简要总结
The purpose of this study is to evaluate corneal staining observed after 2 hours of wear with an investigational contact lens against both PureVision contact lenses pre-cycled with Biotrue and Biofinity contact lenses pre-cycled with RepleniSH.
详细描述
Subjects will be randomized in a 1:1:1:1 manner to receive one of 4 regimen sequences with lens and multipurpose disinfection solution (MPDS) combinations. The expected duration of subject participation in the study is approximately 1 week with 2 study visit days.

结局指标
主要结局
Average Percent Area of Corneal Staining
时间窗: Hour 2 (each wear period)
A slit lamp examination was performed by the investigator to assess corneal staining. Percent of solution-related corneal staining area was assessed first in each of the 5 corneal regions: central, superior, nasal, inferior, and temporal. The average of corneal staining area was then calculated as the average over all 5 regions. Each eye was treated differently and was graded separately. No hypotheses were formulated; no inferences were made, and only descriptive statistics were used in the reporting.
