. 146 subjects completed Phase II

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

PRIMARY outcome

Timeframe: 1-Month Follow-up

Population: The analysis population consists of subjects that completed all study visits in Phase I without a major protocol deviation and were correctly classified as either repeat Mucin Ball former or Non-repeat Mucin Ball former. Five subjects had incorrect Mucin Ball classification and 8 subjects met study objective.

The percentage of Subjects that experienced Corneal Inflammatory Events within their Mucin Ball classification.
