Lipid layer thickness (in ICU) at consecutive measurements.
perfluorohexyloctane
The LLT at 4 and 12 weeks were compared to the LLTat baseline using the Wilcoxon test. All p-values were adjusted for 2 comparisons according to the Bonferroni method. An asterisk with the corresponding p-value indicates a significant change compared to the baseline. ICU = Interferometric Colour Units; CN = cationic nanoemulsion; F6H8 = perfluorohexyloctane.Higher order aberrations as measured by the RMS values did not differ at baseline (H (3) = 3.0; p = 0.4) between the three groups. Neither the application of CN (X2 (2) = 0.7; p = 0.7) nor of F6H8 (X2 (2) = 1.0; p = 0.6) lead to a change in the RMS values within a 12-week observation period (
