PRIMARY outcome

Timeframe: 12 Months

Population: All subjects who completed the 12-month visit or underwent a glaucoma-related secondary surgical procedure prior to the 12-month visit were evaluated in this analysis.

Proportion of subjects achieving a 20% or greater reduction in IOP from baseline on the same or less number of medications. Subjects who underwent a glaucoma-related secondary surgical intervention prior to the 12-month visit were considered failures in this analysis.

PRIMARY outcome

Timeframe: 12 Months

Population: All subjects who completed the 12-month visit or underwent a glaucoma-related secondary surgical procedure prior to the 12-month visit were evaluated in this analysis.

Mean change in IOP from baseline was calculated for subjects who completed the 12-month visit and the worst within-eye IOP was used for subjects who underwent a glaucoma-related secondary surgical intervention.
