主要结局

Front Surface Lens Deposits

时间窗: 7 days

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, clean surface; 1=microdeposits (less than or equal to 10 dots); 2=microdeposits (greater than 10 dots); 3=macro deposits; 4=one or more jelly bumps. Participants were classified into Front Surface Lens Deposits \<2 (less than grade 2 for both film and discrete) and into front surface lens deposits \>1 (greater than grade 1 for either film, discrete, or both).
