Design outcomes

Primary

MeasureTime frame
Subject incidence of lens opacification event development or progression by month 12, based on a change of â?¥ 1.0 in P, â?¥ 1.0 in C, or â?¥ 0.7 in NO in the LOCS III score.Timepoint: Subject incidence of lens opacification event development or progression by month 12 exceeding a predefined level at any of 3 key lens locations using LOCS III score.

Secondary

MeasureTime frame
Adverse event incidence and changes in safety analytes.Timepoint: [ Time Frame: One year ] [ Designated as safety issue: Yes ] ;Subject incidence of lens opacification event development or progression by month 6, based on a change of â?¥ 1.0 in P, â?¥ 1.0 in C, or â?¥ 0.7 in NO in the LOCS III scoreTimepoint: [ Time Frame: One year ] [ Designated as safety issue: Yes ]
