Remarks on result:

no indication of irritation

Other effects / acceptance of results:

OTHER EFFECTS:
- Visible damage on test system: No observations (e.g. tissue peeling, residual test chemical, non-uniform opacity patterns) were seen in a visually inspection of the corneas after treatment.

ACCEPTANCE OF RESULTS:
- Acceptance criteria met for negative control:
After treatment with the negative control (0.9% sodium chloride solution) the calculated IVIS was 2.8 and, thus, within two standard deviations of the current historical mean of the negative control (IVIS: -1.2 – 3.3).

- Acceptance criteria met for positive control:
After treatment with the positive control (20% Imidazole) the calculated IVIS was 107.7 and, thus, also within two standard deviations of the current historical mean of the positive control (IVIS 74.8 – 137.7).

Therefore, the study fulfilled the acceptance criteria.
