Figure 6From: Vector analysis of low to moderate astigmatism with small incision lenticule extraction (SMILE): results of a 1-year follow-upThe predictability of cylindrical refraction with SMILE surgery. The absolute TIA versus SIA with SMILE surgery at 1 month (A), 6 months (B) and 12 months (C). Above the green dashed line in middle is overcorrection and below is undercorrection. The red solid line indicates the outcome of linear regression analysis.Back to article page
