The Web-based Barret True K formula with no history formula has been proven to be a good choice for cataract patients after RK in several studies. The American society of cataract and refractive surgeons provides several IOL formulas for cataract patients who have undergone previous corneal refractive surgery. In cases where only IOL-Master data are available, Holladay 1 (Double-K) \[Holladay 1 (D-K)\] can be used for IOL power calculation in cataract patients with a history of RK. The traditional Haigis formula has also been shown to be effective for cataract patients after RK. To compare the accuracy of four intraocular lens (IOL) power calculation formulas in cataract patients after RK. They are Barrett True-K formula, Holladay 1(D-K) formula, Haigis formula, and MM formula.
