Accuracy of Intraocular Lens Power Formulas Involving 148 Eyes with Long Axial Lengths: A Retrospective Chart-Review Study

Figure 3

Correlations between axial length and absolute error. The associations between axial length and absolute error were analyzed using absolute errors derived from (a) the SRK/T formula (; ; regression equation: ) and (b) the Hoffer Q formula (; ; regression equation: ). Similar analyses were carried out with Group D data only using (c) the SRK/T formula (; ; regression equation: ) and (d) the Hoffer Q formula (; ; regression equation: ).
