Relationship between preoperative corneal astigmatism and postoperative SE prediction error. Scatter plot representation of the SE prediction error against the value and type of the corresponding preoperative astigmatism (Top right). Boxplot representation of the mean values for each type of the preoperative corneal astigmatism (Top left). Boxplot representation of the mean values of the SE equivalent prediction error for each type of preoperative corneal astigmatism (Bottom right). (average axial length eyes, i.e., eyes with an axial length greater than 22.0 mm and less than 25.0 mm)
