Quantitative analyses showed that there was no significant difference in glucose levels between the ‘before/during the surgery’, detected by UV-hexokinase (n = 10) and hydrogen peroxide (H2O2)-electrode (n = 8; unfortunately, 2 samples were lost during the surgery) methods. In addition, the levels from the anterior chamber and blood were not significantly different, p > 0.05. Graphs are presented as median with interquartile range, the 25th and 75th percentile. The data were analyzed using Student’s t-test and one-way ANOVA followed by a Bonferroni post hoc test. UV: UV-hexokinase method; H2O2: H2O2-electrode method.
