Comparison between SRK /T, Hoffer-Q, Holladay 1 formulas in mean prediction error and mean absolute error

SRK /T Hoffer-Q Holladay 1 p-value*
PE (D)
Postoperative 1 month -0.14 ± 1.23 -0.04 ± 1.30 0.27 ± 1.32 0.437
Postoperative 3 months -0.19 ± 1.02 -0.09 ± 1.10 0.21 ± 1.19 0.328
AE (D)
Postoperative 1 month 0.91 ± 0.83 0.95 ± 0.88 1.01 ± 0.87 0.893
Postoperative 3 months 0.82 ± 0.62 0.84 ± 0.70 0.90 ± 0.79 0.904

Values are presented as mean ± standard deviation.

PE = prediction error; D = diopters; AE = absolute error.

*One-way analysis of variance.
