Comment on Accuracy of Intraocular Lens Formulas in Eyes With Keratoconus

We read with great interest the excellent article by Wang and associates.1 We recognize that intraocular lens power calculation in patients with keratoconus is challenging. Determining the accurate keratometry readings, axial length, and anterior chamber depth can be difficult in these eyes, which can lead to inaccurate and unpredictable results with a tendency to hyperopic refractive surprises.1 –4 To the best of our knowledge, this is the first study that reports the Barrett Universal II as the most accurate formula in mild keratoconus (stages I and II).
