Dear Editor, With great excitement, we read the article entitled “Accuracy of the Barrett Universal II formula integrated into a commercially available optical biometer when using a preloaded single‐piece intraocular lens” by Mieno et al.[1] We congratulate the authors on their detailed analysis of the accuracy of Barrett Universal II, a newer generation formula, and comparison with commonly used formulas for VivinexTMiSert® XY1 IOL. This lens has been in use for quite some time now but not much study has been published on it. Since the protocols on clinical studies on Intraocular lens (IOL) power calculation and biometry are continually getting updated, it would be very helpful for the readers if the authors could clarify the following points.
