Image showing irradiation-free and irradiation-overlapping areas. These images form the basis for calculating δ o and δ z error values. The sum of pixel values seen in the images is calculated with respect to the total sum of pixels in the whole analyzed ROI. Imaging irradiation-free and irradiation-overlapping areas allows to recognize early the critical areas and treat them promptly to avoid permanent sequelae. Although there are individual differences with respect to propensity to side effects, most adverse reactions seen after laser resurfacing appear to be a result of improper treatment technique.
