结局指标
主要结局
Mean Ex-vivo Cholesterol Deposits After 30 Days of Wear
时间窗: Day 30, each product
The contact lens (right eye) was removed and stored dry and frozen until analysis. Total cholesterol deposits (cholesterol and cholesterol esters) were extracted from the lens and measured in micrograms. Lower deposits indicate increased lens performance. Study originally intended to analyze 36 lenses per arm, but actual number of lenses analyzed was less due to measurement error.
