  • All subjects must meet all the inclusion & exclusion criteria to enter this study in pre-operative phase.
  • Eligible subjects will be enrolled after a scheduled operative procedure.
  • There is SEVEN visits in this study (one screening eligibility phase up to 7 days before OP day, and four post-op treatment scheduled visits consisting on 1st , 3rd day, 5th day, 12th day and two follow up visit on the 28th and the 42nd post-operative day.
  • During each scheduled visit, each subject will have colored picture of his wound after dressing been removed, and on visit V6 for wound evaluation by blinded PI.

Number of subjects: It is expected to recruit ≧150 eligible subjects.

Study Duration: About eighteen month.
