IOL calculation formulas | SRK/T | Holladay II | Haigis |
|---|---|---|---|
Predicted refraction (D) | −0.19 | + 0.62 | + 1.30 |
Actual postoperative spherical equivalent (D)a | + 1.25 | + 1.25 | + 1.25 |
Postoperative refractive error (D) (Postoperative Refractive Error = Actual Postoperative Spherical Equivalent – Predicted Refraction) | + 1.44 | + 0.63 | −0.05 |
IOL degree when target diopter equals to 0 (D) | 20.5 | 21.5 | 22.5 |
