Figure 3 (A) Actual pseudophakic refractions plotted against estimated pseudophakic refractions; the two values were not similar by the Tukey test. (B) The absolute values of the differences between the actual pseudophakic refraction and the estimated pseudophakic refraction. As a group there tended to be less difference from the actual pseudophakic refraction than was the case for calculated values (fig 2). “More” refers to the value 9.13 D.
