Visual Performance of Eyes with Residual Refractive Errors after Implantation of an Extended Vision Intraocular Lens

Figure 2

Mean logMAR distance corrected visual acuity (CDVA) (reference situation) and with a residual mixed astigmatic refraction induced by adding a combination of −0.25 diopter (D) spherical and 0.50 D cylindrical lenses placed in vertical (against the rule-ATR), oblique, and horizontal (with the rule-WTR) positions. Represents statistically significant differences among the four situations analyzed.
