PRIMARY outcome

Timeframe: up to 1 year

Population: This primary analysis includes the cohort of all 218 randomized participants. The measured values stratify participants by solution group, however, the statistical analysis reports on the entire cohort (both solution groups) consistent with the primary aim of the study.

SECONDARY outcome

Timeframe: up to 1 year

Population: All participants in which valid lens bioburden data was available

Microbial bioburden on lenses was determined with predetermined cutoffs to identify substantial bioburden as high levels of normal flora or presence of pathogenic abnormal flora on lenses
