A Boxplots of PRE and POST mean defect (MD) in 101 eyes of 70 patients. Mean is given as dotted line. Black dots mark 5th and 95th percentiles. Asterisks indicate statistically significant reduction as analyzed by Wilcoxon signed rank test (p < 0.01). B Changes of MD in all 101 eyes as calculated by subtraction of PRE value from POST value (ΔMD). In 64 eyes of 49 patients (63.4%) ΔMD was 0 or negative
