Fig. 2From: How does atmospheric pressure cold helium plasma affect the biomechanical behaviour on alkali-lesioned corneas?Normalized stress-relaxation curves resulted for plasma-treated corneas in case of (a) induction of lesion, (b) culture preservation and different exposition times for (c) healthy corneas and (d) lesioned corneas. Median curves are reported together with 50% probability scatter bandsBack to article page
