Study Summary
The purpose of this study was to measure lipid deposits on commercially marketed contact lenses when worn on an extended wear (overnight) basis for 7 days.
Primary Outcome
Film and discrete deposits were assessed with a slit-lamp after 2-5 hours of open eye lens wear. Film deposits were recorded on a 5-point scale, where 0=no deposition, clean surface; 1=slight, deposition occupying 1-5% of lens front surface; 2=mild, deposition occupying 6-15% of lens front surface; 3=moderate, deposition occupying 16-25% of lens front surface; 4=severe, deposition occupying \>25% of lens front surface. Discrete deposits were recorded on a 5-point scale, where 0=no deposition, cl
