Calculation of the Real Corneal Refractive Power after Photorefractive Keratectomy Using Pentacam, When Only the Preoperative Refractive Error is Known

<div>(a) Scatterplot showing correlation between 6 months postoperative Pentacam equivalent K readings (EKR) and real Km (Kr) in diopters (D). Solid = correlation line and dashed = bisector. (b) Bland and Altman plot showing correlation between 6 months postoperative Pentacam equivalent K readings (EKR) and real Km (Kr) in diopters (D), with 95% LoA (range: −1.96 sd to +1.96 sd).</div>
