PRIMARY outcome

Timeframe: 6-8 Hours Post lens insertion

Population: All subjects that were dispensed at least one study lens throughout the duration of the study.

Corneal swelling measurements were taken in the right eye during slit lamp evaluations, 6-8 hours post lens insertion. The average corneal swelling per lens was reported.

SECONDARY outcome

Timeframe: 6-8 hours post lens insertion

Population: All subjects that were dispensed at least one study lens throughout the duration of this study.

Limbal redness was assessed in both eyes using a slit lamp, 6-8 hours post lens insertion. Redness was assessed in 4 regions of the eye (nasal, temporal, inferior and superior) and was graded with a 5-point scale (i.e. Grade 0= None, Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe). For each region (nasal, temporal, inferior and superior) the average grade was calculated by lens. The Total Grade was then calculated by summing all the average grade for each region. The regional average grade ranges from 0 to 4. The total Grade ranges from 0 to 16.
