Fig. 5From: Real-world refractive outcomes of toric intraocular lens implantation in a United Kingdom National Health Service settingVector analysis showing the magnitude and angle of the error in astigmatic correction of individual eyes (black dots). The combined result is an error vector with magnitude of − 0.42 D and angle of 4.63° (red dot), indicating an overall tendency towards under-correction of astigmatismBack to article page
