Fig. 2From: Clinical observations of EVO-ICL implantation and changes in corneal astigmatism using a modified techniqueThe SIA of the total cornea of the modified technique group (centroid: 0.48 × 17° ± 0.48 D) and the standard technique group (centroid: 0.56 × 19° ± 0.44 D) one month after surgery is shown in a double-angle plot. No significant difference was found in SIA between the two groups in centroid analysis (P > 0.05)Back to article page
